Preface
This book contains the refereed proceedings of the 3rd International IFIP-TC6
Networking Conference, Networking 2004. Conferences in the Networking series
span the interests of several distinct, but related, TC6 working groups, including
WorkingGroups 6.2, 6.3, and 6.8. Reflecting this, the conference was structured
with three Special Tracks: (i) Networking Technologies, Services, and Protocols;
(ii) Performance of Computer and Communication Networks; and (iii) Mobile
and Wireless Communications.
However, beyond providing a forum for the presentation of high-quality re-
search in various complementary aspects of networking, the conference was also
targeted to contributing to a unified view of the field and to fostering the interac-
tion and exchange of fruitful ideas between the various related (and overlapping)
specialized subcommunities therein. Towards this second objective, more than
a few conference sessions (and thematic sections in this book) ‘cut across’ the
Special Tracks, along more generic or fundamental concepts.
Networking 2004 was fortunate to attract very high interest among the com-
munity, and the conference received 539 submissions from 44 countries in all
five continents. These figures correspond to a remarkable increase in submis-
sions from the previous very successful events (roughly, a 156% increase over
Networking 2000 and 71% over Networking 2002), and indicate that Networ-
king conferences are progressively becoming established as worldwide reference
events in the field.
The high number of submissions provided an excellent opportunity for a
high-quality program but also called for a very demanding and laborious pa-
per evaluation process. The 99 members of the Technical Program Committee,
together with more than 750 additional experts engaged as external reviewers,
worked efficientlyand responsibly undertighttime constraints to produce a total
of some 1600 reviews, towards responding to the authors with insightful, detailed
feedback and providing the basis for the final paper selection.
As a result of this process, 103 papers were finally selected from the 539 sub-
missions (at an acceptance rate below 20%) for presentation during the con-
ference’s technical sessions. Additionally, to allow the conference participants
to benefit from further worthwhile and stimulating research results, 40 papers
were accepted for presentation in a poster session; these papers appear in the
proceedings in short form. Overall, the final program was excellent and diverse,
and covered both fundamental issues in networking as well as emerging topics.
It should be noted that, given the many submissions and the tight constraints,
many good papers could not be accommodated.
The main program of Networking 2004 covered three days and included stre-
ams of up to three parallel sessions, plus a poster session for the presentation
of the short papers. In addition to these components, the program was enriched
by three stimulating invited talks offered by world-renowned researchers in the

field, specifically: Jim Roberts on “From ATM to IP and back again: the la-
bel switched path to the converged Internet, or another blind alley?”, Leandros
Tassiulas on “Cross-layer design issues for quality of service provisioning in wi-
reless networks”, and Ian Akyildiz on “Research challenges in wireless sensor
and actuator networks”. The main conference program was complemented by a
diverse set of high-quality tutorials and workshops.
The final result wouldn’t have been possible without the dedication and hard
work of many colleagues. Special thanks are due to the members of the Technical
Program Committee and to all external referees for their invaluablehelp with the
paper reviews and their overall sense of responsibility and responsiveness under
very tight deadlines in a particularly busy period. Another word of thanks goes
to the Webmaster Manolis Solidakis and to the General Chair Nikolas Mitrou,
who worked hard to ensure that flexible and effective technical support was
available during the paper evaluation and the final paper selection. Finally, we
are grateful to all authors who honored Networking 2004 by trusting their work
to the conference.

Message from the General Chair
No doubt the world economy is being globalized at a rapid pace, while, at the
same time, it is becoming more and more information intensive. The joint evolu-
tion and convergence of these fundamental trends towards the global, knowledge-
based society leans upon a bold scientific and technological objective: pervasive
information processing and ubiquitous networking. Clearly, technological advan-
ces in all aspects of networking are central to this objective.
In such a context, Networking 2004 strove for a distinct and valuable con-
tribution to the field. Organized jointly by the Institute of Communication and
Computer Systems of the National Technical University of Athens and the Insti-
tute of Informatics and Telecommunications of the NCSR (National Centre for
Scientific Research) “Demokritos”, it was the third event in a series of IFIP-TC6
networking conferences, launched in 2000 and organized every 2 years thereafter.
In common with its predecessors, Networking 2004 aimed at reviewing progress,
presenting recent advances, identifying trends and refreshing vision in this hot
field, by bringing together active and proficient members of the networking com-
munity from both academia and industry. It covered all aspects of networking,
focusing especially on three main areas (Special Tracks): (a) networking techno-
logies, services, and protocols, (b) performance of computer and communication
networks, and (c) mobile and wireless communications. The conference lasted
six days and included the main program (three days), tutorials (one and a half
days) and thematic workshops attached to the main event (one day).
The organization of such an ambitious event required a considerable effort
and commitment by very many people. I therefore wish to express my deep
appreciation to all of the Executive Committee members for their outstanding
work.
The heart of the conference was, of course, its main program. The dramatic
increase in the number of submitted papers (more than 70%, compared to the
previous event in 2002) clearly indicates the increasinginterest of the community
in our IFIP-TC6 networking conferences. Diligence in the reviewing and selec-
tion process was necessary, in order to thoroughly handle such a large number
of submissions and, hopefully, to hand over to the next organization a confe-
rence standard even higher than that inherited. A special appreciation is due
to the Technical Program Chair, Kimon Kontovasilis, for his deep devotion to
this extremely delicate and demanding task. Sincere thanks are addressed also
to the three Special Track Chairs, George Rouskas, Ilias Iliadis and Lazaros Me-
rakos, who worked diligently towards a high-level conference program. The TPC
members, as well as more than 750 additional external experts/referees, are also
warmly thanked for their excellent work.
Within the main program, keynote speeches are “tracer bullets” in the un-
exploited sky of new trends and ideas, or critical retrospections on fundamental
aspects of networking. Here I have to thank the Invited Speaker Co-chairs Leo-
VIII Message from the General Chair
nidas Georgiadis and Michael Paterakis and, of course, our distinguished invited
speakers.
The tutorial program enriched the main conference program with thorough
half-day presentations, covering theoretical and practical aspects of recent ad-
vances in networking. The tutorials were mainly targeted to young researchers
and practitioners in the field who wish to foster their skills and background
knowledge. Many thanks to the Tutorial Co-chairs Christos Douligeris, Gunnar
Karlsson and Dimitris Pendarakis for organizing an interesting set of tutorials.
The last day of the conference was devoted to thematic workshops focusing on
areas of special interest or of remarkable evolution dynamics. Four such works-
hops were scheduled: Next Generation Networking Middleware (NGNM04, orga-
nized by Nikos Anerousis and George Kormentzas), Data Processing and Storage
Networking: Towards Grid Computing (DPSN04, organized by Fotini-Niovi Pa-
vlidou, John Soldatos and Evangelos Vayias), Streaming Media Distribution over
the Internet (SMDI04, organized by Charalampos Patrikakis, Marco Combetto
and Constantinos Boukouvalas) and Wireless Internet and Reconfigurability (4th
ANWIRE, organized by Nikos Passas). The workshop chairs did an excellent job
to achieve quality workshops, commensurate with the high level of the rest of
the conference.
Our Web engineer, Manolis Solidakis, did his best to provide user-friendly
on-line facilities during all preparatory phases: paper submission and review,
registration, program dissemination. I thank him for his commitment to that.
Jointly with the Technical Program Chair, we would like to address our
final word of thanks to the administration of the organizing institutes within
NTUA and NCSR “Demokritos” for their support, as well as to the IFIP-TC6
management, who entrusted us with the conduct of this important event.
Not too long ago, we received the staggering news that Olga Casals, our
good friend and colleague, an active researcher and TPC member of previous
Networking conferences (intended as a TPC member of this conference too)
suddenly passed away. The Best Paper Award of Networking 2004, presented to
its recipient on the last day of the conference, was devoted to her memory.
