1. INTRODUÇÃO
1.1 Resenha histórica
O “Instituto de Telecomunicações” (IT) é uma instituição privada sem fins lucrativos
resultante da associação de quatro instituições com experiência e tradições na
investigação e desenvolvimento na área das telecomunicações:
• “Instituto Superior Técnico” (IST);
• “Universidade de Aveiro” (UA);
• “Faculdade de Ciências e Tecnologia da Universidade de Coimbra” (FCTUC);
• "Portugal Telecom Inovação", (PTI), ex. "Centro de Estudos de Telecomunicações"
(CET),
a
unidade
de
investigação
e
desenvolvimento
do
operador
de
telecomunicações incumbente “Portugal Telecom” (PT).
O IT está organizado em três pólos: um em Aveiro, no Campus Universitário da
Universidade de Aveiro, outro em Coimbra no Pólo II da Universidade de Coimbra e
um terceiro em Lisboa, no IST.
A constituição do IT beneficiou do apoio do programa CIENCIA, num montante total de
1,5 milhões de contos, através de três contratos celebrados em 1991, com as
instituições associadas. Este financiamento permitiu a construção de infraestruturas
nos três Pólos e a aquisição de equipamentos para os respectivos laboratórios.
As instalações ficaram concluídas em 1993 no Pólo de Aveiro e em 1994 nos pólos de
Coimbra e Lisboa. Nesse sentido pode-se considerar que, desde 1995, o IT desenvolve
uma
actividade
em
regime normal. Resumem-se,
em
seguida, algumas das
actividades mais marcantes realizadas em, ficando os detalhes para os relatórios das
áreas temáticas e dos grupos de investigação.

1.2 Gestão
O IT é gerido por uma Comissão Executiva e por Comissões de Gestão, em cada pólo,
que incluem os membros da Comissão Executiva do pólo. As comissões de gestão
dispões de ampla autonomia para a gestão corrente. A Comissão Executiva reúne-se
pelo menos uma vez por mês.
A actividade científica do IT é supervisionada pelo Conselho Científico que reúne pelo
menos duas vezes por ano. Uma para apreciar a proposta de Plano de Trabalhos e
Orçamento e outra dar parecer sobre a proposta de Relatório de Actividades. O
Conselho Cientifico poderá ainda reunir para apreciar qualquer outro assunto que lhe
seja submetido pela Comissão Executiva .
As propostas de Plano de Actividades e Orçamento e Relatório de Actividades e de
Contas (estas depois de certificadas) são submetidos à Assembleia Geral para
aprovação.
O Plano de Actividades e o Relatório de Actividades são ainda apreciados pelo
Conselho Consultivo que sobre eles emite parecer detalhado.
No ano de 2001 foram realizados as seguintes reuniões:
• duas reuniões da Assembleia Geral, uma em 30m de Maio , em Lisboa, para
aprovar o Relatório de Actividades e Contas e para eleger os membros da
Assembleia Geral, do Conselho Fiscal e da Comissão Executiva e outra em 14 de
Dezembro, em Lisboa, para aprovar o Plano e Orçamento para 2001;
• reuniões mensais da Comissão Executiva e das Comissões de Gestão dos pólos;
• uma reunião com o Conselho Consultivo, formado por três especialistas no campo
das telecomunicações (Dr. Roland Hüber, Prof. John O’Reilly e Prof. Martin
Tomlinson) actuando em nome individual, que em Abril estiveram presentes
durante a ConfTele 2001 e analisaram detalhadamente as actividades do IT em
2000 e apresentaram recomendações sobre as propostas para 2001;
• duas reuniões do Conselho Científico, uma em 26 de Março, em Coimbra (S.
Marcos) para discutir o Relatório de Actividades de 2000, e outra em 29 de
7
Novembro em Vila Franca de Xira, para discutir a proposta de Plano de Actividades
e Orçamento para 2001 a submeter a Assembleia Geral e ainda para discutir as
consequências para o IT do estatuto de laboratório associado , recentemente
concedido.
Tal como previsto no Relatório de Actividades de 2000, em 23 de Novembro de 2001,
foi concedido ao IT, o estatuto de laboratório associado. Embora esta decisão fosse
esperada, ela foi conhecida tardiamente (meados de Novembro) pelo que o Plano de
Actividades e Orçamento para 2002 não incluíram todas as consequências deste novo
estatuto.
Na sequência de longas discussões internas sobre a “Análise Estratégica” no ano de
2000 o IT tomou, em 13 de Fevereiro, em Tomar, a decisão formal de iniciar uma
reestruturação interna segundo três áreas temáticas multi-disciplinares:
• Comunicações rádio
• Comunicações ópticas
• Redes e Multimédia
e uma área horizontal de Ciências Básicas e Tecnologias de Suporte.
No ano de 2001 as receitas de exploração totalizaram 1228 k€ com a seguinte repartição:
•
prestação de serviços:
557k€
•
subsídios a exploração
456k€
•
outros
215k€
A redução dos subsídios à exploração foi muito significativa, de 2000 para 2001. A
ligeira redução das receitas de exploração ficou a dever-se a um acréscimo substancial
da prestação de serviços.
Na prestação de serviços
8
salientam-se os seguintes clientes:
•
PT Inovação
•
Marinha Portuguesa
Do total da prestação de serviços 80k€ são resultantes de acções de divulgação e
formação avançada.

1.3 Eventos mais importante em 2001
Em 23 de 24 de Abril, na Figueira da Foz, realizou-se a 3ª Conferência de
Telecomunicações, ConfTele 2001, que reuniu mais de 250 participantes. As actas
publicadas incluem 128 comunicações.
Em 23 de Novembro foi concedido ao IT o estatuto de Laboratório Associado. À data o
IT era o único laboratório associado na área das telecomunicações. Este novo estatuto
corresponde a um aumento significativo de financiamento, essencialmente destinado a
contratar investigadores doutorados e alguns técnicos. De acordo com o acordo
assinado o IT poderá contratar, em 2002, 3 novos técnicos e 4 investigadores
doutorados. Estes números aumentam anualmente e atingem 6 técnicos e 22
investigadores doutorados em 2006.
Iniciaram-se alguns, poucos, projectos novos com financiamento nacional. A maioria
dos projectos em curso são financiados pela FCT. Entre as excepções destacam-se 11
projectos financiados pela PT Inovação, um projecto de dimensões consideráveis
financiado pela Agência Espacial Europeia (ESA) e alguns pequenos projectos
financiados pela indústria nacional.
Tal com em anos anteriores a participação de investigadores do IT em projectos
financiados pela Comissão Europeia foi, quase sem excepção, realizada através das
instituições associadas, devido às actuais Regras de Participação.

1.4 Recursos Humanos e Produção Científica
No dia 31 de Dezembro o IT incluía 134 investigadores dos quais 95 doutorados e
enquadrava 71 alunos de doutoramento, 77 alunos de mestrado e 116 alunos de
licenciatura (em trabalho final de curso). A Tabela 1 apresente a distribuição de

2. INTRODUCTION
1.1 History
“Instituto de Telecomunicações” (IT) is a private, not-for-profit organisation, an association of four 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", (PTI), ex "Centro de Estudos de Telecomunicações"
(CET), the research unit of the incumbent telecommunications operator “Portugal
Telecom” (PT).
IT is organised around three sites: one in Aveiro, in the University Campus, another in
Coimbra, in Pole II of the University of Coimbra and the third one in Lisbon, in IST.
Setting up of IT was the result of a 1.5 billion escudos grant from Programme CIENCIA, through three contracts signed in 1991. This investment enabled new infrastructures to be built and research laboratories to be equipped in each site.
Buildings were concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since
1995 IT activities proceed regularly. Key developments in 2001 are sketched below
leaving the details for the report of the research groups.
16
1.2 Management
IT is managed by an Executive Board, and by site management boards, which include
the site members of the Executive Board. Site management boards enjoy ample
freedom to deal with current affairs. The Executive Board and site management
boards meet at least once a month.
IT scientific activities are overseen by the Scientific Board, which meets twice a year
to comment on the Work Plan and Budget, on the Annual Report and on any other
subject put forward by the Executive Board. The Work Plan with the Budget and the
Annual Report and Accounts (after legal certification) are subsequently submitted to
the General Assembly for approval.
IT Work Plan and the Annual Report are discussed with the Advisory Committee.
During 2001 the following meetings were held:
• two meetings of the General Assembly one on the 30th of March, in Lisbon, to
approve the “2000 Annual Report” and to elect the members for the General
Assembly, the Audit Board and the Executive Board, and another on the 14th of
December, in Lisbon, to approve the “Plan and Budget for 2000”;
• monthly meetings of the Executive Board and site management boards;
• one meeting with the Advisory Committee, formed by three independent experts in
the field of Telecommunications (Dr. Roland Hüber, Prof. John O’Reilly and Prof.
Martin Tomlinson) acting in a personal capacity who, in April, were present during
ConfTele 2001, carried out a detailed survey of IT activities during 2000 and
proposals for 2001, and issued recommendations for future activities;
• two meetings of the Scientific Board, one on the 26th of March, in Coimbra (S.
Marcos), to discuss the 2000 Annual Report, and another on the 29th of November,
in Vila Franca de Xira, to discuss the “Plan and Budget for 2002”, to be submitted
to the General Assembly, to discuss the consequences of IT newly acquired status
as “Associated Laboratory”.
As foreseen in the IT Annual Report –2000, IT was awarded the status of “Associated
Laboratory” , on the 23rd of November 2001. Although this was to be expected, the
decision came rather late (mid November) and IT Plan and Budget for 2002, could not
possibly include all consequences of this decision.
17
Following lengthy internal discussions on the “Strategic Review” in 2000, in a one day
meeting which took place on the 13th of February, in Tomar, IT decided to start an
internal re-organisation along three multidisciplinary thematic areas:
•
Wireless Communications
•
Optical Communications
•
Networks and Multimedia
and an horizontal area on Basic Sciences and Enabling Technologies.
During 2001 income totalled 1228 k€ distributed as follows:
•
services:
557 k€
•
subsidies
456 k€
•
other:
215 k€
The reduction in the amount of subsidies from 2000 to 2001 was rather sharp. The
slight reduction of income was due to a substantial increase in services.
The main clients were:
•
PT Inovação
•
Portuguese Navy
The main sources of subsidies were:
•
Fundação para a Ciência e Tecnologia
•
European Union
50 k€
•
European Space Agency

1.3 Highlights of 2001
In April, 23 and 24, in Figueira da Foz, took place the 3rd Conference on
Telecommunications, ConfTele 2001, which attracted more than 250 participants. The
published proceedings (in English) include 128 papers.
On the 23 rd of November, IT was awarded the status of “Associated Laboratory” at
the time the only of such units in the field of telecommunications. This newly acquired
status brings along a substantial increase in funding, mostly for hiring post doctoral
researchers and some technicians. According to the agreement signed IT will be able
to hire in 2002, 3 new technicians and 4 new post doctoral researchers. These
numbers increase every year and will reach 6 technicians and 22 post doctoral
researchers by 2006.
A few new nationally funded projects were started in 2001, mostly funded by FCT.
Among the few exceptions there are 11 projects funded by Portugal Telecom
19
Inovação, a fairly large project funded by the European Space Agency, a few small
projects funded by national industry.
As in previous years involvement of IT researchers in European Commission funded
projects were almost without exception carried out through IT associated due to the
current rules for participation.
1.4 Human Resources and Scientific Output
On the 31st of December IT had 134 researchers of which 95 hold a Ph.D and suported
the research activities of
71 Ph.D. students, 76 M.SC. students and 116 graduate
students (for their final year project). The distribution of human resources among the
three sites is shown in Table 1.

To reflect the IT 2001 activity some tangible objectives were defined in the Work
Programme and Budget for 2001. As shown in the Table 2 below most of these
objectives were met or exceeded. In fact this would be strictly true if submitted thesis
were accounted for as approved.
During 2001 four patents with IT researchers as authors, were awarded, or deposited.

RESEARCH ACTIVITIES
2.1. Optical Communications
Optical components and sub-systems
The research activity was focused on:
•
the development of mathematical modelling tools regarding opto-electronic
devices operation, namely: the analysis of wave propagation in periodic
structures using the coupled wave theory or the matrix techniques for multisection FP, DFB or DBR laser structures; photodetector modelling; and
modelling and characterisation of optical transceiver modules working as endcomponents in a point to point WDM access network;
•
the modelling, analysis, design optimisation and implementation of optical
devices (lasers, modulators, detectors, dielectric optical filters, speciality fibres,
etc.);
•
the modelling and implementation of negative induced Bragg gratings,
exploring the possibilities to implement and control their formation, backing up
the experiments with deep theoretical modelling and simulation;
•
the study of the amplification in the L band for expansion of the amplification
band in the fibers, modelling and sometimes implementing several approches,
like Raman and erbium, in some configurations in order to compare them
under traffic constrains;
•
the investigation of new effects of chiral materials for application to optical
fibers: from the designer's point of view, chiral optical fibers may increase the
flexibility in optimization procedures due to the extra chirality parameter. The
study of the leakage effect associated with semi-leaky modes in open dielectric
chirowaveguides, suited for applications at optical and sub-optical frequencies,
was pursued. Semi-leaky modes have also been studied in dielectric planar
chirowaveguides.
22
Optical communication systems
The work carried out was focused mainly in the following points:
•
development of tools for performance evaluation of optically amplified systems
with arbitrary optical filtering;
•
optimisation of uniform and apodized fibre Bragg gratings for optical filtering in
dense wavelength division multiplexing (DWDM) systems;
•
comparison of performance in anomalous and normal propagation regimes of
dispersion supported transmission technique;
•
optimisation of laser design for use in directly modulated transmission
systems;
•
study of optical single sideband transmission techniques (SSB) in order to
improve the spectral efficiency in fibre networks and the viability of this
transmission scheme for forthcoming networks;
•
study of WDM soliton communication systems in what concerns with the
combined use of dispersion management with in-line control, the problem of
soliton switching in WDM soliton communication systems and a new kind of
fiber solitons, temporal solitons in chiral optical fibers.
Optical networking
The work carried out comprised:
•
studies on topology, performance analysis and design of optical transport
networks taking into account the constraints due to the physical layer (optical
fibre, optical components) and the upper layer protocols to be serviced;
•
the planning of SDH networks and the interaction between SDH and optical
protection;
•
the investigation of different optical network architectures using wavelength
division multiplexing techniques, including optical wavelength converters,
reconversion of multiple wavelength codes (like the ones from OCDMA) and
add-drop multiplexers to be used in all optical networks;
•
the study, modelling and testing of the capabilities of the asyncronous
monitoring of the Q factor of optical networks with the objective of reaching a
stable model for bitrate/format transparent optical monitoring without any
23
frame demultiplexing, simplifying in this way the performance evaluation of
optical networks.
24
2.2. Wireless Communications

from UMTS to future Mobile Broadband Systems.
Coding and Modulation Techniques
Development of new coding and modulation techniques for 3G and 4G mobile
communication systems.
Channel Estimation in Mobile Communications
This research aims at new algorithms for joint channel and clock estimation, and
symbol detection, based on stochastic nonlinear filtering.
We exploit a model-based Bayesian approach, namely by considering the emitterreceiver dynamics model.
Adaptive algorithms able to cope with highly accelerate dynamics, specially with
maneuvers, are currently being developed. Applications of this perspective include
OFDM and CDMA systems, and LEO satellite communications.
Importance Sampling
This topic deals with the performance assessment of digital phase detectors with
carrier phase tracking using importance sampling techniques. Large deviations
approach and adaptive methodologies are being considered. These approaches allow
remarkable simulation time gains, with respect to conventional Monte-Carlo methods.
Positioning and Navigation using Differential GPS
The main interest lies on exploiting the carrier phase information to perform high
accuracy positioning and navigation.
Phase ambiguity resolution is approached as a Bayesian nonlinear filtering problem
involving multi-modal probability density functions.
Applications
of
this
work
include
precision
landing,
docking,
and
attitude
determination.
27
Synthetic Aperture Imaging
This area addresses several important topics related to synthetic aperture imaging.
Namely, we focus on image formation models of moving targets using a single
antenna, aiming at the resolution of the so-called "blind angle ambiguity" problem.
Another issue is the absolute phase estimation for interferometric radar imaging, for
which we adopt a Bayesian approach and develop efficient algorithms.
Finally, we are also interested in techniques for filtering speckle noise from synthetic
aperture
radar
(SAR)
images,
using
Markov
random
fields
and
wavelet
representations.
Hyperspectral Imaging
Concerning
hyperspectral
imaging
(HI),
we
address
three
central
problems:
classification, detection, and unmixing. The main difficulty in all these problems is that
the observation model is a priori unknown. Most of the work we have done has been
on the linear unmixing problem. In addition to the importance it has per se, its
solution will also contribute to the solution of the two other problems. We have been
mainly exploiting independent component analysis techniques.

2.3. Networks & Multimedia
Architectures for Quality of Service (QoS) Provisioning in IP Networks
The objective of the research topic is the development of architectures and
mechanisms for network layer operation in such a way that a service provider be able
to offer to the end users (applications) a transfer service with quantitative
characteristics (delay, bandwidth, jitter) guaranteed to fall within ranges defined at
the outset of the provision of the service.
BGP and routing under path choice policies
BGP is the only inter-domain routing protocol of the Internet. BGP is a path-vector
protocol. The distinguishing features of these protocols is the possibility to choose
routing paths which take into account the commercial relationships between domains.
However, this advantage may bring along problems of convergence. The objective of
the research topic is to investigate conditions for the convergence of path-vector
routing protocols.
Traffic and Congestion Control
The role of traffic control in current networks is growing due to the need for providing
different quality of service to multimedia applications. From the network point of view,
congestion avoidance is an important mechanism that needs to be implemented to
prevent the collapse of the infrastructure. From the applications point of view, the
generated traffic, to be carried by the network, can be shaped to cope with network
conditions while keeping acceptable quality at the end user. The work on this topic
comprises mostly techniques for the determination of the congestion status by the
routers at the core of the network, transfer of this information to the end users, and
the control algorithms to shape end user traffic in order to avoid network congestion.
Transport architecture for satellite networks
In today’s Internet, reliable end-to-end transport is provided by the TCP protocol. This
protocol presents severe performance problems when operated over links with high
packet loss due to bit errors or channel fading, long propagation delays, or
asymmetrical forward and return bandwidths. These unfavourable characteristics can
29
be simultaneously present on a satellite link, and thus TCP can present very poor
performance on connections traversing such links. The objective of the research topic
is the development of architectures and protocols for end-to-end reliable transfer
allowing the efficient use of satellite links
Traffic Modeling and Estimation
The statistical characterisation of real telecommunications traffic is crucial for the
design and operation of multiservice networks. This characterisation involves both the
adoption/development of models and the estimation of the correspondent parameters
to
match
observed
traffic.
The
studies
require
extensive
internet
traffic
measurements, and performance predictions are to be compared with the current
network behavior. In particular, we research traffic models and parameter estimation
procedures for ATM, MPLS and IP traffic, with emphasis on MMDP, MMPP, CMPP,
BMAP, Self-Similar and Multi-Fractal models. We investigate the impact in terms of the
network performance of various traffic characteristics, e.g., the autocorrelation and
the probability function of the packet arrival rate and the packet size distribution.
Network Dimensioning
The main aim of this research area is the search of linear integer programming models
for dimensioning multi-service networks (e.g. MPLS) and the investigation of suitable
solution techniques. A significant set of dimensioning problems to be addressed is on
network link capacity dimensioning to support explicit unicast routing, destination
based unicast routing (e.g. OSPF and IS-IS), multicast routing, retrieval services,
hierarchical logical networks, network survivability, simultaneous consideration of flow
level and packet level constraints. Two additional problems will be also addressed: (i)
node dimensioning considering equipment existence and equipment transfer costs and
(ii) multi-layer dimensioning of MPLS over WDM networks. Depending on the
problems, solution techniques are being investigated in two domains: (i) through the
search of heuristics (e.g. greedy based algorithms and Lagrangean relaxation
algorithms) and meta-heuristics (e.g. genetic algorithms) and (ii) through valid
reformulations that strength the linear relaxation of the dimensioning models. For the
first class of solution techniques, suitable cut-sets that enable the calculation of good
lower bounds will be investigated in order to access the quality of the solutions found.
30
Flow Aggregation and Scalable Admission Control
The aim of this area is to research probing based admission control for DiffServ
networks, in particular, techniques to overcome the so-called resource stealing
problem. We also investigate the impact of flow aggregation on the signaling load of
core networks and of the trade-offs between signaling and resource utilization.
Access Network Architectures
Research on new architectures, traffic management procedures and protocols for
future IP based access networks supporting multimedia communications. New
emergent protocols allow innovative approach for network access solutions breaking
links with the past. Theoretical studies and demonstrations are needed to identify
viable solutions for next generation networks based on IP (or IP evolution).
Telecommunications and Society
Creating awareness about the impact of recent telecommunications developments at
the level of the individual, organizations and society.
Techno-Economic Assessment of Multimedia Networks and Services
Analysis and evaluation of network solutions and deployment scenaria for the
provision of multimedia communication services.
Public Network Evolution
Study of scenarios and protocols for public network evolution converging to an IP
based infrastructure. Starting from the nowadays public infrastructure and available
specific protocols, a clarification of possible solutions and its interaction will be
studied. Requirements for network evolution and for harmonization of possible
solutions implementations will be also established.
Advanced Services over IP Networks
This area is centered on the problems of providing mobility and QoS advanced
services over non-uniform IP networks. Non-uniform environments are characterized
by different aspects: (i) different administrative domains, (ii) different transmission
31
technologies, (iii) different IPv4-IPv6 transition scenarios (iv) or mobile environments
with variyng characteristics. The following topics are addressed: (i) Network support
for QoS, especially on wireless environments. These activities will cover protocol
optimization and development, and IP over “wireless” mappings/interfacing; (ii) QoSenabled service support. This activity will cover QoS management (bandwidth broker
strategies), AAA support in MIP QoS environments, and SLAs to SLS mappings,
focusing on mobile environments; (iii) Mobile IP over IPv4-IPv6 transition scenarios.
This activity will cover the identification of the problems in the implementation of
present RFCs implementations and proposals for solutions.
Architectures and Tecnhologies for Network and Service Management
Research on new software approaches and techniques for network and service
management. Issues such as QoS, service level agreements (SLAs), resource
configuration and monitoring, security, new IP protocols (e.g. SIP) and technologies
(e.g. IP DiffServ, MPLS), IP VPNs,...are of interest to this subject.
Unsupervised Learning
In this research area we focus on new criteria and algorithms for unsupervised
learning, including unsupervised classification (clustering) and mixture-based density
estimation.
Central issues addressed are: model selection, combination of models, feature
selection for unsupervised learning.
Sparseness in Supervised Learning
In this research area we consider algorithms for supervised learning (including
classification/detection and regression).
We are developing a Bayesian approach to inducing sparseness, which allows for
integrating feature selection into the learning algorithms. A main feature of the
developed methodology is its adaptiveness.
Image Compression Using Independent Component Analysis
We are currently studying the feasibility of image compression algorithms based on
independent component analysis. In this approach, the images are decomposed into
32
bases that are learned, rather than fixed a priori (like the DCT or wavelets), thus
leading to sparser representations.
Wavelet Based Image Deconvoltion
Our interest here is to extend wavelet based image models, which typically only allow
exploiting their full power in image estimation problems, to image deconvolution
scenarios.
We propose algorithms that combine the efficient image representations offered by
wavelet transforms with the diagonalization of the convolution operator provided by
the discrete Fourier transform.
Robust Video Coding
Unlike with data, real time video retransmission to ensure error-free delivery might be
unacceptable due to delay sensitivity. Extensive use of entropy coding in video coding
renders compressed video specially vulnerable to errors. The objective is to design
strategies at the source encoder and decoder to ensure reliable transmission at very
low bit rate.
Robust Speech Recognition
The aim of this topic of research is to enhance the performance of recognizers, namely
by reducing intra speaker, inter speaker and environment variability of speech signals.
Research is carried out on vocal tract length normalization procedures (VTLN) based
on the information of the speaker's pitch, in order to segregate male and female
speakers without duplicate models for those categories.

and characterization of electronic and opto-electronic devices and systems, such as
LEDs and LED active matrices, and FETs.

for sensor components. Polymer gel electrolytes were used as reference electrolytes in
thin film (solid state) reference electrodes for medical applications. Polyimide thin
films were used as humidity sensitive elements for integrated (on chip) microsensors.
Molecular based conductors
Characterization of crystalline organic conductors of the charge transfer salt and
molecular type. The research activity, in 2001, consisted on the characterization by
Electron Spin Resonance spectroscopy of new materials and study of the correlation
between molecular and crystalline structure and electrical and magnetic properties. A
molecular conductor based on a neutral molecular entity was obtained for the first
time (worldwide).
IC Circuits and Systems
Design of analog and mixed-mode integrated circuits and systems with application in
Telecommunications, namely fast front ends for optical communications and access
interfaces for communications. Accessorily, development of related technologies, such
as scientific instrumentation.
Analogue-to-digital conversion modelling and testing
New methods to obtain the static and the dynamic transfer function of ADCs, using the
histogram method over sinusoidal and/or gaussian noise and small amplitude waves,
as the stimulus signal were investigated. The transfer function was used to derive
34
merit figures like INL, DNL, SNDR, THD and the effective number of bits of the
converters. A new mixed frequency-domain (FFT) and time-domain (sine fitting)
dynamic testing technique to obtain the transfer function of converters, including
those who show hysteresis, was developed. This lead to a completely new procedure
that can overcome the limitations of the traditional testing methods. Intercomparation
of different ADC characterisation standards was performed.
Measurement of electric quantities
The development of an impedance measurement system based on self-adjusted
measurement bridges continued. The accuraccy of the measurement system was
largelly improved by using sine-fitting algoritms to recover very noisy signals. A new
procedure to compute the initial values for the four parameters sine-fitting algorithms,
now ready for standardization was developed. This new procedure grants convergence
of the algorithm, even in those cases where the traditional techniques tend to
converge to local minimums of the error function.
Measurement of non-electric quantities: sensors and transducers
The assessment of different parameters that reflect water and air quality was carried
out. Several commercial sensors were tested, evaluated and upgraded. For air, a
smart sensor using a tin dioxine (SnO2) sensing unit was designed. An additional
system for sensor calibration in the laboratory was implemented with several
disturbance
quantities
being
simulated.
For
water,
different
turbidity
sensing
architectures were designed and tested. Experimental studies on the behaviour of the
emitters (IR LEDS and laser diodes) and receivers (photodiodes) used in the turbidity
sensors were carried out. A linear pixel array displacement sensor with tilt angle
correction capability was designed and implemented.
Data acquisition and processing
Different DAQ and
GPIB
solutions for data acquisition and processing were
implemented in order to calibrate and test the following sensors: displacement optical
sensors based on linear pixel array; gas (CO) concentration; solvent vapors; turbidity,
temperature and pH. As processing components, several neural network architectures
(MLP, RBF) were designed, tested and implemented in order to increase system
accuracy, diminishing the disturbance factors influence (i.e., temperature, humidity).
Considering that some sensors have a non-linear characteristic, two versions of a non35
linear analog-to-digital
conversion
structure
(DIO
PORT-DAQ
and
DIO
PORT-
microcontroler) were designed, implemented and tested in particular applications
(smart gas sensor, smart temperature sensor). The implementation of a Smart
Transducer Interface Module to measure ph and temperature based on Std. 1451 was
carried out. A Network Capable Application Processor emulator based on a PC using
the Centronics digital interface and LabView as a software component was developed.

libraries of programmable matrix arrangements based on NMOS structures, to
implement the required functions towards power conversion and power amplification,
by means of convenient metal layers interconnections; (b) provide circuit topologies,
that implement required functions, handling high voltages, to control, drive, sense and
protect devices, resorting, exclusively, to NMOS structures; (c) optimise LDSD and
LDD NMOS transistors, increasing breakdown voltage up to 50V, using a submicron
standard CMOS technology, through the use of new devices (GSLDD and GSLDSD);
(d) decrease significantly low series production cost; (e) reduce turn-around
production cycle; and (f) enable the reuse of functional blocks. The same methodology
can also be applied to sophisticated Smart Power technologies, for fast prototyping.

DSP-Based Winding Fault Diagnosis in Operating Three-Phase Power
Transformers
The major aim of this work basically comprises the development of a prototype, able
to provide a complete and reliable diagnosis of the operating condition of three-phase
power transformers, particularly regarding the occurrence of winding faults. For that
purpose, a modelling and simulation study was conducted, concerning either the
normal operation or the failure mode behaviour of three-phase power transformers, in
order to provide an evaluation of the suitability of diagnostic techniques, which can be
applied without taking transformers out of service and which can also provide a fault
severity criteria. The experimental validation work was also already performed. The
on-going

mainly
related
to

Condition Monitoring and Diagnostics of Switched Mode Power Supplies
This work is intended to explore adequate strategies for diagnosing the occurrence of
faults in telecommunications power supply systems. The ultimate purpose is to include
the diagnostic routines into the control module, therefore allowing for the introduction
of remedial control strategies soon after failure occurrence and thereby improving
reliability and maintainability. In other words it is envisaged the development of fault
tolerant telecommunications energy systems. Outside of the large switching centers,
the switched mode rectifier/charger rules, since it is ideally suited for the low power
requirements and the potentially harsher environment. In almost all of these type of
systems the location is unmanned; so reliability, fault tolerance, repairability and
monitoring are important. For that purposes, a modelling and simulation study was
conducted, concerning the normal operation of switched mode power supplies. The
failure mode behaviour is now being investigated in order to allow for the evaluation
of the fault tolerant strategies that can be adopted against a complete system failure.

Objectives
The Image Group has the objective of developing technology in the areas of visual
information analysis, modelling, processing, manipulation, representation, coding and
description. These technologies have assumed growing importance in the past years
with the digitisation of audiovisual communications and the consideration of new
requirements such as interactivity and synthetic and natural content integration.
50
Due to the importance of the interoperability requirement in the context of audiovisual
services, the Image Group has since the very beginning considered as essential the
pro-active
participation
in
the
most
important
audiovisual
representation
standardisation body: ISO MPEG. Also the participation in national and international
research and development projects is a major target of the group. In fact, the Image
Group continuously tries to find the best balance between academic, project and
standardisation activities.

Objectives
The research and development activities of the Optical Communications Group span a
broad band of subjects. Among these are:
- High speed point-to-point transmission, with bit rates from 10 to 40 Gbit/s per
channel, including signal processing like line coding, single sideband modulation,
electrical and adaptative equalisation.
- Dense wavelength division multiplexing; WDM transmission over 500-1,000 km with
an aggregate capacity around 1 Tbit/s is being investigated with a return-to-zero
signal format and dispersion management. Different network architectures using all
optical wavelength converters are under investigation.
- Optical networking; optimisation of fibre Bragg grating filters, optical add-drop
multiplexers and crossconnects.
The collaborators of this Group also contribute significantly in advanced signal
processing for other transmission schemes, with emphasis on the next generations of
mobile communications.

Objectives
The members of the electronic and optoelectronic components group plan their activity
in the medium and long term according to two main lines. The first, with a theoretical
aim, consists in the development of mathematical tools to model the behaviour of
optoelectronic devices. The second will depend on the convenient equipment of our
Institute, which was planned when the Institute started its activities, but not
implemented at that time. Some previous links to other international institutions are
also foreseen, to fill some of our needs in the experimental area, namely in the
fabrication field.

Objectives
The objectives of the “Technology and Materials” group is to develop, process and
exploit new emerging materials such as special polymers and organic conductors and
semiconductors, and nanotechnologies, for the development of new devices and
systems in the broad field of telecommunications and related technologies.
In particular, during 2001, the following types of structures and devices have been
investigated:
i) Semiconducting and electroluminescent polymer films, for the fabrication and
characterization of electronic and opto-electronic devices and systems, such as LEDs
and LED active matrices, and FETs.
ii) Special polymer films, namely polymer gel electrolytes and polyimides for sensor
components. Polymer gel electrolytes were used as reference electrolytes in thin film
(solid state) reference electrodes for medical applications. Polyimide thin films were
used as humidity sensitive elements for integrated (on chip) microsensors.
63
iii) Crystalline organic conductors of the charge transfer salt and molecular type. The
research activity, in 2001, consisted on the characterization by Electron Spin
Resonance spectroscopy of new materials and study of the correlation between
molecular and crystalline structure and electrical and magnetic properties.

analog, mixed-mode and
digital circuits, with an emphasis on analog and mixed-mode circuits and systems.
Some short term objectives were the development of state-of-the-art, fast front ends,
optical communications being the main target application (with a side impact on front
ends for scientific instrumentation, mostly in Physics). Other areas of interest are the
development of current-mode circuits for analog applications. Another activity is
centered on interfaces for medium-access error-correcting and coding/decoding
applications.

Objectives
The Applied Mathematics Group has been involved in recent years in the following
three important fields of Mathematics: Optimization, Numerical Linear Algebra and
Partial Differential Equations. Apart from some more theoretical oriented studies, the
research of this group has been mainly focused in the design, convergence analyses,
implementation and testing of algorithms for the solution of many important problems
in these areas. The elements of the group have also been collaborating with
researchers of other areas in the design and solution of some models of engineering
and finance. This research will continue along the same lines in the next coming years.

Design and Optimization of Shielded Dielectric Horns
The theory of the dielectric cone antenna has been known since the early seventies.
On their own, this antenna has a reasonably circular symmetric radiation pattern but
exhibits an undesirably high side-lobe level. A properly designed metallic shield, which
does not interfere with the field structure of the dielectric cone, may be used to
reduce the side-lobe level. Although in principle this antenna should be quite
broadband, prototypes show that this is not the case. After proving that the metallic
shield performs as expected, aperture phase error and wave impedance mismatch at
the aperture were identified as the main disturbing factors. A lens placed at the
aperture corrects the phase error and a l/4 matching layer on the lens surface
improves aperture matching. The result is an antenna with an almost circular
symmetric radiation pattern, -27 dB side-lobe level and 4% bandwidth. (Carlos
Salema, Carlos A. Fernandes)
DSP-Based Winding Fault Diagnosis in
The major aim of this project basically comprises the development of a prototype, able
to provide a complete and reliable diagnosis of the operating condition of three-phase
power transformers, particularly regarding the occurrence of winding faults. For that
purpose, a modelling and simulation study was conducted, concerning either the
normal operation or the failure mode behaviour of three-phase power transformers, in
order to provide an evaluation of the suitability of diagnostic techniques, which can be
applied without taking transformers out of service and which can also provide a fault
severity criteria. The experimental validation work was also already performed. The
on-going activities, now under Phase II of the former Project, are mainly related to the
prototype assembly, external communications and laboratory and field tests. However,
due to a lack of funding during the last years the work is progressing slowly. (António

Global Monitoring Based on Smart Sensors for Environment Quality
This project was initiated on March 2001.The physical and biochemical parameters
that may express the water quality of Tejo estuary have been identified and classified
into two groups: 1) turbidity, ph, conductivity and salinity, temperature and salinity;
2) heavy metals (cadmium, mercury, lead and copper) and pesticides. Different
architectures of sensors for turbidity were theoretically and pratically studied
concerning its sensitivity and accuracy and different calibration procedures were
carried out. DAQ-PC and microcontroller based solutions were developed in order to
assure the control and acquisition of the sensors data (pH, turbidity or temperature) in
the calibration and the measurement phases. A practical approach of the optimal data
processing using intelligent structures such as neural networks (NN) was realised.
Referring to data sensor communication, different communication solutions (e.g.
Internet Data Socket Technology - RS232) were studied and implemented according
to environment assesment requirements (Helena Ramos, Pedro Girão, António Serra,
José Pereira, Octavian Postolache)

Mask Configurable Intelligent Power Integrated Circuits - Applications
A new methodology was developed which enables important improvements in Smart
Power designs using arrays based on a unique NMOS cell type in matrix arrangements
suitable to implement generic functions required by power management control
blocks. This design procedure enables low cost semicustom designs and new ICs
configuration strategies of easy industrial implementation towards Smart Power using
standard CMOS technologies. Cell libraries of programmable matrix arrangements
based on NMOS structures were developed to implement the required functions
towards power conversion and power amplification, by means of convenient metal
layers interconnection. Circuit topologies, that implement required functions, handling
high voltages, to control, drive, sense and protect devices, resorting, exclusively, to
NMOS structures were developed. Using new devices (GSLDD and GSLDSD),
previously studied and developed, breakdown voltage up to 50V, using a submicron
standard CMOS technology, were achieved. Basic blocks were characterised and
applications using these basic blocks were developed, such as: a Buck Converter 5/3.3V, 500mA; a class D Audio Amplifier - 1W @ 14V; a DC Motor Driver for speed
control @ 14 V; a DC-DC Boost converter 5/12V, with current control; and a Fuel
Electronic Injector @ 14V. An automatic bench was developed under this project to

Gels with innovative optical, magnetic and electrochemical properties
The main goal of the project is the study of relevant physical properties of new hybrid
xerogels (doped with lanthanide or ferromagnetic ions). Those sol-gel derived
materials, based on oxyethylene units grafted onto silica networks by urea and
urethane cross-links, are efficient white light emitters due to the convolution of a longlived emission originated in the NH groups of the urea or urethane bridges with
shorter-lived electron-hole recombinations occurring in the nanometer-sized siliceous
clusters. This feature will be exploited to obtain efficient white-light hybrids (L.

Statistical and Structural Learning: Applications in Multimedia Data Mining
and Retrieval
The main thread of this project is the development of new unsupervised learning
methodologies, using multimedia data mining and retrieval problems as an application
test bed. By unsupervised learning, one normally understands a set of techniques
which are able to identify intrinsic structure in data (e.g., clustering, density
estimation). More specifically, the following goals will be pursued: - New criteria for
unsupervised learning tasks, such as simultaneous feature and model selection; this is
particularly important in high dimensional spaces (typical of multimedia data), where
different feature sets will reveal different structure in the data. -Unsupervised learning
algorithms under a model-based framework and/or new cluster formation criteria;
refinement of existing techniques, broadening their range of applicability, namely
taking into account the specific nature of multimedia data (high volume, high
dimensions, hybrid representations). -New dissimilarity measures, adequate for
various types of representation typically found in multimedia data: strings/text,
quantitative (as in images and
sound), and hybrid. -Comparison and blending of
different clustering techniques and validation criteria into a workable methodology;
since no single method is the best on all problems, this is also a fundamental issue in
designing practically useful applications in a multimedia context.
-Efficient and
scalable learning algorithms able to handle large amounts of data in high dimensional
spaces. (Mário A. T. Figueiredo and Ana L. N. Fred).

Signal and Image Processing in Synthetic Aperture Sensing
This project addresses the following challenging research topics topics in synthetic
aperture
(SA)
imaging:
(1)
Moving
target
detection
and
estimation;
(2)
Interferometry; (3) Image restoration. (1) Moving target detection, estimation, and
imaging is important for wide area surveillance systems with limited revisit times. (2)
The problem of interferometry is essentially the estimation of absolute phase from a
pair (or more) SA images. Topographic maps are then obtained
with basis on the
estimated absolute phase images. (3) The pixel amplitude of SA images are, under
mild conditions,
a sample of a Rayleigh random variable. Therefore, the image
amplitudes corresponding to an homogeneous region exhibit random fluctuations,
termed "speckled noise". The following goals will be pursued, concerning each of the
three referred topics: (1)
Developing solutions to the so-called "blind angle
ambiguity" problem. It means that using just an antenna it is impossible to infer the
direction of the velocity vector. One way to remove the blind angle ambiguity is to
make simultaneous bistatic SA measurements with twodifferent antennas. Aiming at
the resolution of the blind angle ambiguity problem with only one antenna, it is
proposed the exploitation of recent results, derived by the proponents, on the
relations between the received signal and the moving target velocity. (2) Developing
Bayesian
approaches
to
the
absolute
phase
estimation
in
the
presence
of
discontinuities. The inclusion of discontinuities is relevant to obtain meaningful
estimates. On the other hand, most methods proposed in the open literature do not
take discontinuities into account.
(3) Developing Bayesian approaches to the
amplitude restoration that, as in item (2), take the amplitude discontinuity into
account. The Bayesian perspective,
based on the data generation model and on
existing "a priori" knowledge, is common to methodologies to follow in the items (1),
(2), and (3). In the case of interferometry and amplitude restoration, "compound
Markov random fields" are adopted as
"a priori" probability density function. This
model enforces smoothness on homogeneous regions and simultaneously preserves
discontinuities between neighbouring regions. (José M. B. Dias and Paulo C. Marques).

Channel Estimation Techniques in Mobile Communications
In all-digital receiver implementations, an oscillator with a good frequency stability but
not synchronized with the carrier, heterodynes the incoming signal to baseband (direct
conversion) where its quadrature components are digitized. In this type of receivers
carrier synchronization is replaced by channel estimation, which consists of the
following tasks: (i) estimation of the phase drift due to Doppler effect and/or
frequency poor alignement between oscillators. (ii) estimation of the channel timevarying gain provoked by fading and/or shadowing. The problem of channel estimation
presents new challenges with the emergence of mobile personal communications
based on, for example, non-geostationary satellites, which are affected by intense
Doppler frequency offsets. In these cases, the channel is strongly non-stationary
(even with very short time intervals), leading to the need to update phase and gain
estimates within the symbol interval. The methodology proposed in this project
reflects the previous team expertise in the area. The channel is modelled as a dynamic
system whose state is to be estimated. This approach has led to encouraging results;
they show the advantage of using nonlinear filters based on the representation of the
conditional probability density functions as an alternative to the extended KalmanBucy filter. Channel estimation in mobile digital communications is a relevant research
subject not only from the applications point of view but also by its theoretical and
conceptual aspects. This project proposes to resume previous work in this area by
focusing namely on the following aspects: a) synthesis of new algorithms for the
simultaneous joint channel and clock estimation, and symbol detection based on
stochastic nonlinear filtering; b)development of new open-loop frequency and
frequency-rate estimators; c) application of the above-mentioned algorithms in
scenarios of practical interest, such as the mobile digital communications with nonstationary orbit satellites; d) application to spread spectrum or multiple carrier
techniques where significant improvements are foreseen. (Fernando D. Nunes and

New measurement methods in Analog to Digital Converters testing
The influence of amplitude noise, phase noise and frequency errors in the sampling
clock and stimulus signal on the results of the histogram test of Analog to Digital
converters was studied. Based on this study, a methodology for the test parameters
design was established, in particular, the number of samples and records to be
acquired so that the results have the desired uncertainty and confidence level.A new
method for the static test of converters was developed. The new method differs from
the traditional histogram method in that is uses, as stimulus, a periodic signal with
small amplitude compared to the converter’s input range. These circumstance lead to
91
quasi static conditions for the test of converters. The offset of the stimulus signal is
varied in successive steps so as to stimulate the entire converter’s input range.The
proposed method replaces with advantage in terms of speed and cost of equipment,
the static test traditionally used in these cases. Frequency-domain (FFT single tone
and dual tone) ADC testing, together with time-domain analysis was be used to obtain
the transfer characteristic of converters, including those who show histeresys (António

Statistical Characterization of Telecommunications Traffic - SCALE
This project aims at the statistical characterisation of actual traffic in broadband
networks. This research is justified because most of the existing reports in the
literature are based on a few number of somehow outdated traffic traces (the Bellcore
traces, 1989, 90 and 92). In the project intensive traffic measurements will be made.
The measurements will be representative of the most important services and will
include Internet Access, LAN-to-LAN Interconnection, Video Distribution and MPEG4
based Multimedia Retrieval. In the literature several classes of theoretical models have
been proposed that may be applied to describe telecommunications traffic: renewal,
Markov based, Fluid, Autoregressive, Transform-Expand-Sample (TES) and SelfSimilar. A careful selection of traffic models has been done for the measured traffic
data sets based on existing literature and on the measured data characteristics.
Following the initial selection of traffic models, suitable parameter estimation
procedures have been implemented and used on the measured data. Since the ability
of a model to predict network performance is a measure of its quality, forecasts of the
most important network parameters are being compared with measured values for
each adjusted model. The final selection of a model for a particular set of data will be
based on the prediction quality of the performance parameters and the diagnostic
analysis results of the individual models. It is a joint project with the IT – Lisbon Pole,
IT – Aveiro Pole, Dept. Mathematics of IST and Dept. Mathematics of University of
Aveiro. (Carlos Belo, Rui Valadas, António Nogueira, Paulo Salvador, Daniel Zaragoza).

The project ended in December 2001. The project aimed at the establishment of
research, development and teaching capacities in the domain of virtual measuring
systems at the CEI (Maputo - R. MozambiqueI). In 2001, conferences on Quality, on
Accreditation of calibration and test laboratories and on Electromagnetic Compatibility
a seminar on Control and transmission of data in measuring systems using protocols
RS 232 and IEEE 488, and a course on Data Aquisition and LabView were organized
and lectured by Helena Ramos and Pedro Silva Girão at the FE/UEM (Maputo - R.
Mozambique) in October/November. Several virtual systems were developed for the
caracterization of electronic devices such as analog filters, diodes and operational
93
amplifiers. The use of the internet to control tests or to publish results was
implemented (Helena Ramos, Pedro Silva Girão, António Serra, Augusto Nunes Junior,
Lourino Chemane).

In the ATLAS project fibre-optic WDM transmission over 500-1,000 km with an
aggregate capacity around 1 Tbit/s is investigated by adopting return-to-zero signal
format and the dispersion management technique, without resorting to intermediate
regeneration. Different network architectures using All Optical Wavelength Converters
(AOWC) are currently under investigation. This project wants to assess the problems
encountered when high capacity fibre transmission is associated with an intermediate

Transport Protocol and Resource Management for Mobile Satellite Networks
In this project is developed a transport architecture for reliable end-to-end transfer in
satellite networks, as an alternative for overcoming the poor utilisation of satellite
links that TCP affords in such environments. The approach followed exploits the ideas
of supporting the end-to-end concatenation of arbitrary transport protocols, and of
providing and exploiting mechanisms for applications exchange information with a
satellite resource manager about their resource requirements. The scope of the
project comprises the development and validation of a transport and resource
management architecture and of a transport protocol adapted to the satellite link
environment, and the implementation and test of a prototype. (José M. Brázio, Daniel

GRIP
The GRIP project investigates the most recent models, architectures and software
techniques to be applied to network and service management of IP networks. The
project built two different management systems following two different software
approaches. The first one, is based on a flexible and modular architecture which uses
several layers of APIs in order to achieve vendor independence and openeness to third
party management application developement. This management system allows the
98
configuration and monitoring of QoS parameters over an IP DiffServ network. The
emergent Mobile Agent Technology has been considered a good support for
developing. Therefore, the components of this system have been built in JAVA and run
over the Grasshopper mobile agent platform. A user-friendly management application
is also provided in order to make easy the configuration and monitoring of the IP
DiffServ routers. A demonstrator based on Linux routers has been set-up for testing
the management capabilities of this platform. The second management system covers
the definition and implementation of a system for the integrated management of IP
over WDM networks, in an effective and flexible way. As a result, the project has
defined a complete management architecture and has implemented some system
components, related to the IP-NMS and Integrated NMS. In addition this project setup

Study of the Impact
of Wind Turbine Power Generators on Radio Telecommunication Services
Wind turbines may be a source of disturbance in the radiation fields of TV broadcast
transmitters. The situation is particularly serious when the direct path from the
transmitter to the receiver antenna is obstructed while both transmitter and receiver
antennas have an unblocked path to the wind turbine. Starting from an analysis of the
diffracted field by the pylon we proceed to implement a simple rule derived from ITU
Recommendation 805 to define a minimum clearance distance from an isolated wind
turbine and a TV transmitter antenna. Measurements using a scaled model confirm the
existence of the floor level in the scatter model used in ITU Recommendation BT.805.

Stable routing policies for the Internet
Contrarily to the usual, shortest-path routing, the inter-domain routing in the Internet
is based on local route choice policies. These policies are mostly dictated by the
commercial relationships established between domains. This approach to routing,
materialised currently in the BGP protocol, raises a large number of both practical and
fundamental questions, now under intense scrutiny by both operators and academic
researchers. The work which has been developed in this topic consists of identifying
104
conditions for the local path choice policies to be globally stable. For this purpose, a
simplified model of BGP has been analysed, using distributed algorithms concepts and
formalism. (João Luís Sobrinho).

This project is intended to explore adequate strategies for diagnosing the occurrence

include the diagnostic routines into the control module, therefore allowing for the
introduction of remedial control strategies soon after failure occurrence and thereby
improving reliability and maintainability. In other words it is envisaged the
development of fault tolerant telecommunications energy systems. Outside of the
large switching centers, the switched mode rectifier/charger rules, since it is ideally
suited for the low power requirements and the potentially harsher environment. In
almost all of these type of systems the location is unmanned; so reliability, fault
tolerance, repairability and monitoring are important. For that purposes, a modelling
and simulation study was conducted, concerning the normal operation of switched
mode power supplies. The failure mode behaviour is now being investigated in order
to allow for the evaluation of the fault tolerant strategies that can be adopted against
a complete system failure. (António João Marques Cardoso, Acácio Manuel Raposo

Traffic and Congestion Control in Multimedia Networks
The role of traffic control in current networks is growing due to the need for providing
different quality of service to multimedia applications. From the network point of view,
congestion avoidance is an important mechanism that needs to be implemented to
prevent the collapse of the infrastructure. From the applications point of view, the
generated traffic, to be carried by the network, can be shaped to cope with network
conditions while keeping acceptable quality at the end user. The congestion status has
to be computed by the routers at the core of the network and the information
transmitted to the end users. Within this project a stateless algorithm for the core
routers has been proposed and analysed. It was shown by simulations that even if the
congestion information is reduced to one bit per packet sources can adapt to changing
network conditions avoiding overload. Also, the system that consists of the adaptation
algorithm at the sources and the proposed algorithm at the bottleneck routers has
been shown to be stable for practical network configurations. The research work within
this project is directly connected to post-graduate studies (1PhD). (Carlos Belo,
