ANNUAL REPORT 2008 - INTRODUCTION
1. INTRODUCTION
1.1 History
Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an
association of six institutions with experience and traditions in research and
development in the field of Telecommunications:
• Instituto Superior Técnico (IST);
• Universidade de Aveiro (UA);
• Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC);
• Portugal Telecom Inovação, (PTIn);
• Nokia Siemens Networks S.A;
• Universidade da Beira Interior (UBI).
it is organised around three sites: one in Aveiro, in the University Campus,
another in Coimbra, in Site II of the University of Coimbra and the third one in
Lisbon, in Instituto Superior Técnico. In addition there is an external laboratory
in Porto, shared by the Faculty of Engineering and the Faculty of Sciences of the
University of Porto, and three delegations one in Leiria, in the ―Escola Superior
de Tecnologia e Gestão‖ of the Leiria Polytechnic (IPL), one in Lisbon, in Instituto
Superior de Ciências do Trabalho e da Empresa (ISCTE) and one in Covilhã, in
the University of Beira Interior.
Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros)
grant from Programme CIÊNCIA, through three contracts signed in 1991. This
investment enabled new infrastructures to be built and research laboratories to
be equipped at each site.
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994.
Since 1993, it activities proceed regularly.
it statutes were first approved in 1992, modified in 1997 and modified again in
2003. New
site statutes deriving
from
it
statutes were approved
and
implemented in 2005.

ANNUAL REPORT 2008- INTRODUCTION
Key developments in 2008 are highlighted ahead. Details are included in the
sections dealing with each of the research areas.
1.2 Management
it is managed by a Board of Directors, elected by the General Assembly, and by
Site Management Boards, which include the site members of the Board of
Directors. Site Management Boards enjoy ample freedom to deal with current
affairs and usually meet weekly. The Board of Directors meets at least once a
month.
it scientific activities are overseen by the Scientific Board, which includes all it
researchers holding a Ph.D. degree. The Scientific Board meets in Plenary or in
Committees, both permanent and temporary. There are two permanent
committees: the Science and Technology Committee and the Research Group
Coordination Committee.
it Work Plan and the Annual Report are discussed with the Advisory Committee,
formed by three independent experts in the field of telecommunications (Dr.
Roland Huber, Prof. Sir John O‘Reilly and Prof. Martin Tomlinson) acting in a
personal capacity, and together with the Accounts (after legal certification) are
subsequently submitted to the General Assembly for approval.
The General Assembly met formally twice. The first meeting was held on March
25, in the Meeting Room of the Coimbra site, to discuss and approve the 2007
Annual Report and Accounts. The second meeting took place on December 22, in
the Meeting Room of the Aveiro site, to approve the Work Plan and Budget for
2009.
The Research Group Coordination Committee also met twice during 2008. On the
first meeting, held on February 25, at Hotel da Lezíria (Vila Franca de Xira), the
Draft Proposal of the 2007 Annual Report, was discussed and received a
favourable opinion. The coming it evaluation was discussed and basic guidelines
to prepare the visit of the Advisory Committee, which took place on March 6—7.
Scientific productivity was debated and measures to improve it were presented
with emphasis on identifying non productive it members. On the second
8
meeting, held on December 15, in the meeting room of Hotel D. Luis (Coimbra)
site the Work Plan and Budget for 2009 was discussed and received a favourable
opinion. Procedures to measure scientific productivity and to identify non
productive it members were finally agreed.
Prof. Afonso Barbosa, resigned from the Board of Directors on March, after 15
continuous years as a Member of the Board. In recognition of his work, which
cannot be praised enough, he was awarded the title of it Honorary Associate by
the General Assembly in its March meeting.
The Board of Directors, from then on, reduced to four members, met once a
month. Since the current Board of Directors mandate ends with the presentation
and approval by the General Assembly of the 2008 Report and Accounts,
Associates are urged to nominate a full (five member) Board of Directors.
1.3 Highlights of 2008
As 2007, for many reasons 2008 was again a very good year for it.
Firstly the scientific output reached a new peak and the number of papers (178)
published in international refereed papers for the first time exceeds the number
of researchers (holding a Ph. D.) on the FCT data base for the 31 st of December
2007 (173). One of it researchers was elevated to the rank of IAPR fellow, and
another received the UTL/Santander Totta prize (the second time in a row where
this prize distinguishes an it reseacher) thus underlining the quality and the
relevance of their work. There was also a very large increase in the number of
MSc students. (from 78 to 159 due to the Bologna process).
Secondly, funding was, again, plentiful and timely. FCT made good on its
promises both at the continuing IT – Laboratório Associado contract and on the
first payments for the new contracts.
FCT granted it an extension of the IT – Laboratório Associado contract, until
June 2008, thus not only guaranteeing funds for the first 6 months of 2008,
9
when the new structural fund programmes were not yet available, but also
prolonging this very important contract and providing a bridge for what we
expect to be the new associate laboratory contract. Payments for 2007 and 2008
were made as if the IT — Laboratório Associado has continued.
The IT — Laboratório Associado contract, with a total funding of 6.66 M€ of
which 6.5 M€ (97.5 %) was spent in spite of all the difficulties experienced
during the contract period (2002—2008). It should be noted that 2008 expenses
have not yet been certified, so that the eligible expenses may differ somewhat
from the 6.5 M€. No doubt, due to this fact and the fact that the 2007
certification of expenses is not yet final, FCT payments for this contract are still
1.6 M€ in arrears.
Funding for 2007, for which it was granted permission by FCT to use it up to
March 31, 2009 was totally spent (or closely). The rules for the 2008 funding are
yet unclear but it appears likely that it will have to be used up to December 31,
2009.
The only reason why it activities were not heavily imparted by FCT debt (of 1.6
M€) is twofold: one, FCT funding for 2007 and 2008 proceeded regularly; two,
time limits for expenditure were postponed.
Contrary to our initial expectations, it was not evaluated by an FCT appointed
panel during 2008, a process which is now foreseen for the Summer of 2009.
Highlights of 2008 were:
University of Beira Interior was admitted as an it associate, during the
General Assembly meeting that took place on December, 22;
The Covilhã external laboratory was upgraded to delegation, during the
General Assembly meeting of May, 14, thus reflecting the growing
number of researchers (holding a Ph.D.) and the diversity of research
areas;
10
The external laboratory of Porto, shared by the Faculty of Sciences and
the Faculty of Engineering of the University of Porto, was created by
decision of the General Assembly, on its meeting of May 14.
The number of scholarships increased again in 2008, reaching an all time level.
This is an important step in improving it performance and impact.
During 2008, 106 nationally funded and 46 internationally funded projects were
active, as shown in section 2.2. As in previous years, involvement of it
researchers namely from the Lisbon site in European Commission funded
projects were carried out through it associates due to current rules of
participation.
During 2008, it received the following visits (invited speakers for short courses

activities:
Table 1 - Foreseen and achieved scientific output in 2008.
Achieved scientific output exceeded our forecast, in the all important items of
books and book chapters and papers in journals and was somewhat shorter on
the target of papers in conference proceedings.
12
The concluded final year projects are the remaining pre-Bologna cases. For
comparison they may be added to achieved MSc theses, thereby exceeding the
forecast. The number of concluded PhD theses continues to fall short of the
expected value, showing that supervisors systematically underestimate time
requirements.

4.1.3 Summary of Research Achivements
Research work in the Wireless Communications Scientific Area of it covers the
main aspects related to the air interface in wireless communications and
supporting technologies, including hardware/software. Activities fall within the
following five general topics:
- Antenna Analysis and Design;
- Wireless Circuits and Devices;
- Waves and Propagation;
- Transmitting and Receiving Systems;
- Radio Networks.
Antenna Analysis And Design
Work on antennas followed three main streams: small-antennas operating at
frequencies typically below 6 GHz for personal terminal integration and for MIMO
systems, antennas for especial applications namely UWB and RFID and millimeter
wave antennas for future Gigabit networks. These activities involved parallel
activity on EM numerical modeling code development and simulation. The work on
antennas has been carried out in the framework of COST Action 284 - Innovative
Antennas for Emerging Terrestrial & Space-based Applications, FCT funded projects
R-Meta project and EBGCOM project, and different contracts with local companies.
Small terminal antennas
Work has continued on the development of new antenna configurations adequate
for laptop PC integration or for integration into small mobile terminals (handsets
and
PDAs).
These
antennas
comply
with
multiple-band
specifications
(ex.
GSM1800, UMTS, IEEE 802.11b/Bluetooth and IEEE 802.11a/HiperLAN2 standards)
and with the possibility of using these antennas with MIMO antenna techniques.
Mutual coupling and correlation have been evaluated having in mind MIMO
applications. The antenna interaction with the user has been studied. Especial
emphasis was given to printed antennas for applications in laptop computers.
A basic MIMO channel sounder was developed based on a Vector Network Analyzer,
for the assessment of antenna design and of its influence on system capacity. The
31
developed channel sounder enables to measure the channel transfer matrix for 2x2
arrays in real scenarios. Work has started on the development of crossexponentially
tapered-slot
antennas,
designed
to
present
very
pure
linear
polarization and low mutual coupling with the other elements from the MIMO array.
Dual-band antenna operation based on geometrically reconfigurable antennas was
explored in the framework of R-META project, using metamaterial substrates to
obtain low-profile antenna configurations.
Antennas were developed in the frame of the EBGCOM project, addressing novel
RF/microwave components based on the EBG technology for applications in
broadband communications.
Other microwave antennas
A new uniplanar compact balanced printed antenna was developed for UWB
applications, with excellent performance for pulsed operation. The antenna can
operate over the full 3.1-10.6 GHz band defined by the FCC UWB standard, and a
modified design was also presented that can include a band rejection to reduce
interference from 5.5 GHz WLAN services without the need of additional filters in
the transceiver.
Another antenna development was for confined RFID tag detection in the UHF band.
A new concept of leaky antenna was developed that allows the antenna to be
embedded and concealed inside furniture (tables, shelves, conveyor belts, etc)
producing confined RFID reading only in especial regions of interest to support the
so called ―intelligent‖ furniture that can replace with advantage of automatism the
manual optical bar code readers in stores.
Millimeter-wave antennas
Activity on millimetre wave antennas was focused on shaped dielectric lens
antennas for applications like the future wireless HD. The emphasis was directed for
a low cost implementation, adequate for mass production. The antenna implements
a new mechanically beam steering concept, and intends to be an early competitor
with less efficient (though more flexible) mm-wave phased arrays.
32
In parallel with these activities, the installation of a 110 GHz measurement upgrade
has continued and is almost finished. This included not only the RF hardware
upgrade, but also software and mechanical structures.
Wireless Circuits And Devices
In this sub-area the research activities can be grouped under three general topics,
one related to RF/microwave circuit design either CMOS based or GaN based,
another to computer aided design of microwave/RF circuits and systems including
simulation techniques and system/device modeling and a third one dedicated to
wireless system design, mainly software defined radio. In all cases, the underlying
applications fall within the wireless area.
RF and Microwave Circuit Design
In this area a low noise down converter (Philips QUBiC4G 0,5um) was tested with
improved figures, like 15dB gain and 14.5dB noise figure at 24GHz. Two active
inductors with voltage controlled inductance were designed with IHP SG25H3
technology, fabricated and tested, figures like L=1nH, and Qs higher than 30 on a
4GHZ band at 30GHz were obtained.
A Voltage Control Oscillator was designed with the new inductor models; in this
case, figures like frequency oscillation from 13 to 17GHz were attained. An accurate
approach to analyze real spiral inductors on silicon MMICs with an EM simulator was
also implemented.
Results were published, related to the study of RF performance of switched
capacitor arrays for use in LC wideband tuning voltage controlled oscillators (VCO).
In that respect, a frequency synthesizer for 2.4GHz applications on 0.35um CMOS
technology was built and characterized.
These approaches were followed in the study of new topologies, design and test of
low voltage MMICs using Si CMOS technology. The developed MMICs were low noise
amplifiers, up converters and phase shift oscillators. Due to the inefficient models
supplied by the MMICs foundries, semiconductor and passive device models are
being developed for CAD programs. Due to the low resistivity of Si substrates,
techniques for experimental characterization of MMICs components and sub-circuits
were studied to support the modeling activity.
33
A first run realization of a 30GHz millimeter wave multifunction MMIC was made
with a CMOS compatible SiGe technology.
Moreover, a strong effort is been put in the design of highly efficient power
amplifiers, as class D and E power amplifiers for WLAN applications on 0.35um
CMOS technology.
These amplifiers can be further integrated into new polar transmitter architectures
this respect, envelope modulator design and its nonlinear impairments to the
overall linearity and efficiency of the system was studied. Pre-distortion techniques
were also employed with very good results that deserved several publications in
conference proceedings and in journals.
A step further was also given in the design of major blocks of a RF front-End
Transceiver design on 0.18um CMOS for WLAN and Bluethooth applications. A
complete synthesizer and a direct-conversion receiver are already available.
Three prototypes of RF-CMOS systems – a VCO, a class-D Power Amplifier and a
LNA – including the power management block, based on hard-switch buck dc-dc
converters, were designed, tested and fabricated. Simulation results based on the
final layout architecture reveal that the electromagnetic interferences between the
RF, power and analog sensitive functional blocks are not critical for system
functionality. The study of design techniques for improved isolation of analog
sensitive blocks was started.
Some work has been also done in space robustness RF electronics, by designing an
oscillator for space applications based on Gallium Nitride (GaN).
Computer Aided Design Tools for RF/Microwave Circuits and Systems
Despite the models already refered above, new development of computer aided
design tools for nonlinear electronic circuits design, telecommunication systems
identification, active device modeling were done.
Beyond these works, research work was also intensified on the design of general
nonlinear behavioral models for telecommunication sub-systems and devices, and
their use in digital pre-distortion linearization.
These new models allow for the development of new approaches to design the
predistorter transfer function for a power amplifier (PA), contributing to the
34
linearization of the signal transmission chain while, for efficiency purposes, the PA
is kept in a nonlinear working region. Based on physical knowledge of the PA
circuitry, PA behavioral models were obtained by nonlinear system identification
processes. The nonlinear dynamic models generated were then used (by means of
theoretical analysis) in the design of optimal predistortion models (or algorithms).
A strong effort was also put in the study and design of input/output buffer
characterization,
within
contributions were
the
given
for
scope
of
the
European
the development
of
Project
MOCHA,
system-level
new
models for
characterization of integrated circuit (IC) I/O Buffers. These new models, mimicking
the nonlinear dynamic behavior of I/O Buffers are suitable to be inserted into Signal
Integrity analysis software in order to evaluate the performance/feasibility of
System-In-Package IC implementation (without the necessity of simulating devicelevel models).
In this respect a modeling strategy was also defined for characterizing the IC power
rail characteristics, with the objective of using such new models (which are lumpedelements' models) inside Signal Integrity analysis software (avoiding the time
consuming distributed models commonly used). The modeling approach was
determined by the evaluation of several sets of measurements taken on on-wafer
flash memory dies, using a probing station.
Wireless System Design
Related to wireless system design an effort was put in the design of software
defined radio RF front ends, that are capable of achieving high bandwidth and high
dynamic range that respect a characterization bench was developed for the
evaluation of the signal quality passing through mixed mode systems, (analog and
digital) and a SDR receiver was characterized is being improved in order to be able
to implement multi-mode multi-standard RF front ends.
Waves and Propagation
Work in this sub-area includes propagation models for body area networks, for
mobile systems and more fundamental work in the area of elctromagnetics of
complex media with possible application to antennas and other relevant devices for
wireless supporting technologies. It also includes studies for EM exposure
assessment.
35
Radiowave Propagation Modelling
Work has started on the development of channel models for Body Area Networks;
Work has been done also on MIMO channel modeling, for different types of indoor
scenarios based on experimental measurements mainly with the objective of
quantifying the influence of antenna mutual coupling.
EM exposure assessment
In line with the public service part of IT mission, the MONIT project continues its
risk communication activity on public exposure to electromagnetic radiation. The
project is sponsored by all Portuguese mobile operators. The project contributes for
public awareness of basic concepts related to electromagnetic radiation and
population exposure in mobile communications through a public website with
measured results from several hundred sites scattered around the Country, through
direct information campaigns in public areas, and through short-courses for nonengineers.
Electromagnetics of Complex Media
One very strong work topic is related to electromagnetics of complex media and
metamaterials, the artificial materials that are obtained by random or periodic
inclusion of metallic or dielectric particles into a host dielectric media to produce
unconventional electromagnetic properties not found in natural materials. These
materials may have application for antennas and other devices for wireless
applications. Work has continued along these lines in EBGCOM and R-META
projects. In the former project, work has progressed in the development and
implementation of novel RF/microwave components based on the electromagnetic
band gap (EBG) technology for applications in broadband communications. In the
R-META project, work has continued on the characterization of artificial ground
planes formed by metamaterials. Artificial materials with extreme index of
refraction were fabricated and tested for waveguiding applications and for
verification of a superlensing effect.
Still related with metamaterials, novel sub-wavelength imaging devices were
studied, formed by nano-rods. Electromagnetic fields at the sub-wavelength scale
were manipulated using materials with near-zero permittivity.

of

waveguides
involving complex media and metamaterials with negative refractive index (NRI)
using a continuous media approach. Work addressed the analysis of surface and
leaky modes in chiral H-guide. Leaky-mode propagation was also studied for NRD
structures. The effect of losses in metamaterial waveguides was also studied.
Numerical methods for electromagnetics
Work continued on the implementation of Maxwell equations in 2D using Sparse
Point Representation (SPR) and PML (Perfectly Matched Layer) as boundary
condition. The method combines high order finite difference schemes with an
adaptive technique based on interpolating wavelets, which leads to sparse grids
that adapt in space to the local smoothness of the fields, while simultaneously
tracking their evolution over time.
This topic is being investigated for the solution of Maxwell equations in collaboration
with the Instituto de Matemática, Estatística e Computação Científica (IMECC) from
the university Unicamp, Brazil, within the framework of a Portuguese/Brazilian
action.
Transmitting and Receiving Systems
Performance studies were carried for HSDPA and HSUPA at 900/2000 MHz bands
and adjacent channel interference in UMTS systems in the 2000 and 2500 MHz
bands. Concerning 3G systems an analysis and optimization study based on drive
tests was also considered.
Work
has
continued
on
pre-processing
schemes
to
achieve
interference
cancellation, combined with Multiple Input Multiple Output (MIMO). Research aimed
at transferring this required signal processing to the Base Station (BS), in order to
reduce the Mobile Station (MS) complexity. It was concluded that, in most
conditions,
the
MIMO
pre-processing
scheme
allows
effective
interference
cancellation and provides diversity, leading to better performance and capacity
coping with the requirements of emerging cellular communication systems.
Other
studies
were
carried
out
on
capacity
enhancement
of
wireless
communications systems using MIMO techniques namely with application for the
Long Term Evolution (LTE) in macrocell scenarios.
37
New research topics were initiated, namely MIMO systems applied to both
Orthogonal Frequency Multiple Access (OFDM) and Single Carrier - Frequency
Domain Equalization (SC-FDE), which are potential technologies to be used in the
fourth generation of cellular systems, currently referenced as (LTE).
Efficient simulation methods were applied for wireless communication systems
using different modulation, coding and fading models with special emphasis on TCH
(Tomlinson, Cercas, Hughes) codes. A new UWB system was developed using TCH
codes for both coding and synchronization aspects. New techniques (namely
hierarchical constellations, channel estimation, MIMO, OFDM) were evaluated for
use in LTE of UMTS systems.
Two WiMAX simulation tools were developed: one is a static tool for fixed WiMAX
and the other a dynamic simulator for mobile WiMAX.
An intelligent web interface is being developed to be used with the new satellite
ground station of IT, located in Lisbon, to allow this station to be used remotely in
academic and research projects.
Radio Networks
Different simulators were developed for the air interface of UMTS-FDD, with HSDPA
and HSUPA, and WiMAX, enabling the analysis of traffic aspects as well as load and
handover ones.
Cellular planning and system capacity optimization studies were carried out for B3G
Mobile Communication Systems in the context of interoperability (HSPA/WiFi with
QoS). This included radio access technology selection algorithm, optimization of the
use of block acknowledgment policies in WiFi, and cross-layer optimization between
PHY and MAC layers for IEEE 802.11e.
Medium Access Control (MAC) protocols and Energy Saving strategies for Wireless
Sensor and Actuator Networks (WSANs) were developed, including aspects of
measurement and data acquisition for health monitoring. Routing algorithms were
developed for cross-layer design of ad-hoc and Wireless Sensor and Actuator
Networks;
38
Another research topic was the development of Radio Resource Management (RRM)
algorithms for virtual mobile communications networks; work also continued on the
development
of CRRM algorithms for heterogeneous mobile communication
systems;
Contributions were given for the topic of planning and deployment of WiMAX and
Terrestrial Digital Television Networks (TDT), including analytical, experimental and
simulation/planning approaches.

A generic radio channel model for propagation in inhomogeneous forests
at 40 GHz
Funding
FCT/POSC
Descript.
This proposal aims to take forward the RET modelling work carried out
by the Principal Investigator (PI) under a UK consortium, which
identified a number of problems in the estimation and establishment of
the input parameters required by the RET model. In addition, this
research intends to investigate current approaches and develop new
more accurate narrow and wideband channel models through theoretical
investigations as well as experimental data gathering at 40 GHz in view
of BFWA applications. The influence of inhomogeneous vegetation in a
cluttered environment with respect to their influence and the radio
propagation path as well as their potential origin of interference within
networks and onto other networks will be addressed in this program.
Both narrow and wideband channel performances and fast fading
dynamics of signals propagating through, around or scattered from
vegetation will be modelled and included in the prediction tool, as these
are critical for quality of service, RF regulation and the assessment of
spectrum efficiency.

ASPIRE
Advanced Sensors and lightweight Programmable middleware for
Innovative Rfid Enterprise applications
Funding
EU, FP7
Descript.
ASPIRE will research and provide a radical change in the current RFID
deployment paradigm through innovative, programmable, royalty-free
and privacy friendly middleware. This new middleware paradigm will be
particular
beneficial
to
European
SME,
which
are
nowadays
experiencing significant cost-barriers to RFID deployment.
43
European networked enterprises in general and SME in particular are
still reluctant to adopt RFID, since they perceive RFID as unprofitable
or too risky. This is largely due to the fact that the adoption of RFID
technology incurs a significant Total Cost of Ownership (TCO). ASPIRE
will significantly lower SME entry costs for RFID technology, through
developing
and
providing
a lightweight, royalty-free, innovative,
programmable, privacy friendly, middleware platform that will facilitate
low-cost development and deployment of innovative RFID solutions.
This platform will act as a main vehicle for realizing the proposed swift
in the current RFID deployment paradigm. The ASPIRE middleware
platform will take into account innovative European developments in
the area of ubiquitous RFID-based sensing (i.e.,physical quantities
sensing
(temperature,
humidity,
pressure,
acceleration),
mobile
sensing) towards enabling novel business cases that ensure high ROI
(Return on Investment). The ASPIRE RFID middleware paradigm, as
well as the unique and novel characteristics of the ASPIRE middleware
platforms are thoroughly described in this proposal.

Title
Architecture and Design for the Future Internet
Funding
EU-FP7 ICT
Descript.
Today‘s network architectures are stifling innovation, restricting it mostly
to the application level while the need for structural change is
increasingly evident. The absence of adequate facilities to design,
optimize and interoperate new networks currently forces a convergence
to an architecture that is suboptimal for many applications and that
cannot support innovations within itself, the Internet. 4WARD overcomes
this impasse through a set of radical architectural approaches built on
our strong mobile and wireless background.
We improve our ability to design inter-operable and complementary
families of network architectures. We enable the co-existence of multiple
networks on common platforms through carrier-grade virtualization for
networking resources.
44
We enhance the utility of networks by making them self-managing. We
increase their robustness and efficiency by leveraging diversity. Finally
we improve application support by a new information-centric paradigm in
place of the old host-centric approach. These solutions will embrace the
full range of technologies, from fibre backbones to wireless and sensor
networks. The 4WARD results will allow new markets to appear,
redefining business roles and creating new economic models. We will
establish the Future Internet Forum as a leading standards body,
enabling these new markets and opening them for old and new players
alike, increasing opportunities for competition and cooperation and
creating new products and services. These goals can only be achieved by
gathering a strong, industry-led consortium of the leading operators,
vendors, SME, and research organisations, with the determination, skills,
and critical mass to create cross-industry consensus and to drive
standardisation. The project is designed for multiple phases; the first one
will establish the core concepts and technologies and last for two years.
The planned effort of about 2200 person months corresponds to the
strategic importance of this endeavour.

Title
Cross-Layer Design and Network Planning for B3G Systems
Funding
FCT/POSC
Descript.
After 3G mobile and wireless systems take-up, the research community
is now directing its interest towards unified ways of looking at system
design, optimisation, and QoS issues to satisfy the requirements of next
48
generation multi-service mobile and wireless IP-based networks.
Their implementation requires the development of IP QoS architectures
and mechanisms encompassing the various layers of the OSI Model to
cope with the new requirements. The basic idea to be pursued in this
project is that QoS provision in wireless networks, will require the joint
collaboration among physical, MAC, IP and transport layers; how it may
be done, and new definitions of cross-layer protocols are thus important
areas for collaborative studying and research.
As these multimedia communications systems will be wide- and
broadband (with data rates much higher than 3G ones), multi-service,
and multirate
ones, the QoS provision for each service (within different traffic classes),
and the identification of suitable schemes to guarantee high
capacity in these heterogeneous environments are also of particular
concern in this project.
To achieve these goals the project is divided into three main areas:
- Traffic modelling and QoS, where traffic models appropriate to
characterise the different classes of services envisioned for B3G systems
are
studied. Characterisation parameters and traffic models that accounts
for multi-rate applications will be used as an input of the design and
optimisation process.
- MAC definition and cross-layer design, where the use of the traffic
model
results,
and
proposals
for
architectures
using
cross-layer
information
(CLI) to achieve QoS are investigated and assessed. Research work will
include the identification and transport of relevant cross-layer
information (CLI), the definition of a cross-layer (CL) architecture
framework, and Cross-layer strategies between PHY and MAC/RRM.
- Network planning and optimisation, which represents the synthesis
and integration of the two previous activities by means of performance
49
evaluation (including simulation). Multi-service deployment scenarios,
with
simultaneous
support
of
multi-rate
multimedia
applications,

Two current trends in wireless communications are the development of

wireless networks, to achieve the vision f the so-called 4G network.
The FUTON project addresses both issues by proposing the development
of a hybrid fibre-radio infrastructure transparently connecting remote
antenna units to a central unit where a joint processing can be
performed. This allows the development of virtual multiple antenna
transmission / reception concepts to achieve broadband wireless
transmission, and also inter-cell interference cancellation. Furthermore
the fact that the management of several heterogeneous systems is colocalized enables the development of efficient procedures for a joint
management of the radio resources.
The focus of the project aims to develop and validate a hybrid opticalradio infrastructure, where simplified Remote Antenna Units (RAU) are

Large Signal Measurements for Nonlinear Behavioral Model Extraction
Funding
CRUP
Descript.
With the recent advances on Wireless Communication Systems, the
spectrum occupancy has rise severely. This imposes a very restringing
limit on the modulation formats that should be used. As is well known,
higher values of spectrum efficiency imposes modulation formats of nonconstant amplitude, which are very demanding in terms of linearity of
Power Amplifiers, PA. In order to account for these nonlinear effects on
wireless communications, proper CAD/CAE tools should be used. But in
order to predict all the relevant information of a system with CAD tools,
some improved models describing the system behaviour should be used.
Those models could be divided into three types, physical (completely
physical based model), empirical (based on some physical knowledge,
but less complex that the physical solution) and completely behavioural
model based on input/output relations (in this case the device under
test is considered a black box).
Due to the fact that wireless systems have being more and more
complex, and thus includes a higher amount of components, the
simulation of those systems, had moved to (from?) the so called base
equivalent models, and thus to the complete behavioural model
description of components. Nevertheless if this is easily obtained for
linear components, it is more difficult for nonlinear ones. That is the
reason why a large amount of researchers are looking to this
behavioural model scientific area. But as in all modelling activities the
model process is not completed without a precise measuring of certain
parameters, in order to be able to extract the model parameters.
This project will be devoted mainly to this measuring approach, and thus
to the instrumentation needs for a certain behavioural model parameter
extraction. In that respect new approaches to the measuring of
amplitude and phase is fundamental, and this should be done in the
presence of complex forms of input signals, including the well know one-
60
tone sinusoidal input, two-tone, and more recently multi-sine schemes.

Summary of Research Achievements
In the following, the achievements in the Optical Communications area are
grouped, under three sub-areas:
- Optical Components and Subsystems
- Optical Communication Systems
- Optical Networking.
Optical Components and Subsystems
The work carried out in this sub-area concentrated on the modeling, performance
evaluation, optimization and implementation of key components and subsystems
for all-optical networks.
TMM based threshold models were used to optimize several non-conventional DFB
structures. The method was extended to deal with structures with longitudinal
variations in their grating pitch, generally known as corrugation-pitch modulated
(CPM)-DFB laser diodes. Above-threshold calculations of several stationary laser
characteristics have confirmed the optimization procedures.
The investigation of frequency response of semiconductor PIN photodiodes for
optical communications continued. The effect of temperature on the transit time
limited frequency response was considered by using a previously developed
numerical model, which may be applied to devices with arbitrary electric field
profile in the absorption region and non-uniform illumination. It was seen that an
increase of temperature decreases the drift velocity and increases the absorption
coefficient. Both effects lead to a decrease of the photodiode‘s bandwidth.
Furthermore, it seems that the device‘s bandwidth is more sensitive to temperature
for lower reverse bias voltage.
Research on linear applications of quantum dot semiconductor optical amplifiers
(QD-SOAs) was pursued, namely on wavelength conversion and optical logic
devices. The development of a simulator for the OSSB transmitter to be used in the
demonstrator of project RoFnet (FCT) was concluded.
109
In the area of quantum communications, the four-wave mixing process was
explored in a low power regime to generate single photons and entangled photon
pairs to implement quantum secure communications protocols. The four-wave
mixing process in a low power regime was studied both theoretically and
experimentally. The coupled-equations for the complex amplitudes were derived
and solved. The proposed model was compared with experimental data. Results
show the need of considering both nonlinear and polarization dependent effects in
order to obtain an accurate description of the four-wave mixing process in a low
power regime.
In the area of integrated optics, passive devices (Y-branch splitter) for passive
optical networks, based on sol-gel technologies have been developed.
A new prototype for tuneable dispersion compensation was developed. The
prototype uses a novel technique based on function weighing for continuous and
immediate tuneable operation. The technique is patent pending and can be used for
other devices such as tuneable pulse shapers or tuneable polarization mode
compensators. Operation at 40 Gbit/s was demonstrated, while operation at 160
Gbit/s is also being addressed. A new RF frequency meter was developed for
frequencies up to 60 GHz. It is based on an optical interferometer and has an error
lower than 100 MHz. It can also be adapted for higher bandwidths and lower errors.
A new method for the production of tuneable chirped FBG was developed. It is
based on tapered fibres and can also be used in multi-parameter sensors. The
method is patent pending.
An analytical approximated solution for the gain of broadband Raman amplifiers
with multiple counter-pumps was proposed. The transient effect in pump reflecting
Raman fiber amplifiers was analyzed. In order to better understand the impact of
reflecting the unused pump power in the amplifier behavior, several scenarios were
investigated. Results show that this pumping scheme has a worse response to
dynamic channel add/drop. However, a pump-controlled gain-locked system able to
mitigate the amplifier transient response was proposed. Following this approach, an
110
efficient low cost Raman fiber amplifier suitable for dynamic optical networks was
obtained.
An integrated optical transmitter with applications in radio over fiber subcarriermultiplexed systems employing direct detection was investigated. The transmitter
combines a highly linear carrier suppressed signal with an optical carrier. Optical
and electrical carrier to interference ratio (CIR), and error vector magnitude (EVM)
measurements were carried out for the proposed and a conventional transmitters.
Improvements of up to 19.9 and 16 dB of optical and electrical CIR, respectively,
were obtained. The EVM is reduced from 4.2 to 3.5 %.
Optical Communication Systems
Several advanced modulation formats for optical fibre communication systems were
investigated.
A
novel
wavelength-division
signaling
multiplexed
format
optimized
(UDWDM)
systems
for
long-haul
was
ultra-dense
proposed
and
its
performance compared with other recommended direct-detection formats and with
the bandwidth-limited differential phase shift keying, showing similar or better
performance than those formats. A novel semi-analytical method for bit error ratio
(BER) evaluation in simulated optical DQPSK systems was proposed. The upgrade
of metropolitan area networks to 40 Gbit/s per channel using DQPSK signals was
analyzed.
3R all-optical regenerator work was pursued. An experimental study of patternindependent phase noise accumulation in an all-optical clock recovery chain based
on two-section gain-coupled DFB lasers has been performed. A method for bit error
ratio analysis of a chain of 3R all-optical regenerators taking into account the
optical noise and timing jitter has been proposed.
Directly modulated transmission systems were also investigated. Guidelines for
laser optimization in dispersion supported transmission systems operating at
arbitrary bit rates were proposed.
111
Analysis of the impact of cross-phase modulation (XPM) on the performance of
dispersion managed dense WDM systems was continued. The influence of the
channel number on the optimal dispersion map due to XPM in wavelength-division
multiplexed (WDM) links was investigated.
Optical distribution of orthogonal frequency division multiplexing (OFDM) and
impulse-radio (IR) ultra-wideband (UWB) radio signals in fibre-to-the-home (FTTH)
networks was proposed. The experimental comparison of transmission performance
of multi-channel OFDM-UWB signals on FTTH networks was performed. The
performance degradation due to OFDM-UWB radio signal transmission along
dispersive single-mode fiber was investigated. The influence of the dispersioninduced power fading on the fiber transmission performance of OFDM-UWB radio
signals was assessed. The impact of aliasing and inter-channel interference on the
performance of multi-channel OFDM-UWB distribution in FTTH networks was also
investigated. The influence of pilot tone-assisted equalization in Wimedia-defined
OFDM-UWB signals transmission in FTTH networks was assessed. The management
of UWB picocell clusters using the UCELLS project approach was presented. Several
contributions for the photonic analog-to-digital converter structure investigated in
the UCELLS project in order to realize the spectrum management were proposed.
The use of return-to-zero formats to enhance the dispersion tolerance of intensitymodulated carrier-unsuppressed (IM-CUs) optical single sideband (oSSB) systems
was
investigated.
The
performance
of
these
systems,
employing
electrical
dispersion compensation (EDC) was investigated using unipolar and polar RZ
signaling formats, and compared with common non-return-to-zero (NRZ). It was
concluded that the use of polar RZ allows increases extinction ratio and
transmission distances, because of higher inter-symbol interference tolerance and
the absence of discrete spectral tones. Considering a minimum ER of 9 dB and
resort to forward error correction schemes, polar RZ allows single-channel error
free transmission over 1400 km of standard single mode fibre, a substantial
improvement over the 980 km obtained for NRZ with ER of 6 dB. Dense wavelength
division multiplexing transmission was also assessed, showing improved resilience
of IM-CUs oSSB polar RZ.
112
Optical Networking
Research has continued on the topic of Passive Optical Networks (PON). An
important contribution to the standardization of 10G-EPONs by IEEE has been
made. Work focused on the implementation of a management model for a Gbitcapable passive optical network (GPON) was concluded. Research on next
generation PONs included improvement of the access network performance and
capacity by introducing FEC, burst-mode power equalization, a new paradigm for all
optical access networks with active remote nodes, and new CDMA codes and
modulation techniques. Work on the use of Raman amplification in metropolitan
and access networks was concluded.
Work on optical burst-switched networks continued in 2008. The strategy
developed in the previous year to minimize the wavelengths contention by
combining the HMPI (Heuristic Minimum Priority Interference) algorithm with an
appropriate
burst
scheduling
at
the
ingress
nodes
was
consolidated.
The
performance of this strategy as a function of different network parameters was
exhaustively evaluated, and the results obtained confirmed its advantage in
comparison with published strategies.
Work on transporting 100 Gbit Ethernet traffic over OTN (Optical Transport
Network) networks was pursued. Diverse ILP (Integer Linear Programming) and
heuristic formulations were developed taking into account aspects like virtual
concatenation, multipath routing, and differential delay minimization.
Work on protection in optical networks has continued. Expressions were derived for
estimating the extra capacity required for dedicated protection in optical networks.
For
ring
topologies,
expressions
are
exact
and,
for
mesh
topologies,
an
approximation was obtained. Results show that the protection capacity can be
estimated without the complete knowledge of the network topology. Moreover, we
found that the dependence on the demand model is negligible, for estimation
purposes.
113
Investigation on routing and wavelength assignment in transparent optical
networks
impaired
by
physical
effects
continued.
An
efficient
wavelength
assignment policy for XPM-impaired WDM networks was proposed.
Further efforts have been made into the FTTX field. We have been engaged in
several related projects and activities in the field of quasi passive networks networks that allow full passiveness and simultaneously an added advantage of
being able to reconfigure - have resulted in several publications. Also, in FTTX, one
major limitation is the monitoring of the physical structure, and several techniques
have been analyzed. In order to take full advantage of this, studies on cross layer
issues have been made.
In the areas of modulation and high power in optical networks, we have been
studying modulation formats that are able to provide re-modulation as well as the
combined effects of multiple type of remote amplification (Raman + EDFA). Studies
have also been carried out on the limitations of power inside fibers.

Title
Dimensioning of Multi-Layer Optical Networks
Funding
AdI
Descript.
Modern transport networks make use of transmission in the optical
domain and perform the routing in the electric domain. The emergence
of devices with routing capabilities in the optical domain creates a new
paradigm.
In principle, this new paradigm can increase the networks throughput
and reduce the infra-structure costs. The present challenge is to
understand how these optical routing modules should be integrated in
the
networks
to
obtain
more
flexible
telecommunication
infra-
structures, with minimum cost of installation, maintenance and
management.
These optical routing modules also induce transient effects in the
network that is essential to understand and control.
We
intend
to
treat
the
dimensioning
problem
with
probabilistic/statistics models in detriment of the deterministic models
approaches. We intend to obtain simple causal relationships between
critical aspects in the dimensioning problem and to obtain results with
a high degree of confidence with less computational time.
We are going to focus our research on Multi-Layer Survivable Optical
Networks with optical and electric routing, supported by multiple
wavelengths (WDM) optical transmission systems and optimized for IP
traffic.

Next Generation Passive Optical Networks

Descript.
Passive optical networks (PONs) have evolved to provide much higher
bandwidth in the access network, attracting therefore significant
interest from both standardization organizations (ITU-T and IEEE) as
well as industry and service providers. PON technology is recognized
as the most economical solution for the introduction of optical fibre in
the access network, stimulated by the need to increase the bandwidth
offered to subscribers, matching it with the transport capacity of
metropolitan networks.
Although the PON systems provides higher bandwidth than traditional
copper based access networks, there is a growing demand for further
bandwidth
increase
through
application
of
wavelength
division
multiplexing (WDM). This way several parallel data channels can be
employed in downstream and/or upstream direction. Additionally, data
security issues arising from Point-To-Multipoint architecture with
inherent broadcast nature of the downstream channel require closer
analysis of the potential threats and means of mitigation utilizing e.g.
active
countermeasures
against
malicious
activities
through
identification and isolation of suspicious ONUs It is our goal therefore
to analyze in detail (theoretically and practically) the transition process

Title
Optimized Transponders for Robust NETworks
Funding
AdI, Siemens Networks SA
Descript.
The explosive growth of data, particularly internet traffic, has led to a
dramatic increase in demand for transmission bandwidth imposing an
immediate requirement for broadband networks. Currently core
networks widely employ WDM to offer high capacity and long reach
transmission capabilities. WDM has recently started becoming a very
attractive technology also for metropolitan area networks where the
major requirement is cost-efficiency. A real catalyst motivating the use
of WDM in MANs is its promise of transparency offering elimination of
opto-electronic regenerations. In both network segments the use of
transparent solutions introduces impairments penalizing the system
performance. These impairments can be significantly suppressed using
purposely designed and optimized systems incorporating advanced
modulation formats and equalization techniques that assure that the
signal performance remains adequate under worst case conditions.
The OPTRONET consortium proposes work that will result in the
development of such systems and will enable the deployment of costand
performance-
optimized
transparent
optical
metropolitan
networks.
The partners of the project will design, evaluate, develop and
demonstrate novel metro-specific transceiver prototypes. A variety of
modulation formats offering great potential for optimized metro
networks will be the focus of the project. The option of electronic
channel equalization and the performance improvement that it offers
will be studied in detail. The different systems will be assessed for
technical and manufacturing feasibility, improved system/network
performance and customer value. Effort will be assigned in low cost
solutions tailored to metro requirements. Simulations will analyze the
performance of the systems in a reference WDM metro network, and
will determine the optimum implementations for the variety of
118
modulation formats and equalization techniques. Consequently novel
transmitters based on advanced modulation formats and receivers
offering dynamic signal equalization will be designed and fabricated.
The developed systems will be evaluated in laboratory test-beds. In
order to verify the proposed solutions a field trial will be performed
using real metropolitan networks delivering different types of highbandwidth services to end-users. The aim of the project is to provide
guidelines on technology choices, to define the requirements for
optical interfaces and develop advanced transceiver systems in order
to meet user as well as operator requirements towards broadband
metropolitan topologies.

Title
Towards digital optical communications
Funding
ESF
Descript.
The primary objective of the COST Action ―Towards Digital Optical
Networks‖ is to focus on novel network concepts and architectures
exploiting the features and properties of photonic technologies, to
enable future telecommunications networks. It is aiming to propose a
119
new generation of systems and networks that will accommodate the
unpredictable and growing size of data files and messages exchanged
and stored as well as real time services (e.g. voice, video etc) over
global distances requiring an agile Communication Grid supporting
quality of services. These need to provide end-toend bandwidth for
transmission of traffic for applications such as information retrieval,
downloading (often multimedia) web software, exchange of various
type of software (hundreds of Mbytes) and data models (Gbytes) etc
as well as real time multimedia applications.
These systems need to be very flexible and rapidly reactive to
efficiently accommodate the abrupt and unpredictable changes in
traffic statistics introduced by current and future applications with low
endto- end latency. They will enable advanced features such as
efficient and simple multicasting and broadcasting of broadband
signals. In general, they need to support a future proof, flexible,
efficient and bandwidth-abundant fiber-optic network infrastructure
capable of supporting ubiquitous services in a resilient manner offering
protection and restoration capabilities as well as secure services to the
users.
Transparency to various digital signals and protocols is required to
eliminate the need for multilayer complex network architectures
suffering
by
poor
scalability
for
data
services,
high
latency,
complicated network management and high cost. This migration can
be gradually achieved by removing and/or integrating intermediate
layers.
Flat
and
upgradeable
network
architectures
supporting
photonic core and access technologies with intelligent edge nodes at
the interfaces will form a universal infrastructure offering a variety of
services supported by multiple operators. The ease of maintenance,
provisioning and resilient operation required in this type of networks
will
be
achieved
through
advanced
routing
and
management
mechanisms, eliminating the requirement for ever increasing amounts
of complex software raising the cost and limiting the network reliability
and availability.
120
This advanced photonic infrastructure will employ optical signal
processing and dynamic impairment management to eliminate the
limitations of the analogue nature of traditional optical networks,
dense
wavelength
division
multiplexing
technologies
for
signal
transmission and routing, and optical packet and/or burst switching to
provide fine bandwidth granularity, network efficiency and flexibility.

4.3.3
The work in the area of Networks and Multimedia is organized in several topics:
- Architectures and protocols;
- Security and quantum information;
- Traffic engineering;
- Network operations, management, and planning;
- Network applications and services
- Processing, analysis and coding of audio and visual information;
- Pattern recognition and automatic learning;
In the following, we briefly summarize the main achievements in each of
these topics.
Architectures And Protocols
Mathematical foundations of Internet routing – We have defined the concept
of local routing as an abstraction that encompasses the highest level of the routing
decision processes in the Internet. We pursued a comprehensive investigation of
local routing, presenting conditions for correctness of a reachability-vector protocol,
studying its complexity, comparing its performance with that of shortest-path
routing, and, most importantly, showing why and by how much it constrains the
intrinsic connectivity of a network. The insights learnt from the model of local
routing were applied back to its instantiations in inter-domain routing and route
redistribution in enterprise networks. We estimated the loss in connectivity of the
Internet arising from the pairwise, commercial nature of the relationships
established between Internet domains and we provided a guideline for the
configuration of the border routers of enterprise networks that both guarantees a
correct operational behavior and maximizes the usable connectivity of the network.
The results of this work have been submitted for possible publication.
162
Pros and cons of network coding – We made a critical comparison of network
coding and routing protocols from the point of view of a system designer in the
layered networking architecture. Network coding protocols offer clear advantages in
terms of throughput and robustness for highly volatile networks such as wireless
ad-hoc networks and peer-to-peer communications. It is not likely that network
coding will find its way at the routing layer of the current internet protocol stack.
Informed network coding for minimum delay - Since network coded
information can only be recovered after delivering a sufficient number of coded
packets, the resulting decoding delay can become problematic for delay-sensitive
applications such as real-time media streaming. Motivated by this observation, we
consider several algorithms that minimize the decoding delay and analyze their
performance by means of simulation. The algorithms differ both in the required
information about the state of the neighbors‘ buffers and in the way this knowledge
is used to decide which packets to combine through coding operations. Our results
show that a greedy algorithm, whose encodings maximize the number of nodes at
which a coded packet is immediately decodable significantly outperforms existing
network coding protocols. Joint work with NTT DoCoMo Eurolabs.
Information dissemination with network coding - Information dissemination
in communication networks is a key function whose effectiveness depends both on
the chosen dissemination algorithm and on the underlying network topology. A
series of contributions in statistical physics has uncovered the specific topological
properties of small-world networks that potentiate the spread of information, most
strikingly small network diameters and large clustering coefficients. Simultaneously,
the spectra of dissemination algorithms, typically based on message replication,
was recently enlarged by the advent of the network coding paradigm, in which
intermediate nodes are allowed to mix information flows through non-trivial linear
operations.
Intrigued
by
the
dissemination
of
information
in
broadcast
environments with small-world topologies, we compare the behavior of competing
replication based algorithms and their network coding counterparts. We show, both
analytically and through simulation, that network coding requires a smaller number
of transmissions and shorter propagation delays, conjugated with impressive
steadiness under distinct topological configurations.
163
Connectivity in vehicular ad-hoc networks - Motivated by the recent surge in
vehicular ad-hoc network (VANET) research and the promise of high-impact
applications such as safety, navigation and infotainment services, we consider the
impact of mobility mis-modelling on the design and development of this class of
distributed systems. Focusing on urban environments, we use a state-of-the-art car
traffic simulator to extract some of the key connectivity metrics relevant for the
design of a vehicle-to-vehicle traffic information system. We compare such metrics
against those obtained from popular mobility models, such as the random waypoint
model and the Manhattan mobility model. Our results reveal striking differences in
the connectivity profile of the network, thus casting some doubt on the adequacy of
simple mobility models for the development of future VANET protocols. Joint work
with Hugo Conceição and Michel Ferreira.
Transport architectures for satellite networks – Phase 2 of project TOP,
dealing with the study of algorithms for TCP congestion control appropriate for
DVB-RCS satellite network environments, was completed successfully during 2008.
This phase dealt with the implementation and test of the algorithm developed in
Phase 1. The work performed in 2008 consisted of further refinement of the test
plan towards the performance evaluation of a prototype implementation, followed
by a measurement campaign performed at the ESA-ESRIN site (Frascati, Italy) site
using an Eutelsat DVB-RCS satellite link.
Improved TCP functionalities - We developed a TCP-level name system for
handling name-based TCP connections. Names are arbitrary byte arrays that are
bound to listening ports. Name resolutions take place during the TCP three-way
handshake, not requiring extra message exchanges. The new TCP handshake
conforms
with
the
standard
and
is
fully
compatible
with
existing
TCP
implementations. Among the many opportunities created by the name service, it
allows services with unusual names, known only by small communities, to remain
undetected by port scanners (though not by network sniffers).
Wireless LANs - We improved the previous work on bidirectional data exchanges
within 802.11 wireless networks and we defined an opportunistic medium access
protocol that resembles PCF (Point Coordination Function). However, this new
164
protocol starts exactly when necessary, unlike PCF, and uses the medium more
efficiently, since all stations have something to send or to receive when it starts.
New architectural approaches for optical burst switching networks based
on a common control channel - A new architectural approach for optical burst
switching networks was proposed, which is based on a common control channel and
a node locally maintained network model. The common control channel allows for a
fast and efficient broadcast of the network control packets, which in turn are used
by every node to update its local network model. The local network model allows
efficient network resource planning as each node is aware of the reservation status
intentions for the resources on each node. It was shown that the proposed common
control channel OBS (C3-OBS) architecture leads to a better network performance
than conventional architectures.
Wireless
ad-hoc
and
mesh
networks
-
Mobility
between
ad-hoc
and
infrastructure networks, through the help of 802.21 Media Independent Handovers,
is being addressed, and a demonstrator is being built to demonstrate its feasibility.
Work has been done on Wireless mesh networks on the community-oriented
architecture, from the physical layer to the application layer, in which the selforganization mechanisms apply in a general way to the communities‘ concept. In
this sense, the communication between several nodes requires a cross-layer
interaction and agreements between different types of communities. Management
concepts applicable to such an environment are being developed. Optimizations to
mobility on wireless mesh networks are also being proposed and evaluated in ns-2.
A test and measuring open infrastructure, able to assess mesh networks
environments, is being deployed inside IT-Aveiro.
Wireless ad-hoc and mesh networks - GEMS continued its cooperation with IT's
Group for Research On Wireless (GROW) and Heterogeneous Network Research
Group (HNG) in the context of an FP6-IST WIP (An All-Wireless Mobile Network
Architecture) project in which IT participates with both Lisbon and Aveiro groups. In
this project, we finished our work on the discovery of Communities and User
Services. In this project, GEMS delivered the WIP Service Discovery module - WIPSD - to the project, namely to the HNG which as integrated in the Community
Management Framework under development by HNG in Aveiro. The work resulted
in a small test-bed used to carry out part of the performance analysis, being the
large scale scenario results obtained through simulations. These results were
165
submitted to publication in the Elsevier's Ad Hoc Networks Journal and are under
revision after a first peer-revision round by the Journal's referees. Still in the the
Mesh networking area, two internal project involving the use of IEEE802.16- WiMAX
technology were finalized. One of the projects is a test and measurement's tool for
WiMax systems whereas the second entailed the development of flexible QoS
management mechanisms for a heterogeneous test-bed, integrating wireless
(802.16, 802.11) and wired (fast and gigabit Ethernet) technologies; the prototype
was able to run real QoS-aware applications with interesting results. Finally, the
group has undertake a significant effort on the Home Networking area through the
development of a distributed middleware architecture for applications and devices
to seamlessly interoperate and capable of creating an automated home solution
with
service
discovery
facilities
covering
the
entertainment,
security,
communications and automation aspects and coping with the self-organization,
integration
and
user-friendliness
requirements
that
are
typical
of
such
environments. This project has been funded by LEMe as a result of an internal LEMe
project contest.
Sensor networks for healthcare – In area of sensor networks we proposed a
mobile solution that draws on three-tier body sensor networks to dramatically
improve data accessibility, through the use of a Java and Bluetooth-enabled mobile
phone. We also surveyed on the application of wireless sensor networks to
healthcare promotion, namely with the use of biosensor technology applied to body
sensor networks. A study on three simulation tools for Wireless Sensor Networks
(WSNs): Network Simulator 2 (ns-2), Java Simulator (J-Sim) and Sensor Network
Emulator and Simulator (SENSE), was also presented. We also proposed a Guided
User Interface for J-Sim simulator, oriented for simulating Wireless Sensor
Networks, that dramatically increases the user-friendliness of the simulator.
Wireless sensor networks - Wireless Sensor Networks GEMS continued its
efforts, being particularly active, in this area. As a whole, GEMS has been involved
in 6 projects. Regarding our participation in NEWCOM ++ (Network of Excellence in
Wireless Communications), a NoE FP7-IST Project addressing research problems in
the field of wireless networks, namely the challenges posed by ubiquitous network
infrastructure and architectures, our group has been particular active in one of the
166
technical work-packages (WP11) of the project, which started in 1/2008. In WP11 Opportunistic Networks - the pervasive communication scenarios, where delaytolerant applications are expected to play and important role, are the main targets.
Opportunistic networks exploit human (and/or machine) mobility and local
forwarding in order to distribute data. Information can be stored and passed, taking
advantage of node‘s mobility, or forwarded over a wireless link when an appropriate
contact is met. As for the projects that started in previous years, we continue to
work on self-configuration issues and mobility aspects of WSN in application
scenarios where intermittent communications is a key issue. Furthermore, the effort
on specific applications of WSN involving interesting
engineering problems
continued throughout 2008, while a consolidation of the work on the campus WSN
test-bed (called Tagus-SensorNet) has been carried out in 2008. The platform has
been evolving since its deployment in 2007 and gave rise to interesting
experiments and research work. Some results were shared with the scientific
community through a paper describing the development and deployment of the
Tagus-SensorNet; this paper has been extended and submitted to the International
Journal of Sensor Networks (IJSNet). Finally, concerning the 3 projects that started
in 2008, one is related with the development of a new sensor node hardware which
will allow us not only to have domain on the software part of WSN, but also on the
hardware part and, in particular, on the HW-level aspects of energy management;
this is a natural evolution of the group's hardware area from where several sensor
boards (3 presently) have emerged in the last 3 years. The other project is just in
its toddler age and is addressing routing and organization mechanisms specially
tailored to opportunistic networks. The third and last project concerns to the
operation and maintenance problems of WSNs, having the group started an internal
project - Modulus - involving the design and development of a new WSN's
middleware capable of ease the setup and maintenance (and beyond) of complex
WSN applications.
Wireless access networks - The IEEE 802.16 standard represents the state-ofthe-art in technology for metropolitan area broadband wireless access networks.
The point-to-multipoint (PMP) mode of IEEE 802.16 has been designed to enable
quality of service (QoS) in operator-controlled networks and, thus, is foreseen to
complement existing third generation cellular networks. In contrast, the optional
mesh mode of operation in IEEE 802.16 enables the setup of self-organizing
167
wireless multi-hop mesh networks. A distinguishing characteristic of the IEEE
802.16 standard is its support for QoS at the MAC layer. However, the QoS
specifications and mechanisms for the PMP and the mesh mode are not consistent.
Research has been performed to integrate a novel QoS architecture in order to
enhance the IEEE 802.16 mesh mode of operation. In particular, we have evaluated
scheduling algorithms and admission control mechanisms, and the tradeoffs
involved when implementing such mechanisms in 802.16 mesh mode, focusing on
the efficient management of the available bandwidth resources. In order to
evaluate and validate the performance of the developed mechanisms, a simulation
study is being developed, based on the NS2 and NCTUS simulation tools.
Multimedia communication architectures and protocols - It was developed an
integrated IMS-MBMS layered framework, which is inline with the existing
standards frameworks and architectures and offers a complete end-to-end design
allowing interactive mobile TV services and Web 2.0 content to be distributed in an
efficient way within mobile communities. The BM-SC (Broadcast Multicast Service
Centre) functionalities were spread over an enhanced IMS architecture in order to
support multicast bearers. Based on the evolved system, a complete signaling was
developed allowing IMS users to distribute multimedia content to groups of users
over
unicast,
multicast
and
broadcast
bearers.
This
information
could
be
customized in fucntion of the overall context. To manage the data generated by the
several sources, enterprises and end-users, it was defined a Content Information
Inventory (content and file detail and useful data) and a Metadata Protocol Schema
Definition (XML Schema) used to organize content information. It was also defined
the most suitable protocol to transfer data from the content provider to the
operator, or service provider, and the most appropriate content format for upload
and streaming.
Home networks and residential gateways – The specification, implementation
and demonstration of a solution for e-Care services based on the results of the
previous project IST@Home proves the concept of this tele-care innovative
solution. It includes different pieces needed for this complete pack of services (e.g.
emergency/panic
alarm,
video-telephony,
remembers,
medical
vital
signs
measurements): e-Care Service Centre with SQL database and several operator‘s
positions, OSGi Service Centre enabling the life-cycle full control of each service
168
available in each client, OSGi enabled Home Gateway with QoS for the LAN and
WAN sides, and IP terminals connected through several different broadband LAN
technologies. Additional requirements/features have been added to this OSGi
enabled Home Gateway due to our participation in MUSE project, namely an EAP
authentication process using IEEE 802.1X standard. Some indicators about the
value chain of the new home and SOHO services have been obtained in OSIAN
project, allowing one more clear picture of the possible Telco revenues. Integrated
on last year projects of LEET degree some research and developments have been
made on no-intrusive tele-surveillance associated also to movement detectors.
Several alternatives to the UTPcat5e structured network were tested (e.g. PLC, WiFi, HPNA), namely the newest 200Mbps DS2 PLC solution with the direct support
from the manufacture, allowing a deep knowledge of this technology. These results
were integrated and presented in a PT Inovação internal project, enabling the
collaboration in the initial specification for the PTCom commercial Triple-Play
deployment.
Heterogeneous
networking
issues
-
Research
is
being
performed
in
heterogeneous networks, focused on the evolution towards fixed and mobile,
convergent, next generation architectures. This work covered areas of: QoS support
across different technologies and networks (infrastructure and ad-hoc) and over
different administrative domains; ad-hoc and moving network environments
integrated in the common architecture; mixed mobility types with QoS integration
and mobility management in multi-access environments, using IEEE 802.21 to
support media independent handovers, and mechanisms for intelligent handover
decisions commonly performed by the user and network (specific technologies
supported: Ethernet, 802.11, 802.16 and DVB); multicast communications with
QoS and mobility; mobility of both mobility of the listeners and of the sources in
multicast environments, where the movement of sources is made transparent to
the receivers; real-time bidirectional communications in unidirectional technologies
(DVB), making use of a different technology return channel, covering aspects of
QoS
and
mobility;
IP-oriented
resource
management;
grids
in
mobile
environments; QoS support for WLANs and WMANs (IEEE 802.16); wireless sensor
networks; and privacy support using virtual identities and identity based mobility.
Research is also proceeding on the field of Future Internet. IMS signaling is
supported for session initialization. Resource Admission Control entities have two
169
main roles, i) admission control for new flows and ii) network elements
configuration (policy enforcement). Network policies for a particular sessions is, at
the moment, enforced in WIMAX and ADSL components. The admission control
process is feed with network measurements. In this way we developed a active
measurement platform for IP networks, addressing layer 3 and 4. To configure and
retrieve information from the entity, a web-based application was developed and
state of the art protocol was used to that interaction. In this same scope, the QoSaware version of two applications (telemedicine and e-learning) has been used to
demonstrate and validate the concept of application-driven end-to-end QoS.
Context-aware multiparty session - In future scenarios, context-aware services
and multicasting will together drive a new trend, since context-awareness can
exploit situations in which users share the same interests and request similar
services, increasing the effectiveness of session and network control. In these
environments, where groups may be created based on context, multicast takes a
new lead to the communications environment. However, context-aware networks
also introduce personalized concepts: any change to context, such as, location,
mobility, velocity, preferences, presence, can change the overall services and
network environments, requiring the network and multicast sessions to be
completely restructured in a very dynamic way. This dynamicity poses scalability
problems in current networks. We proposed an efficient architecture for contextaware multiparty session and network control which dynamically adapts to
contexts‘ and networks‘ dynamics and maintains the connectivity with the expected
requirements over session lifetime. We consider the concepts of dynamic session
and network control, driven by context, but introduce the concept of abstract trees
in the network to increase the stability of the network to any context change.
Mobile and ubiquitous computing – In the area of mobile and ubiquitous
computing we proposed an application developed for local and remote use, called
InHand, that is context-aware, presenting information related to the current user
context and provides location-aware support through the use of the Global
Positioning System (GPS).
170
Delay tolerant networks – In area of Delay Tolerant Networks (DTN) we
introduced a network architecture called Vehicular Wireless Burst Switching
(VWBS). The main objective of this architecture is to provide low-cost connectivity
solution for isolated and dispersed regions with no networks infrastructure. The
proposed architecture is based on the concept of Delay Tolerant Networks (DTN)
and can be applied to various scenarios, including rapid deployment of emergency
communication systems when all communication links have failed.
Security and Quantum Information
Byzantine attacks against network coding – Active attacks that inject
erroneous traffic in network coded information flows can have devastating effects
on the reliability of communication in large networks. A single corrupted packet can
jeopardize multiple flows. Our work, carried out with the team of Prof. Muriel
Medard at MIT, targeted the existing solutions and evaluated the overhead that is
associated with each of them. Whether or not to choose a particular strategy
depends very much on the size of the network and the rate at which attackers are
able to direct bogus traffic towards the end nodes.
Physical-layer security in stochastic wireless networks – Motivated by recent
developments in physical-layer security and stochastic geometry, we aim to
characterize the fundamental limits of secure communication in wireless networks.
Based on a general model in which legitimate nodes and potential eavesdroppers
are randomly scattered in space, we define the secure communication graph (sgraph) from the point of view of information-theoretic security. For the Poisson sgraph, we provide conclusive results for: (a) the in-degree and out-degree of a
node; (b) the isolation probability; and (c) the secrecy capacity between a node
and each of its neighbours. Our analysis reveals the innate connections between
information-theoretic
security
and
the
spatial
densities
of
legitimate
and
eavesdropper nodes. Joint work with the team of Prof. Moe Win at MIT.
Strong secrecy the physical layer- We continued our work our physical-layer
security based on information-theoretic principles bv publishing a comprehensive
journal paper with the fundamental security limits of wireless networks and a key
generation protocol that is optimal over a wide range of signal-to-noise ratios. We
171
further strengthened the secrecy condition for wireless physical layer security and
proved that there is no loss in secrecy rate from demanding that the total
equivocation rate of the eavesdropper converges to the entropy of the sent
messages asymptotically fast. Joint work with Matthieu Bloch, University of NotreDame.

of

attacks
by
an
eavesdropper with access to all the traffic in the network, we combined
cryptography with the basic properties of linear codes to yield a lightweight
cryptographic primitive. The key idea is to encrypt only the linear coefficients used
to mix different packets in network coding as an alternative to end-to-end
encryption. Our results show that we are able to reduce dramatically the required
number of encryption operations, while proving that the coded payload is
information-theoretically secure without the coefficients predicated on efficient
compression.
Secret key distribution with network coding – We extended our work on secret
key distribution protocols by considering cluster keys and key revocation. The
protocols capitalize on the broadcast property of the wireless medium and are
suitable for ad-hoc and sensor networks with node mobility. The next step will be to
combine them with trust management
schemes, possibly based on social
networking.
Physical-layer encryption with stream ciphers - Contemporary communication
systems are based on modular architectures, where the role of the physical layer is
essentially confined to error correction, whereas information security is typically
dealt with at the upper layers of the protocol stack. We consider a security
architecture that does exactly the opposite: information sequences are first
converted to longer channel code words which are then encrypted using a classical
stream cipher. Although this approach requires longer encryption sequences, our
analysis shows that the natural randomness of the noisy communication channel
can be used effectively against known-plaintext attacks. We also address practical
172
implementation issues in physical-layer encryption and discuss their impact on the
system architecture and on the security performance.
Impact of intensive attacks on the self-similarity degree of the network
traffic – It was developed a framework to inject network intensive attacks into
simulated traces of network traffic and to carry out their analyses using a fast
windowed version of the Variance Time (VT) estimator, optimized for the purpose of
estimating the self-similarity degree in a point-by-point manner. The estimator was
also applied to a trace of the well known MIT/DARPA data set, leading to the
conclusion that, during an attack, the insertion of a constant component may
induce a significant increase of the local scope self-similarity degree, which may be
used to suspect of the malicious activities and trigger further monitoring
mechanisms.
Security in 802.11 LANs – We continued our study for achieving fast, 802.1X-like
authentications during 802.11 handover reassociations. In this phase, we focused
mainly on the mobility management decisions, namely on knowing which APs are in
the neighborhood, on authenticating as fast as possible with them, and on the
decision to reassociate with other APs when beneficial for the station.
MIP mobility with security in 802.11 wireless networks - We studied the
merging of our previous work on fast 802.1X reauthentications with security on
Mobile IP (MIP) enabled networks. Nowadays, 802.11 networks rely on the 802.1X
authentication protocol for authenticating mobile nodes requiring network access.
MIP protocol can be used to enable those mobile nodes to access a network as their
home network, without any IP configurations. We studied ways to enable MIP
agents to get keys for message authentication purposes while (de)registering a
mobile node in a network and provide trustworthy information about MIP agents
that serve future roaming networks to mobile nodes. Furthermore, fast and secure
MIP handovers were gracefully handled with a slight change in the MIP protocol.
With our approach we achieved a functional, integrated security architecture
handling both link layer and network layer mobility.
Factorization of Blum integers - The security of many public key cryptosystems
is based on the hardness of factoring a Blum integer. This problem is reduced to
173
the problem of (numerically) integrating a certain meromorphic function. Two
algorithms were proposed, one based on the residue theorem and the other in the
(generalized) Cauchy‘s argument principle. In the former algorithm, computing the
residue of the function at a certain pole leads to obtain the factors of a Blum
integer. In the latter, a contour integral is considered, for which it is possible to
obtain an analytical solution with several branches. The computational difficulty
reduces to discover the branch of the solution that gives the precise integral. The
computational complexity of both algorithms is still open and needs to take into
account state-of-the-art integration methods.
Soundness and completeness of formal encryption- In their seminal work,
Abadi and Rogaway show that the formal (Dolev-Yao) notion of indistinguishability
is sound with respect to the computational model: pairs of messages that are
indistinguishable in the formal model become indistinguishable messages in the
computational model. However, this result has two weaknesses. First, it cannot
tolerate key-cycles. Second, it makes the too-strong assumption that the
underlying cryptography can hide all aspects of the plaintext, including its length.
Both of these weaknesses stem from a ‘gap‘ between the formal and computational
models, and we consider and close both weaknesses in this paper. It is shown that
the recently-introduced notion of KDM-security can provide soundness even in the
presence of keycycles, which is the ﬁrst time a gap has been closed by
strengthening the computational model. Encryption that reveals the length of
plaintexts is considered, and it is used to motivate a general examination about
information-leaking encryption. In particular, the conditions under which an
encryption scheme , which may leak some partial information, will provide
soundness and completeness to some (possibly weakened) version of the formal
model.
Improving authentication schemes with quantum information-
The
problem on how quantum resources can improve the security of authentication
protocols has been addressed. The starting point is the protocol introduced by
Brassard in 1983. In that protocol, the shared key is the seed of a pseudo-random
generator (PRG) and a hash function is used to create the authentication tag of a
public message. It was shown that a quantum encoding of secret bits offers more
174
security than the classical XOR function introduced by Brassard. Furthermore, we
proof that quantum resources can simultaneously improve both secrecy of the key
generated by the PRG as secrecy of the tag obtained with a hidden hash function.
Moreover, the proposed quantum protocol can be also used in order to authenticate
the quantum channel itself.
Farness constrains for the Dolev-Yao attacker- Fairness constraints for the
Dolev-Yao attacker, when checking liveness properties, were investigated. It was
showed that any fairness constraint that makes the standard Dolev-Yao attacker
sound w.r.t. an (honest) buffer, under the fair scheduling constraint, is a nonregular property.
Design of new security protocols - A fair contract signing protocol was propose
using quantum tamper-proof devices. In the proposed protocol the signing agents
do not need to communicate with a third trusted party during the signing phase,
which has been proved to be impossible using only classical information in
asynchronous networks. The protocol relies on decoherence of quantum information
to encode a global clock that works as a synchronization mechanism. The protocol
is can be implemented with existing quantum technology.
Traffic Engineering
Design and traffic engineering of MPLS and MPLS over WDM networks Network design is being addressed taking particular attention to both single layer
design (MPLS networks) and multi-layer design (MPLS over WDM networks). On the
MPLS over WDM network case, network design problems were addressed which are
a combined WDM lightpath routing, core LSR placement and LSP routing aiming to
determine
the
least
cost
network
solution.
In
particular,
a
cost
penalty
characterization for different degrees of survivability on the network was conducted
based on modelling techniques developed in previous years. A paper was published
on March of 2008 in the ―Networks and Spatial Economics‖ journal. The traffic
engineering problem was also addressed aiming to minimize the routing hop-count
while guaranteeing network survivability based on multiple disjoint paths. A paper
was published on 2008 in the form of a book Chapter with a selected set of papers
175
presented on the 2008 INFORMS Telecommunications Conference. These activities
have been done in collaboration with Prof. Luis Gouveia (Departamento de
Estatística e Investigação Operacional, Faculdade de Ciências, Universidade de
Lisboa).
Traffic engineering of Metro Ethernet networks - In this activity, we address
the problem of how to use the IEEE 802.1S Multiple Spanning Tree Protocol (MSTP)
to improve load balance, service disruption and survivability of Metro Ethernet
networks. We are pursuing two lines of research. In the first line of research, which
includes the pos-doc workplan of Dr. Dorabella Santos, we are defining optimization
models and developing suitable solving techniques able to obtain optimal solutions
for the traffic engineering problems. In particular, we have already published
different models and solution techniques, based on Dantzig-Wolfe decompositions,
to solve optimally different objective functions related to optimal network load
balance. This activity is being conducted in collaboration with Prof. Filipe Alvélos
(Departamento de Produção e Sistemas, Escola de Engenharia, Universidade do
Minho). Moreover, a collaboration with Prof. Michal Pioro (University of Warsaw,
Poland) has started in order to deal with the min-max optimization of link loads.
The aim is to use the polish previous work on max-min fairness to solve our
targeted optimization problems. In the second line of research, we are developing
of a traffic engineering server able to read and configure the switches in a remote
manner based on SNMP. This is a never ending activity where the aim of this server
is to set up a lab infrastructure where the optimization algorithms can be tested
and evaluated.
Optimization of VoD networks – A VoD network is typically composed by
multiple video servers. Whenever a movie is selected for provision, the front-end
system redirects the request to one of the video servers where it is available. Each
available movie is at one or more video servers, which has a maximum number of
stored movies (limited by its storage capacity) and a maximum number of movies
that can be provisioned (limited by its streaming capacity). There is a trade-off
between storage capacity and movie availability. Designing VoD networks is a
challenging task and factors like the average/peak usage of the system and the
titles popularity have to be considered for optimization. We have defined and
176
implemented an optimization tool for such networks that assumes a hierarchy
network of nodes, where the root node has the capacity to store all movies and the
remaining nodes are candidate nodes to have VoD servers installed. This work was
done under the dissertation of a Professional Master in Information Networking
(MSIN) between University of Aveiro and Carnegie Mellon University.
Detection of Internet applications - We have developed a software framework
for processing IP traffic flows, enabling the calculation of a set of relevant statistical
parameters and the identification of the underlying IP applications by using payload
analysis
techniques.
The
proposed
framework
was
able
to
achieve
good
identification results and was incorporated in DTMS-P2P monitoring platform as a
module that can be used at each probe for traffic engineering purposes. We have
developed a new approach, based on neural networks, that is able to identify flow
patterns generated by P2P Internet applications while overcoming the limitations of
existing
identification
approaches.
The
results
obtained
show
that,
when
conveniently trained, neural networks constitute a valuable tool to identify P2P
Internet applications since they are able to achieve good performance results while,
at the same time, avoid the most important disadvantages presented by the other
identification methods.
Detection and characterization of P2P Internet applications - Peer-to-peer
file-sharing systems have gained tremendous popularity in the past few years. The
traffic generated by P2P systems, and particularly BitTorrent, represents the major
portion of the global Internet traffic, largely overtaking the traffic share of the
World Wide Web. More users are continually joining such systems and more objects
are being made available, seducing even more users to join. An accurate mapping
of traffic to their applications can be very important for a broad range of network
management
and
measurement
tasks
including
traffic
engineering,
service
differentiation, performance/failure monitoring, and security. Traditional mapping
approaches have become increasingly inaccurate because many applications use
non-default or ephemeral port numbers, use well-known port numbers associated
with other applications, change application signatures or use traffic encryption. We
developed two new identification methodologies, one based on neural networks and
other based on principal component analysis. Both methodologies are able to
177
identify flow patterns generated by P2P Internet applications while overcoming the
limitations
of
existing
approaches.
The
results
obtained
show
that,
when
conveniently utilized, both methodologies constitute a valuable tool to identify P2P
Internet applications since they are able to achieve good performance results while,
at the same time, avoid the most important disadvantages presented by the other
identification methods. Nowadays, we see P2P systems evolving towards a Video on
Demand (VoD) platform. One of the main challenges of these systems is to
efficiently share data in the dynamic and continuously evolving Ad-Hoc networks of
users. This ability heavily depends on the peers' locations and characteristics on
this type of networks. Therefore, it is important to identify and characterize the
usage profiles of such P2P application. Towards that objective, we used the current
BitTorrent system to evaluate the peer-level characteristics of users sharing video
contents. These characteristics include geographical location, peers availability and
peers ―distance‖, measured in terms of the round trip time. From the results
obtained, we conclude that peers sharing video content present some unexpected
locality features that, if conveniently exploited, could greatly benefit VoD P2P
systems both in technological and service marketing terms.
Detection of network intrusions and anomalies - The detection of network
compromised hosts is currently performed at the network and host levels but any
one of these options presents important security flaws: at the host level, antivirus,
anti-spyware and personal firewalls are ineffective in the detection of hosts that are
compromised via new or target-specific malicious software while at the network
level network firewalls and Intrusion Detection Systems were developed to protect
the network from external attacks but they were not designed to detect and protect
against vulnerabilities that are already present inside the local area network. We
presented a new approach for the identification of illicit traffic that tries to
overcome
some
of
the
limitations
of
existing
approaches,
while
being
computationally efficient and easy to deploy. The approach is based on neural
networks and is able to detect illicit traffic based on the historical traffic profiles
presented by "licit" and "illicit" network applications. The evaluation of the proposed
methodology relies on traffic traces obtained in a controlled environment and
composed by licit traffic measured from normal activity of network applications and
malicious traffic synthetically generated using the SubSeven backdoor. The results
obtained show that the proposed methodology is able to achieve good identification
178
results, being at the same time computationally efficient and easy to implement in
real network scenarios.
Network modeling for performance prediction - Wired and wireless network
traffic exhibits peculiar and unpredictable behaviors that can be attributed to the
combination of different factors: the varying number of users, the capacity of the
network access links/points, network traffic matrices, users' mobility, background
traffic, diversity of applications, services and user behaviors. This scenario creates
an increasing need for tools that can cope with the continuous appearance of new
applications and QoS requirements and is able to aid in the global management
tasks of IP networks. We proposed an integrated management framework for
wireless and wired networks that utilizes the network models based on neural
networks previously developed and a new set of procedures allowing (i) to predict
network Quality of Service (QoS) evolution for varying number of users and user
characteristics and (ii) to assess the need for network upgrades. Additionally, the
research team have started the evolution of the network models based on neural
networks towards a integrated Markovian based model able to jointly characterize
users' behaviours and network characteristics and predict network performance in
future operational scenarios.
Congestion control in packet networks – Implementation and testing of
congestion control procedures for wireless links. In particular, we have been looking
at the specific aspects related to the performance of current TCP implementations
in wireless links. For example, one of the main problems present in wireless links
that affects the performance of TCP (and which is not present in e.g. high-speed
links) is the fact that TCP does not distinguish error losses from congestion losses.
Several solutions to this problem were proposed in the literature. Implementation
of end-to-end congestion control schemes for the Internet. In particular, testing of
alternative mechanisms for TCP sources envisaging high-speed networks with
significant
delays
(so-called
'high
bandwidth-delay
product'
links).

Optical burst switched networks - We studied and compared the four most
relevant simulators used in scientific and academic research to model OBS
networks
(Network

NCTUns,
and
OBSsimulator). Furthermore, we presented a study over the standard VoIP
protocols H.323, Session Initiation Protocol (SIP), Media Gateway Control Protocol
(MGCP), and H.248/Megaco.
Network Operations, Management and Planning
Towards the detection of encrypted P2P traffic - This research stream is
focused on the detection of P2P traffic using deep packet inspection methods or
behavioural-based methods. Regarding the use of packet inspection methods, we
are developing a methodology to detect encrypted traffic for most relevant file
sharing applications and for P2PTV, which is based on the creation of suitable rules
for snort. On the other hand, we have developed a new behavioural method based
on entropy for the detection of encrypted traffic on the dark. This new behaviouralbased method may also be used as a complement of the deep packet inspection
methods.
In-Network
management
-
Self-adaptation
in
the
scope
of
in-network
management is the capability of each node (and therefore of the network), to react
to changes insuring the proper network behavior, according to the defined
management policies. INM applications such as real-time monitoring and situationawareness provide state and context information to the decision processes within
the self-adaptation applications. The optimization includes the support of local
resources optimization (through predictive approach) and reconfiguration, accessnetwork selection and assisted routing (as optimal path selection). These functions
require the ability to discover the nodes, perform network bootstrap, and manage
entry/leave nodes. In this work we started the specification process of the selfadaptation mechanism to support in-network management, considering the
information that needs to be transferred between nodes and the decision process.
We are currently studying and applying game theory and Bayesian networks to
support this cooperation process.

Evaluation
is
usually
associated with connectivity related services, such as the provisioning of an internet
connection. Now operators are beginning to explore new business opportunities on
the All-over-IP world and beyond. New solutions are being deployed focusing on the
multimedia interactive contents. New network architectures will require extensions
to provide a clear vision on the service delivery quality, and new approaches on
cross-layer information will be envisioned. This work provides an insight on the
cross-layer overview of the current 3GPP networks, while featuring the analysis
until the end-to-end performance and end-user perception. It employs a correlation
between the most relevant parameters at each layer and underlines their
contribution to the upper layers. It further provides an analytical qualitative
analysis of the overall service performance by evaluating simulation results which
are sustained by both network and service performance metrics.
Network Applications and Services
Service orchestration in service oriented architectures – Developement of an
Open Platform for User-centric service Creation and Execution relying heavily on
SOA principles, an open service infrastructure was created that allows easy
creation, deployment and execution of new services by end-users. These services
consist of the composition of smaller execution units (called ‗base services‘) which
provide simple functionalities. The platform has several components to permit its
functionality in all spectrums of a service lifecycle, which communicate with each
other using SOAP. There is a portal for user-interaction, based on JBoss Portal and
using Portlet technology; this includes a powerful service editor that allows users to
compose their services and give them semantic meaning. All information, for both
services and users, is stored as XML descriptors on a repository based on a XDM
server. There is also a versatile matching and recommending module, implemented
as JSLEE Services, that allows the platform to automatically recommend services to
users based on their preferences. The Deployment Manager automatically controls
the various stages of the service lifecycle, from verifying if all resources necessary
to execute a service are present to deploying new instances of the base services in
order to balance load. The execution of a service, which essentially consists on the
orchestration of base services, is done by a SEE module, implemented in JSLEE.
181
This module uses SOAP to invoke each Base Service and receive its asynchronous
reply.
Service enablers for a multicast service oriented architecture – Development
of a Multicast Service Delivery Platform for group management and content
delivery. J2EE and IMS (3GPP IP Multimedia Subsystem) driven Telco and Web
convergence in Multicast Content Delivery was the most innovative resulting
software. Implementation of a J2EE-based Session Manager uses SIP servlets (JSR
#116) in order to set up and manage multicast content delivery; it enables more
complex web-like services to be easily created on top of it. Session Manager sets up
multicast sessions by behaving as a Back-to-Back SIP User Agent between the
media source and the Media Delivery Function (MDF), and between the MDF and
the terminals. The implementation was done using Enterprise Java Beans 3 and its
database abstraction layer JPA (Java Persistence API).

Detection
for
Lossy
Transmission Channels - We have proposed a new method to produce low
overhead redundant bits used to detect transmission errors of J2K streams on noisy
communication channels. This method takes advantage over already existing
algorithms on the JPEG 2000 standard and does not require any intrusive
alterations on the coder. We have shown that it is possible to improve standard
JPEG 2000 error resilience in exchange for null resource footprint. This capability
may be of particular importance for communication systems with small processing
capabilities such as wireless communications with mobile devices that have small
processing capabilities.
Distributed video coding - In 2008, the Image Group continued to have
distributed video coding as its main activity in the video coding area. Emphasis has
been put on Wyner-Ziv coding, a particular case of distributed video coding. The
main topics addressed were:
1. Adaptive deblocking filter for transform domain Wyner-Ziv video coding – Design
of an adaptive deblocking filter to improve both the subjective and objective video
182
qualities of a transform domain WZ video codec; the proposed filter is an
adaptation of the advanced deblocking filter defined in the H.264/AVC standard to a
WZ video codec.
2. Definition of efficient encoder rate control solutions for transform domain WynerZiv video coding – Design of encoder rate control mechanism which allow avoiding
a feedback channel to perform efficient rate control.
3. Refining side information for improved transform domain Wyner-Ziv video coding
– Design of a novel side information refinement (SIR) algorithm for a transform
domain WZ video codec based on a learning approach where the side information is
successively improved as the decoding proceeds.
4. Statistical motion learning for improved transform domain Wyner-Ziv video
coding – Design of a novel motion learning approach to successively improve the
rate-distortion performance of the WZ video codec as the decoding proceeds,
making use of the already decoded transform bands to improve the decoding
process for the remaining transform bands.
5. Flexible side information generation framework for distributed video coding –
Design of a flexible framework to generate side information (SI) at the block level
using two modes: while the first mode corresponds to a motion compensated
interpolation
(MCI)
technique, the second
mode corresponds to a
motion
compensated quality enhancement (MCQE) technique where a low quality Intra
block sent by the encoder is used to generate the SI by doing motion estimation
with the help of the reference frames.
6. Distributed video coding with multiple side information – Targets the exploitation
of multiple side informations generated by frame interpolation and frame
extrapolation.
7. Dynamic quality control for transform domain Wyner-Ziv video coding – Design
of an efficient quality control algorithm to maintain a uniform quality along time in
low encoding complexity WZ video coding by dynamically adapting the quantization
parameters depending on the desired target quality without any a priori knowledge
about the sequence characteristics
8. Low complexity intra mode selection for efficient distributed video coding –
Design of a low complexity Intra mode selection algorithm to define the most
critical blocks in the WZ frame and help the decoder with some reliable data for
183
those blocks. For each block, the novel coding mode selection algorithm estimates
the encoding rate for the Intra based and WZ coding modes and determines the
best coding mode while maintaining a low encoder complexity
Following these contributions which were published at major conferences and
journals, the Image Group maintained its top rank place within research groups
working on distributed video coding.
Rate control – In 2007, we have continued to address the problem of rate control
both for object-based and frame-based coding architectures. In 2007, the main
issues addressed were: 1. Definition of a rate control architecture for joint objectbased MPEG-4 video encoding; 2. Joint bit-allocation strategies for multi-sequence
H.264/AVC video coding rate control; 3. Improved feedback compensation
mechanisms for multiple video object encoding rate control.
Generic audiovisual content automatic summarization – In this topic, we
have proposed and evaluates a fully automatic summarization application for
generic audiovisual based on MPEG-7 compliant hierarchical summary descriptions,
which allows providing flexibility, low complexity, and interoperability. The novelty
of the solution regarded the exploitation of a three features, low-level arousal
model to generate the summary metadata needed to instantiate MPEG-7 compliant
summary descriptions with all the advantages this brings. Moreover, a novel, solid
evaluation study has been performed.
Quality evaluation - We continued the work started two years ago; during 2008,
research as been focused on no-reference, objective metrics for quality evaluation
of video sequences, subject to lossy encoding (MPEG-2 and H.264/AVC). Quality
evaluation considering also transmission errors (packet losses) has been initiated. A
new metric for the PSNR estimation of H.264/AVC encoded sequences has been
developed and presented at EUSIPCO 2008; preliminary work on the derivation of
perceptual metrics for video has been conducted and first results submitted to
ConfTele 2009.
184
Object-based video coding - In 2007 the research activity in this topic lead to
the proposal of an improved rate control architecture for jointly encoding multiple
video objects in compliance with various MPEG-4 Visual video profiles. Still in this
area, innovative contributions have been made on new buffer and video object
distortion feedback compensation mechanisms for efficiently dealing with deviations
between the ideal and the actual behavior of video scene encoders when jointly
encoding multiple arbitrarily shaped video objects in the context of compliant lowdelay object-based MPEG-4 video coding. The proposed solution outperforms the
non-normative MPEG-4 reference rate control algorithm for a wide range of bit
rates and spatio-temporal resolutions, for typical test sequences. Additionally, in
2007, the problem of jointly encoding multiple video sequences (MVSs) with the
H.264/AVC video coding standard has been addressed. Jointly controlling the
encoding of multiple video sequences (VSs) allows the dynamical allocation of the
overall available resources (e.g., bit rate and buffer space) along time and between
the various VSs to encode; this brings a better rate-distortion (RD) trade-off,
notably, when compared with single VS encoding with a rigid allocation of
resources. The major achievement of this activity has been a new method for joint
bit allocating taking into the account the frame coding complexity and the coding
type weight of each frame to be encoded for each joint encoding time instant that is
able to achieve higher average picture quality and lower quality variations along
time and between the various video sequences, when compared with independent
sequence encoding derived from JM reference model rate control solution for
H.264/AVC. Finally, by the end of 2007, a new research activity has been initiated
addressing the problem of how to efficiently combine error resilience and ratecontrol techniques for frame-based video coding systems. Results for this activity
will be available in 2008.
Video error resilience - In 2008, research on how to efficiently combine error
resilience and rate-control techniques for frame-based video coding systems, such
as those based on the H.264/AVC video coding standard, was carried out. The
major achievement was the proposal of a method that efficiently and automatically
takes into account the packet loss rate of the network used for video transmission
when performing coding mode decisions at the encoder. This method can be used
to efficiently generate error resilient H.264/AVC bitstreams that are perfectly
adapted to the channel error characteristics.
185
Image and video processing and analysis – On this research area, our work
has focused on the following directions: (1) video analysis of underwater images, in
cooperation with INRB/IPIMAR, to quantify the abundance of Norway lobsters and
their burrows in the Portuguese Atlantic and Mediterranean coasts; (2) video
analysis of road pavement images for supervision and management support of road
infrastructures; (3) people recognition using using palmprint biometrics; (4)
development of image segmentation quality evaluation metrics; (5) automatic
detection of cars and recognition of their make and model, in video captured at a
parking garage entrance.

The
research
activity
in
computer
graphics
was
concentrated on data structures for geometric models. The work carried out was
focused on simplification algorithms for polygonal meshes and in compression,
transmission, and progressive visualization of 3D geometric models.
Some work
was also initiated in graphics for mobile devices, in particular 3D games for these
devices.
Secure Biometrics – We started a research front in the topic of secure
biometrics.In
particular, the use of distributed source coding concepts and hash
functions to secure biometric data was investigated. This new approach makes it
possible to generate many different templates from the same biometric data,
which
can
be
canceled
if
they
are
compromised.
Furthermore,
it
also
guarantees that the original biometric data cannot be recovered from the
stored data, thus guaranteeing its privacy.
Blind Image Deblurring - The blind image deblurring method that had been
developed in 2007 has been greatly improved during 2008 and extended, in two
main directions: (1) It now is able to process color, multispectral and multi-frame
images; (2) it now can deblur images in which different parts are subject to
different blurs, such as images in which a foreground object has motion blur and
the background has defocus blur. The development of this extension will, very
probably, proceed in the next year, because there is still room for further
improvement.
A patent on this blind deblurring method has been applied for.
186
Pattern Recognition and Automatic Learning
Dissimilarity measures for symbolic sequences – In this research front, we
have continued our work on the development of information-theoretic techniques to
measure dissimilarity between symbolic sequences (e.g., text). Informationtheoretic dissimilarity measures are ―agnostic‖ in the sense that they do not
assume any specific generative model, nor do they require estimation of such
models. During 2008, we have continued to concentrated on non-extensive
information theoretic kernels, but now on practical applications, namely for text
classification. This work resulted in a paper at the International Conference on
Machine Learning (ICML‘08, the top machine learning conference) and a journal
paper submitted (and accepted with minor revisions) to the Journal of Machine
Learning Research (the top machine learning journal).
Compression Based Classification – In 2008 we worked on text classification
methods based on lossless compression algorithms of the Lempel-Ziv family. Most
approaches to text classification rely on some measure of (dis)similarity between
sequences of symbols. Information theoretic measures have the advantage of
making very few assumptions on the models which are considered to have
generated the sequences, and have been the focus of recent interest. In this line of
work we have used the Ziv-Merhav method and the Cai-Kulkarni-Verdú methods for
the estimation of relative entropy from sequences of symbols, with excellent results
in authorship attribution tasks.
Clustering – Exploiting the notion of Evidence Accumulation Clustering (EAC), and
a resampling-based cluster stability measure, we have continued to work on the
problem of learning similarities from data. The developed similarity learning method
was shown to have state-of-the-art discriminatory capacity and to better revela the
intrinsic cluster structure of the data. We also explored combination techniques
based on the EAC paradigm, but with different weighting of the clusterings using
quality measures. Fusion techniques from supervised and unsupervised learning
(classifier fusion and cluster ensemble methods) were exploited simultaneously in
the problem of features selection, yielding new promising techniques.
187
Speech Analysis - A discriminative training method applied to a hybrid neuralnetwork/hidden-Markov-model phoneme recognition system was proposed. Also, a
fast discriminative training algorithm for speech recognition, based on hidden
Markov models was implemented and will be proposed for publication soon. A
robust spoken commands recognizer was developed in the scope of the Tecnovoz
project. It incorporates an efficient noise-robust front-end, triphone models and

Tecnovoz
is
a
national
collaborative
project
involving
4
scientific
organizations that work on speech recognition and speech synthesis and 8
industrial organizations that want to introduce speech technology in their
products. This project represents an opportunity for Portugal to play a
major role in this technology and to have a word in the development of
speech applications using its own language. The project started in July,
2006 and, in the end, 14 different applications and services are expected to
use speech as an alternative to other input/output interfaces.
The work carried out by IT researchers is related to noise robustness in
automatic speech recognition. IT is developing a module for the detection
of connected commands with speaker independence and capable of
working in adverse environments. The recognizer will be embedded in 2
demonstrators that will be built by 2 industrial project participating
partners. One of these demonstrators will be used inside an automobile
and the other in the proximity of noisy machinery. Both environments
represent a technical challenge for the recognition engine that IT is
developing.
189
In the first semester of the project, we built a recognizer trained with an
available Portuguese database of digits recorded through the telephone
network. Another participant of the project will collect a command
database whose contents will be used in the training of the final models.

Advanced MBMS for the future mobile world
Funding
EU,IST Programme
Descript.
The strategic objective of C-MOBILE is to foster the evolution of the
mobile broadcast business by providing enhancements to the 3GPP
MBMS for systems beyond 3G. It will address both resource efficiency
and service flexibility, by close coupling of broadcast and communication
capabilities on all layers, covering the radio access, core network and
the service enablers, across multiple technologies, providing a smooth
migration for MBMS evolution, which will be in line with the vision of a
federated global multicast broadcast transport as well as emerging
beyond 3G standards. Within the radio access network it will propose
new radio interface technologies, radio resource management and new
topological approaches in the architecture for an efficient support of
enhanced
MBMS
services
allowing
a
commercially
attractive
implementation. C-MOBILE will help to understand how best to organise
and schedule MBMS content from the BM-SC through the core network,
radio access, to the end users. Since this is multimedia content,
interactions with the 3GPP IP Multimedia Subsystem are expected and
C-MOBILE will explicitly investigate how best MBMS can make use of
capabilities provided by the IMS. The current concept of group
192
communication is narrow within Release 6 MBMS specification. CMOBILE will research, investigate and define ways to use multicast
technology to support personalized services and in particular the
concept of multicast content community where users also contribute to
the multicast service. Key market and business requirements for
multicast-broadcast services will be identified to aid defining research
directions, leading also to new business models involving the various
players. To that end it is critical to understand the needs of multicastbroadcast users, network operators, and content providers. The project
intends to make important contributions to the standardisation bodies
and to prove experimentally or via system level simulations innovative
concepts.

Title
An All-Wireless Mobile Network Architecture
Funding
EU,IST Programme
Descript.
We propose to study how to build an all-wireless Internet that could
grow and gradually replace the existing Internet. In our vision, the
access points of unlicensed cellular networks cooperate to create a
wireless communication infrastructure. Such a wireless network must be
self-organizing to maximize the network capacity and capabilities.
Ultimately, the all-wireless interconnection of cooperating access points
will only require limited connectivity to the wired infrastructure. We call
this all-wireless infrastructure the Radio Internet. The goal of the project
is to study how to make the Radio Internet become a reality with an
Internet-like growth towards a scalable and robust communication
infrastructure.
The objective of the project is to design, implement, and experimentally
validate an all-wireless interconnection architecture based on advanced
wireless
transmission
standards,
multiple
techniques
radio,
and
(i.e.,
new
multiple
MAC,

193
mobility. We will develop a suitable measurement methodology and set
up experimental prototypes to validate our concepts. Testbeds will be
used or deployed for proof-of-concept and validation of the proposed
architecture and communication mechanisms.
To achieve the vision of the Radio Internet, we need to adopt a
disruptive approach with respect to the current Internet: rethink the
overall architecture with wireless networks as the central technology and
propose a new interconnection architecture founded on the principle of
all-wireless networks with some isolated wired long-haul links. By
defining
new

designing self-configuring and self healing mechanisms, a large number

This project will address new, statistically based methods for image
restoration and reconstruction. The fundamental approach consists of using
representations of natural images yielding sparse and near-independent
coefficients. This goal will be pursued along two main lines:
1. Methods relying on a fixed, wavelet-based representation. The project
shall extend existing methods of denoising, and of deblurring using a
known blur operator, to the blind deblurring / denoising situation. The main
approach will consist of taking the blur operator as an additional unknown
in a Bayesian formulation of the problem.

Space-Time-Types: Behavioural and Spatial Type Systems
Funding
FCT/POSC
Descript.
Our goal is the development of static analysis systems to verify safety
and liveness properties of concurrent distributed systems specified in
196
calculi of mobile processes. The properties we are interested in are not
only behavioural, like deadlock freedom or conformance to a protocol,
but also structural (or spatial), like connectivity or resource usage. The
existing systems treat only some of the behavioural properties, in a
limited way (not purely static, or in very restricted settings). Building on
existing work on behavioural types and on spatial logics, we aim at the
development of richer notions of types, able of expressing behavioural
and spatial properties of distributed systems. We envisage expressive,
yet decidable and computationally tractable static analysis systems,
which allow to formally prove that a process enjoys a certain property,
and that there will be no run-time property violations.

Sensor Information Gathering with Patrol Nodes
Funding
FCT/POSC
Descript.
The main goals of the SIGAPANO (Sensor Information GAthering with
PAtrol NOdes) research project are to contribute to a fundamental
understanding of wireless sensor networks with mobile patrol nodes,
provide
an
appropriate
middleware
design
for
this
class
of
communication networks and develop a state-of-the-art sensor network
prototype to demonstrate their applicability for tasks as critical as forest
monitoring and fire detection. Wireless sensor networks made of tiny,
low-cost
devices
capable
of
sensing
the
physical
world
and
communicating over radio links, are significantly different from classical
wireless networks like GSM or wireless LANs: (a) the design of a sensor
network is strongly driven by its particular application, (b) sensor nodes
are
highly
constrained
in
terms
of
power
consumption
and
computational complexity, and (c) since the network is dense and the
nodes share a common objective - to gather and convey information cooperation can be used to enhance the network´s efficiency. Previous
work on the communications aspects of wireless sensor networks has
197
focused on mostly static models, in which the sensor nodes keep their
positions, and transmit the picked-up data to a central base station in a
fixed location. Under this scenario, the sensor nodes are expected to
store and process the data, coordinate their transmissions, organize the
routing of messages within the network and relay the data to a remote
receiver - a challenging set of tasks which might prove impractical given
the power constraints on the sensor nodes and the expected size of the
network. We propose to investigate an alternative approach, based on a
limited set of mobile ad-hoc nodes with increased processing and
communication capabilities, which are placed e.g. on a robot, a jeep or a
helicopter and are thus able to move as a patrol around the wireless
sensor network and, thus, relieve the sensor nodes from powerconsuming networking tasks by collecting the required data in loco with
less and more reliable transmissions. The project will be divided in three
complementary parts:
(1) Fundamental performance limits of sensor networks with patrol
nodes (DCCFC, Porto): we will define adequate models for this class
of wireless network and investigate the impact of the patrol nodes‘
mobility on the connectivity, the capacity and the average lifetime
of the network using elements of information theory, graph theory
and stochastic processes. (2) Network architecture and middleware
for sensor networks with patrol Nodes (CRI, Lisbon): is to study and
propose a protocol stack that provides an interface between the
sensor networks and adhoc patrol nodes based on the theoretical
results of part 1. (3) Development of a prototype sensor network
for forest monitoring and fire detection. (DCC-FC + CRI):
(2) we will use two wireless sensor network kits to implement the
sensor
network architecture investigated
in part
1
and
the
middleware package developed in part 2, and conclude with lab
demonstrations and field tests in Portuguese forests.

FCT/PTDC
Descript.
The project has the main objective of developing a set of experimental
tools for the study of the risk of fracture in elderly people. The risk of
fracture is related to the risk of fall and to bone resistance. The aim of
this study is to develop a risk profile that can be used to identify
community-residing elderly at high risk of falling and to establish
strategies to prevent falls in healthy older adults and to identify the
variables associated with an increased risk of falls and fractures. The
use of advance clustering techniques for data reduction should allow the
identification of the relevant variables for kinematics and kinetics
parameters that are fundamental for the maintenance and development
of the balance and locomotion skills of daily live in elderly population
and also to identify high-risk groups for falls and fractures. The results
of the questionnaire assessment, field tests and laboratory studies
should allow the establishment of guidelines for the development of
exercise and perceptive training programs.

The KLog project envisages to investigate and apply the tools and
techniques of mathematical logic, in a broad sense, to the systematic
study and design of special purpose classical and quantum kleistic (from
the greek word kleisis) logics, that may provide a deeper understanding
of the various aspects of information security, and ultimately contribute
to the improvement of the available toolset of formal methods. This
research will contribute to a better understanding of the relevant
concepts and their relationships, and help to solve and clarify some of
the open problems and key concerns of the area. The subjects to be
addressed include the design and study of logics for reasoning about
classical security protocols in distributed settings, ranging from the ideal
world of perfect cryptography to the more realistic probabilistic setting
where polynomially bounded adversaries are assumed, while also
exploring type-theoretical logic systems targeted at flexible information
flow analysis in languages supporting code mobility and declassification
that could be used to express distributed protocols; and the logical
study of quantum computation and information and its applications to
security, eventually leading to quantum extensions of the logics for
classical security, by considering quantum computation capabilities and
quantum communication channels. The project will also not neglect the
development of the logical foundations of combined logics and their
algebraic
counterparts
motivated
by
the

Accordingly, the project is organized in three tasks: (T0) Logic in

MOGGY - A Browser-Based Massive Multiplayer Online Game Engine
Architecture
Funding
Descript.
FCT/PTDC
A game engine is a structured collection of several software modules (i.e.
2D
and
3D
graphics,
physics,
collision
detection,
input/output,
sound, artificial intelligence, network, database, and graphical user
interface modules) that together enable to run video games on a
computer, game console, PDA, etc.
The essential difference between a traditional game engine and a MMOG
(Multiplayer Online Game) engine lies in the network and database
modules. Usually, MMOGs have large databases over a distributed
network of servers sometimes handling a huge number of logged-on
users.
Distributed,
real-time
MMOGs
are
a
real
challenge
for
current
networking technologies in terms of quality of service (depending on
networking resources such as bandwidth, latency, and computational
power), network architectures and topologies (peer-to-peer, client/server,
server-network), data and control architectures (centralized, distributed,
replicated), scalability (i.e. adaptation to the resource changes as a result
of the increase of players), and security (fighting back against cheaters
and vandals).
It is true that here is not much we can do about networking resources.
However, by choosing a suited architecture for networking, data, and
control, we can rid MMOGs of some resource limitations, or use
compensatory
techniques to
relax
their
requirements.
The
main
requirements for a MMOG engine are the following:
scalabilty, fault tolerance and persistence, computational efficiency, and
security.
This project aims to research solutions to fulfill these requirements, as
well as friendly game rules learning mechanisms, that at present tend to
201
limit the development of more powerful and user friendly BBMMOGs.
For that, we propose to use on-demand grid technology as the underlying
infrastructure for hosting online games. Although it has been geared
initially towards First Person Shooter (FPS) games (the worst case in
terms of processing), several of the gaming services are applicable to
MMORPG (Massively Multiplayer Online Role Palying Games) and BBMMOG
games as well.
FPS games require a tremendous amount of server resources, and, due
to interactivity requirements, they also require that the server resources
be placed close to the players. Since concentration of player populations
can vary dramatically over time, intelligent on-demand allocation of
computing resources is critical to optimize server utilization while
maximizing game playing satisfaction. In addition, a grid-based shared
infrastructure provides economies of scale and industrial scale resiliency,
necessary prerequisites for a successful online gaming industry.

Beyond features: similarity-based pattern analysis and recognition
Funding
EU-FP7 ICT
Descript.
The challenge of automatic pattern analysis and recognition (or machine
learning) is to develop computational methods which learn to distinguish
among a number of classes from examples, with a view to endow
artificial systems with the ability to improve their own performance in
the light of new external stimuli. This ability is instrumental in building
next-generation artificial cognitive systems which, as opposed to
traditional machine or computer systems, can be characterized as
systems which cope with novel or indeterminate situations, which aim to
achieve general goals as opposed to solving specific problems, and
which integrate capabilities normally associated with people or animals.
The
socio-economic
implications
of
this
scientific
endeavor
are
enormous, as it will have applications in a wide variety of real-world
scenarios ranging from industrial manufacturing to vehicle control and
traffic safety, to remote and on-site (environmental) sensing and
monitoring, and to medical diagnostics and therapeutics. This project
aims at bringing to full maturation a paradigm shift that is currently just
emerging within the pattern recognition domain, where researchers are
becoming increasingly aware of the importance of similarity information
per se, as opposed to the classical feature-based approach. Indeed, the
notion of similarity has long been recognized to lie at the very heart of
204
human cognitive processes and can be considered as a connection
between perception and higher-level knowledge, a crucial factor in the
process of human recognition and categorization. We shall undertake a
thorough study of several aspects of purely similarity-based pattern
recognition
methods,
from
the
theoretical,
computational,
and
applicative perspective. We aim at covering a wide range of problems
and
perspectives,
considering
both
supervised
and
unsupervised
learning paradigms, generative and discriminative models, and our
interest will range from purely theoretical problems to real-world
practical applications. We shall apply our algorithms to challenging
biomedical problems that lend themselves particularly well to similaritybased approaches, namely, to the analysis of tissue micro-array images
of renal cell carcinoma and to magnetic resonance brain imaging for the
diagnosis of mental illness.

Calculi and Languages for Sensor Networks
Funding
FCT/PTDC
Descript.
The main goals of the CALLAS (Calculi and Languages for Sensor
Networks) research project are: to contribute towards a fundamental
understanding of wireless sensor networks by developing formal tools
based
on
process
calculi;
to
provide
adequate
programming
architectures
for dynamically configurable sensor nodes; and to validate the proposed
designs in real-life prototype sensor applications.
Wireless sensor networks, made of tiny, low-cost devices capable of
sensing the physical world and communicating over radio links, are
significantly different from classical wireless networks such as GSM or
wireless LANs: (a) the design of a sensor network is strongly driven by
its particular application, (b) sensor nodes are highly constrained in
terms of power consumption and computational resources (CPU,
memory),
and
(c)
large-scale
sensor
applications
require
205
self-
configuration
and
distributed
software
updates
without
human
intervention.
Previous work on fundamental aspects of wireless sensor networks has
mostly focused on communication-oriented models, in which the sensor
nodes are assumed to store and process the data, coordinate their
transmissions, organize the routing of messages within the network, and
relay the data to a remote receiver. Although some of these models
provide useful insights (e.g. into the connectivity characteristics or the
overall power efficiency of sensor networks) there is a strong need for
formal methods that capture the inherent processing and memory
constraints, and
illuminate the massively parallel nature of in-network computation.
Our take is to develop process calculi for sensor networks building on
formalisms for concurrent distributed systems and mobile code (most
notably, pi-calculus). The envisioned tools will enable us to (a) prove the
correctness
and
feasibility
of
different
data
gathering
and
communication
protocols (e.g. by exploiting behavioral equivalence between processes),
and
(b) carry
out
formal
comparisons
of
different
schemes by
quantifying
the minimum amount of required resources.
Based on the results of the first task we will attack another fundamental
problem in sensor networks: the need
for sensor programming
languages
with self-configuration and distributed update capabilities. We propose
to develop specifically tailored high level idioms for sensor networks that
capitalize on notions such as mobile code and self-maintenance.
Finally, we will implement and test the developed programming tools on
a sensor networking prototype. Real-life experiments will allow us to
better understand sensor networking constraints and further improve
our designs. We believe that our interdisciplinary team of computer
scientists and electrical engineers is well equipped to contribute both in
206
theory
and
in
practice
to
the
advancement
of
sensor

Context Casting
Funding
EU-FP7 ICT
Descript.
Project Context Casting (C-CAST) main objective is to evolve mobile
multimedia multicasting to exploit the increasing integration of mobile
devices with our everyday physical world and environment. The key
motivation for this project and why we believe Europe needs a project
on Context Casting is because multicasting is the key enabler that will
make mobile context aware services commercially attractive. Use of
mobile multicast communication especially for multimedia content has
always been a very attractive proposition. There will be many situations
when a multicast or broadcast will be a much more affective and
appropriate form of communication service but the majority are
dynamic, situation specific and consequently great service opportunities
are lost. C-CAST is based on two main competence areas: creation of
context awareness and multicasting technologies. Context information
defines groups that demand the same information or service. These
services are delivered efficiently by multicasting bearers. The project will
research, investigate and define ways to use the situation/environment
of a user (a mobile device) to initiate group communication. This
environment mediated multicast may be triggered by an event or
something in the physical environment offering a situation or context
orientated service. C-CAST will provide an end-to-end context-aware
communication framework specifically for intelligent multicast-broadcast
services.

FIbre-WIreless Access: Future Integrated Access Architecture Based on
Optical and Broadband Wireless Technologies
Funding
208
Descript.
The main objective of the project is to build an access and metropolitan
network architecture that integrates upcoming optical and broadband
wireless
technologies,
thereby
enjoying
the
complementary
characteristics of these technologies, so that the user will be able to
access diverse communication services in a transparent manner and with
a high degree of ubiquity, being able to move among different networks,
while maintaining a high resource utilization efficiency. Key issues in this
context are future end user needs, integrated QoS support and
optimized
service
provisioning.
The
project
will
unveil
research
opportunities, issue recommendations and propose novel mechanisms
associated with the convergence within this heterogeneous access
scenario and will thus serve as a basis for long-term research projects in
this direction.

Title
Network Coding for Robust Architectures in Volatile Environments
Funding
EU-FP7 ICT
Descript.
N-CRAVE will deliver a proof-of-concept for network coding as the major
enabler in
dynamic wireless network
environments with
multiple
communicating peers, where robustness is a key challenge. The simple,
yet disruptive idea of network coding is that nodes are allowed to not
only forward but also process and mix the incoming independent
information flows. The objective is to develop solutions for architecting
and
controlling
wireless
networks
in
performance-challenged
and
resource-constrained environments.
N-CRAVE will advance knowledge of fundamentals of network coding for
210
improving attainable performance limits of networked systems for
capacity, throughput, latency, complexity and energy with a view
towards practically encountered scenarios. Key protocol components of
the access, transport and network layers that operate hand-in-hand with
network coding will be developed. In doing so, novel lightweight
techniques will be designed based on convex optimization, linear algebra
and backpressure control principles for transporting maximal amount of
data over the network. Emphasis will be placed on advanced modes of
information
transport
such
as
multi-cast
and
group-to-group
communication with multiple simultaneous sessions in highly volatile
environments.
Innovative content distribution and storage methods will be developed
for various wireless architectures and application-driven performance
metrics, such as throughput, delay and fairness. A major goal will be to
make
the
techniques
viable
in
dynamically
changing,
volatile
environments by preserving low computational complexity and signalling
load.
Besides inherent benefits of network coding in capacity provisioning and
robustness, positive ramifications in security will be used to fortify
confidentiality, secrecy and resilience to data corruption and other
threats. Finally the project will deliver an experimental wireless test-bed
on which various network coding techniques will be implemented and
validated.

Net-PEEC
Network Coding Protocols for Peer-to-Peer Content Distribution
DoCoMo
The most striking difference between network coded peer to peer
networks and its classical non coded counterpart, is that operations
carried out by the nodes are not limited to storing and forwarding copies
of requested fragments. In fact, they are allowed to combine different
fragments using linear combinations, thus mixing and spreading the data
211
among multiple packets. By means of this coding and dissemination
approach, we enhance the degree of diversity in the network and thus
increase the likelihood that packets received from different sources carry
useful data that can be decoded for timely play out.
The main goal of this project is thus to exploit the rich body of network
coding theory towards developing highly efficient and robust protocols
for content distribution in peer to peer networks. The expected outcomes
of this research are (a) an in depth understanding of the applicability of
network coding to distributed storage and dissemination with particular
focus on the requirements imposed by streaming media, (b) a set of
protocols that can be readily used for this task, (c) performance
evaluation both analytically and by means of computer simulation.

FCT/PTDC
The main goal of the project is to address and tackle some of the most
challenging open problems in the area of quantum security. Significant
original results are expected in several fronts, such as: design and
analysis of quantum protocols, model checking of quantum systems,
quantum cryptoanalysis of classical protocols, quantum solutions to
classical impossibilities. Several applications will be investigated with the
purpose of understating how they can be speed up using quantum
information. The focus will be on cryptographic tasks, such as zero
knowledge proof systems, e-voting, authentication and contract signing.
A model-checking tool for quantum systems will be produced within the
project, as well as a simulator for testing quantum attacks on symmetric
cryptosystems.

Robust joint source/channel coding for multimedia communications
GRICES-CNRS
213
Descript.
The MDC makes it possible to control easily the amount of redundancy
introduced in the transmitted signal while maintaining good quality
decoding whatever the state of the channel. However, in the case of non
stationary noisy channel, few works have been dedicated to the tuning
of the redundancy according to the noise level. The goal of this project is
to design a MDC that controls automatically this redundancy between
the descriptors according to the channel state. Furthermore, in case of
embedded devices we also propose to introduce distributed coding to
move the complexity from the coder to the decoder. The proposed
framework includes a wavelet transform and an optimal bit allocation
process of the binary resource across the different descriptors and the
different wavelet subbands. Our model will take into account both the
knowledge
of
the
channels
characteristics
(heterogeneity,
non
stationarity, ...) and the propagation conditions encountered in a real
environment.

SCODE
SCODE- Scanned COmpound Document Encoder
FCT/PTDC
The main objective of this work is to investigate and develop an usable
version of a MMP based scanned documents encoder, that is able to
improve on the encoding performance of current state-of-the-art
compound image encoders, like DjVu. In order to achieve this, some
important tasks must be achieved:
- investigate and develop efficient methods for layer-based or blockbased image segmentation, for optimisation of the overall
MMP-based encoder´s performance;
- optimise the dictionary adaptation process in order to increase the
coding performance of MMP for the images corresponding to the
segmented layers or block types;
- efficiently implement a computational version of the method and
214
investigate relevant functional optimizations, in order to reduce the
computational complexity of the algorithm without compromising its
coding efficiency;
- perform a set of experimental tests in order to compare the encoding
performance of the new method with the one of other
state-of-the-art methods.

Title
Secure Widespread Identities for Federated Telecommunications
Funding
EU-FP7 ICT
Descript.
SWIFT will develop a standards aligned model for user data linked to
identities or personae with the user in control of the information
exchanged. It will separate management from resolution of identities at
all layers, i.e. from the service to link, considering both privacy and
―need-to-know‖ concerns.
SWIFT‘s user-centric Id approach addresses three views: 1) users have
complete control over privacy and disclosed information dependent on
the service accessed; 2) services can use a generic treatment of
authentication, authorization, access control independent of the layer
services managed by a unique identity; 3) commercial players can
215
leverage new business solutions for operator, service provider or 3rd
parties through its federation approach.
As a STREP, SWIFT aims to primarily impact technology research and
related standardization in the manufacturing and telecom operator
domains. The consortium is balanced accordingly. The social and legal
domain will be addressed by liaisons and cooperations.

264
Integrated Circuits and Systems
Scope and Objectives:
The IC Design Automation group addresses the development of design automation
tools for ―System-on-Chip‖ applications, the design of state-of-the-art Analog and
Mixed-Signal
IC
prototypes
and
the
development
of
E-Design/E-Learning
environments to support design activities.
IC Design Automation:
The group research activities on the design automation domain include: (1) circuit
and
system
optimization
techniques,
particularly,
the
use
of
evolutionary
computation techniques to optimize a broad range of circuits and systems; (2)
automatic circuit and systems topology search based on evolutionary computation
methodologies; (3) symbolic analysis and synthesis for analog and mixed signal
systems. The development of E-Design/E-Learning environments to support
collaborative design activities include the research on areas such as web/data
mining techniques, as well as partnerships with distance learning research teams.
IC Design:
The group research activities on the IC design include:
1) design of analog and mixed signal ICs for telecom, e.g., the analog structures for
4G mobile terminals;
2) research on embedded system applied to enhance the reconfigurability of analog
and mixed signal systems;
3) design and research on the implementation of circuits and systems on organic
technologies.
Radioastronomy
The activity of this group consists of the development of instrumentation for
measurement and characterization of low-level radiation from outer space, in the
microwave region. Instrumentation refers both to the electronics and physical
infrastructure, including antenna mounts, drives and ancillary equipment, such as
data acquisition for environmental and meteorological variables.
265
Main activities in 2008 were:
GEM project:
The Cassegrain 9-meter dish from Vertex/General Dynamics offered by Portugal
Telecom was successfully installed.
The IF of the 5GHz receiver, a double arm feeding a polarimeter correlator with
circular polarization components was designed, tested and assembled. It is a new
type of state-of-the art radioastronomy polarimeters, with a cryogenic frontend,
using LNAs based on ultra-low noise InP HEMTs, characteristics designed at IT,
manufactured by Chalmers University of Technology, after license from JPL/NASA.
A new optics configuration for the antenna, comprising a new corrugated horn feed,
modelled with GRASP (ESA certified) was produced. A new module for antenna
precision control was designed and tested: 3AC - Antenna Attitude Automatic
Control, with TELESAL funding. GEM will contribute also to the calibration of the
MWR receiver aboard the JUNO Polar Orbiter planetary spacecraft, which will be
launched in 2010 to Jupiter to monitor the jovian atmosphere through radiometric
analysis in the 1-10GHz band.
PrepSKA:
This project effectively started in late 2008. Preparation for the implementation
plan, concerning: network study and information gathering on best current
technologies for the digital data back haul between telescope stations; and time
and LO distribution; recollection of data on super-low noise pHEMT transistors.
These could be candidates for LNA frontends and IF part of receivers and at the
same time respond to cost issues of mass production of important components for
the Square Kilometer Array.
Instrumentation and Measurement
The Instrumentation and Measurement Group developed in 2008 work that can be
further subdivided in the following topics:
Analogue-to-digital and digital-to-analogue conversion;
Measurement of electrical quantities;
Sensors and transducers;
Signal acquisition and automated and telemetric measuring systems;
266
Signal processing applied to sensors and instrumentation.
In the field of analogue-to-digital (AD) and digital-to-analogue (DA) conversion,
the Instrumentation and Measurement Group continued its collaboration with
IEEE TC-10 Waveform Generation, Measurement and Analysis Committee. Within
this technical committee, GIM members contributed to the work related with IEEE
standards: IEEE1057 (Waveform Digitizers), IEEE 1241 (ADC), and IEEE 1658
(DAC). The work concerned the study of the uncertainty of analog to digital
converter test methods, namely of the Histogram Test Method, the Random Noise
Test Method and the Sine Fitting Test Method and the consideration of different
non-ideal effects like additive noise, jitter, phase noise and harmonic distortion.
In what concerns the measurement of electrical quantities, it should be
emphasized the measurement of power, impedance, and magnetic field, all in the
context of FCT funded projects. The implemented measuring devices and systems
include hardware and software developed in-house both using commercial offthe-shelf products and specially designed products. The targets of the developed
work were, essentially, power quality analysis, magnetic induction tomography,
and non-destructive testing (NDT).
Related to the first of these two subjects, new algorithms for power quality (PQ)
detection, classification and measurement were developed and implemented in a
PC based measurement station and later fully implemented in a commercial DSP
kit. Genetic algorithms were used in sine fitting problems for optimization of the
convergence process. The algorithms were also applied to multi-harmonic signals
and specifically to impedance measurements using tailored multi-harmonic
signals. Previously developed sine fitting and ellipse fitting algorithms were
implemented in a commercial DSP kit for baseline assessment and requirements
definition with the goal of development of a stand-alone DSP based instrument for
impedance measurements.
During 2008 the research on the project on Magnetic Induction Tomography lead
to the construction of a third prototype with a new moving system of sensing coils
and body plate that achieved the required signal to carrier ratio performance to
measure biological tissues. The accuracy and the measurement requirements for
the positioning setup were studied. The new prototype makes possible a ten-fold
improvement in resolution and accuracy, besides speed and stability.
267
The Instrumentation and Measurement Group started to pay particular attention
to non destructive testing using eddy currents in 2008. The mathematical basis of
this methodology is being developed in two parts. In the first part, the physics of
the induction system is simulated in the forward problem either using a numerical
method like the finite element method (FEM) or an artificial intelligent technique
(ANN). The simulated system is used to preview the correspondence between first
order variations in the secondary magnetic field to conductive perturbations in the
conductive body. The second part of this study is the formulation of the inverse
relation of this correspondence in order to reconstruct the conductivity images for
a three dimensional sample object. Since the signal from a deeper voxel is
smaller than surface voxel, measurement noise corrupts more the information
from deeper voxels. However, the relation between the magnetic measurements
and the conductivity distribution is nonlinear. Thus, one way to estimate the
solution is to linearize the forward problem around an initial conductivity
distribution and update the conductivity distribution using a suitable algorithm by
comparing the calculated fields with the measurements. Several algorithms can
be used to minimize the norm of ||S x - b|| when solving for x. These algorithms
must be investigated in order to select the one that provides the best
performance for the problem to be evaluated. The mathematical relation between
the conductivity distribution and the measurements is the backbone of the
imaging algorithm. The use of signal processing techniques to process and
interpret data provided by the sensors was implemented and proved to be very
effective to overcome the poor performance of some of these sensors.
R&D on sensors and transducers was mainly conducted in the context of
environmental and biomedical applications and of non-destructive testing. Worth
mentioning are: static and dynamic characterization of sensors and measurement
system (polarography, heavy metals detectors, turbidity, pH and conductivity
sensors); implementation of a Geographic Information System associated with
water quality and dolphin behavior; determination of atmospheric optical
properties using digital photography; development of a wireless set of physiologic
measuring tools which includes an ECG, a pulse oxymeter and an intra-cardiac
rheography device for measurement of blood flow in and out of the heart;
electromechanical
film
sensors
implementation
for
cardiac
parameters
assessment; indirect estimation of blood pressure using ECG, BCG and PPG
signals and EMFi sensors; asthma triggering condition monitoring using Bluetooth
268
smart sensors and smart phone; design and implementation of inductive and GMR
based sensors for NDT.
All Instrumentation and Measurement Group members have experience and
competence on signal acquisition and automated and telemetric measuring
systems. The Group has been a partner of National Instruments and the expertise
of its members has been used either within the context of R&D projects or within
collaborations with external entities. Examples of the first are the implementation
of:
• signal acquisition systems, namely using NI cRIO technology, for environmental
monitoring applications,
• development of new procedures for online detection of broken bars in induction
machines,
• PDA and mobile phone based instrumentation for medical applications,
• remote transmission solutions based on 802.11 protocol and GPRS technologies,
• systems based on Foundation Fieldbus and HART instrumentation.
In 2008, the following services to external entities were rendered:
• collaboration with the Department of Minas of the Instituto Superior Técnico in
developing measuring systems for soil pollution by petroleum derivates;
• collaboration with the Department of Civil Engineering of Instituto Superior
Técnico in developing a Intelligent Bus Lane system for the city of Lisbon;
• design, specification and testing of an integrated remotely accessible system to
monitor and control the radiofrequency spectrum in Madeira and Oporto for
Autoridade Nacional de Comunicações (ANACOM).
Signal processing is constantly present in modern instrumentation and measuring
systems. As in the past, techniques such as neural networks, self-organizing
maps, fuzzy logic, wavelets, genetic algorithms and data fusion have been used
to digitally process sensors‘ output data for accuracy improvement, data
representation classification and forecasting purposes.

271
Applied Mathematics
Research was developed in the following three important fields of Mathematics:
Optimization.
Numerical Linear Algebra
Partial Differential Equations
Apart from some more theoretical oriented studies, my research has mainly been
focused in the design, convergence analyses, implementation and testing of
algorithms for the solution of many important problems in these areas. I have also
been collaborating with researchers of other areas in the design and solution of
some models of engineering and finance. The most relevant topics are presented
below:
1. Numerical Linear Algebra: Preconditioning and convergence of iterative methods
for the solution of linear systems of equations.
2. Complementarity Problems: design, implementation , convergence analyses and
testing of interior-point algorithms, active-set methods, sequential quadratic
algorithms and enumerative methods.
3. Global Optimization: complementarity algorithms, positive semi-definite and
reformulation-linearization techniques for bilevel programming, quadratic and
bilinear
programming
and
mathematical
programs
with
complementarity
constraints.
4. Discrete Optimization: global optimization algorithms for linear, nonlinear and
complementarity problems with integer variables.
5. Solution of Structured Optimization Models, namely finance portfolio selection
models, network models, eigencomplementarity problems and other engineering
models.
6. Solution of Partial Differential Equations associated with contact problems
and other variational models in engineering.
7. Design and solution of models of filtering and other areas in telecommunications.
Logic and Computation
The Craig interpolation property and the Maehara interpolation were investigated
and several (global and local) preservation results for interpolation are obtained for
fibring logics that fulfill mild requirements.
272
A conservative enrichment of (two-sorted) first-order logic with almosteverywhere quantification was proposed. The completeness of the axiomatization
against the measure-theoretic semantics was carried out using a variant of the
Lindenbaum– Henkin technique. The independence of the axioms was analyzed,
and the almost-everywhere quantifier is compared with related notions of
generalized quantification. A suitable fragment of the logic is translated to firstorder logic and validity is shown to be preserved.
Heterogeneous fibring, allowing the original logics to have different
presentations (e.g. one presented by a Hilbert calculus and the other by a sequent
calculus), has been an open problem. Consequence systems were shown to be a
good solution for heterogeneous fibring when one of the logics is presented in a
semantic way and the other by a calculus and also a solution for the heterogeneous
fibring of calculi.
New characterizations of computable analysis with real function algebras
were devised, where the algebras are closed under, alternatively, inversion,
minimalization or the operation that solves general ordinary differential equations.
The model of computation based on polynomial differential equations developed
earlier was refined, and several bounds for that model when its parameters are
restricted to being computable and comparable were established. Specifically,
universality results, robustness results as well as undecidability results were proved
for the class of polynomial ODEs whose parameters belong to Q[Pi].

This project intends to optimize several video encoding parameters.
Although we focus on ITU-T H.264/MPEG-4 AVC standard as a
reference to formulate the problems, all the optimization solutions
to be investigated have a more general application. As it is well
known, a standard like H.264 is a compilation of the most
277
sophisticated algorithms. Despite each of them by itself is qualified
as of a high performance, their combination may result in a poor
system. For instance, a standard could provide either less or better
performance in some circumstances like constant/variable bit rate
(BR), low/high BR, low/high resolution, low/high scalability,
good/bad channel, low/high delay, etc. Therefore, parameter tuning
is of crucial importance to adapt the standard to any of those
conditions. Moreover, in general, when a new standard is issued, it
provides a worse performance than any previous one since it lacks
optimization. This is the case of H.264, a recent ITU/MPEG standard
with some profiles still to be approved. As the history showed, we
then expect, in the ORAL framework, to contribute to improve H.264
performance significantly. The main motivation to embrace this
proposed research is to join, in a fruitful manner, scientists from
mathematics and communications to solve multidimensional telecom
problems. The optimization problems to be processed are largescale and involve constraints. Furthermore, interpolation, stability,
existence, achievability and convergence rate are critical
mathematical concepts that are fundamental in this research. Let
Xijk be a random process defining an original sample (image pixel)
at spatio-temporal position i,j,k of video sequence length T and
image resolution NxM.
We intend to propose new mathematical methods for those specific
problems in order to achieve optimal and sub-optimal solutions with
as low computational complexity as possible. These new
methodologies are to be compared with other solution methods that
have been published in the literature.

The main objective of this project is to develop an electric drive,
based on matrix converters, with self-diagnostic and fault-tolerant
capabilities. The drive, which will rely on the use of induction motors
and PMSMs, will allow to detect and locate any fault in the matrix
converter. After its detection, the control system of the drive will
enter in a fault-tolerant operating mode, according to which the
control
strategy
will
be
modified
in
order
to
minimize
the
consequences of the fault and thus maintaining the system running,
although with degraded performance.
Besides the detection of faults in the matrix converter, and in the
case of the induction motor drive, the integrated diagnostic system
should also be able to detect faults in the motor, namely stator and
rotor faults, bearing faults and airgap eccentricity.
The
drive
obtained

advantages of the matrix converter with the high reliability granted

Title
Flaw Imaging in Metals by Contactless Conductivity
Funding
FCT/PTDC
Descript.
The measuring principle is based on the phenomenon whereby the
impedance of a coil generating a time-varying magnetic field
changes in the presence of a conductive material as eddy currents
are induced in the material. Therefore the idea of a contactless
electrical conductivity imaging system (CECIS) is based on a sensor
composed of two coils. One of the coils, designated the transmitter
coil, is driven by an alternating current and generates an oscillating
magnetic field that induces currents inside the object to be tested.
These induced currents are related to the conductivity distribution of
the body. Another coil, the receiver coil, measures the total
magnetic field. One component of the magnetic field is related to
the primary imposed currents and the other component is related to
the induced eddy currents. As the signal originated from deeper
voxel significantly attenuates before it reaches the receiving coil the
information gets easily corrupted by measurement noise. By
incorporating into the design a real time digital signal processor able
to perform advanced signal processing techniques it is possible to
increase significantly the range of the sensor. Two solutions are
envisaged to accumulate data either by relocating the probe several
times using a XY scanning mechanism or by using an array of
sensors, i. e., several probes in the vicinity of the object to be
tested.
The mathematical basis of this methodology is developed in two
parts. In the first part, the physics of the induction system is
simulated in the forward problem either using a numerical method
like the finite element method (FEM) or an artificial intelligent
technique (ANN). The simulated system is used to preview the
correspondence between first order variations in the secondary
magnetic field to conductive perturbations in the conductive body. A
283
set of equations in the discrete form can be formulated: Sx=b,
where x is the unknown conductivity perturbation vector, b is the
magnetic field measurement vector and S is the sensitivity matrix.
The second part of this study is the formulation of the inverse
relation
of
this
correspondence
in
order
to
reconstruct
the
conductivity images for a three dimensional sample object: b=S x +
y, where y represents unknown measurement noise present in the
real scenario. Since the signal from a deeper voxel is smaller than
surface voxel, measurement noise corrupts more the information
from deeper voxels. However, the relation between the magnetic
measurements and the conductivity distribution is nonlinear. Thus,
one way to estimate the solution is to linearize the forward problem
around
an
initial
conductivity
distribution
and
update
the
conductivity distribution using a suitable algorithm by comparing the
calculated fields with the measurements. Several algorithms can be
used to minimize the norm of ||S x - b|| when solving for x. These
algorithms must be investigated in order to select the one that
provides the best performance for the problem to be evaluated. The
mathematical relation between the conductivity distribution and the
measurements is the backbone of the imaging algorithm.

The concept involves parabolic dishes with innovative feeds to

lower frequencies phased arrays can become cost-effective and
offer new operational capabilities. Technological innovation, closely
paralleling commercial IT developments, is the key to the design
concepts under investigation and to the target cost of 1.5 billion

Detection, Classification and Estimation of Defects in Metallic Plates

Descript.
Non destructive testing (NDT) is of paramount importance for
ensuring the integrity of materials. Eddy currents testing (ECT) is
one of several methods like, remote field testing (RFT), flux leakage
and Barkhausen noise, that use electromagnetic theory to examine
conducting materials. It is a particularly attractive test because it
offers both very high detectability and high scanning speeds.
Besides direct contact with the test material is not necessary.
Nowadays, with the use of microprocessor based measuring
instruments, the potential and user-friendliness of eddy currents
testing has been greatly enhanced. The role of the computer has
two different components: one related with the possibility to
automate the measuring system (data acquisition control, data
processing, signal classification and displaying) and other with
numerical
modeling
of
the
testing
process.
The
computing
capabilities are used to quantitatively predict eddy current signals
for realistic situations and to evaluate crack profiles from testing
signals by solving the inverse problem of the physical phenomenon
under test. At this time the tasks related to the data acquisition,
signal processing and graphical representation, are already under
way, with some work already published [1-6,8,9]. The point is that
the inverse problem of computing the crack profiles from the eddy
currents data is ill-posed, i.e., the crack profiles are not univocally
determined by the measured eddy currents. A possible approach to
mitigate the ill-posedness nature of this inverse problem is to
classify the crack profiles according to the different types of
292
material defects. The idea is to exploit the a priori knowledge of the
problem and thus select the proper defect model. In order to
investigate the assumptions of the technique, particularly, patterns
identification,
