Preface
Mobile and wireless communications are moving towards a new era that will be
characterized by the seamless collaboration of heterogeneous systems, the need for
high speed communications while on the move and for advanced services with qual-
ity guarantees. Recent market research studies show that most of the traffic in the
future wireless networks will be produced by mobile multimedia services which are
expected to proliferate by the year 2010. On the other hand mobile and wireless
communications technology is becoming more and more important in developing
countries where people demand fast deployment and low cost for broadband wire-
less internet services.
The objective of this volume is to gather research and development on topics
shaping the fourth generation (4G) in mobile and wireless communications and
reveal the key trends and enabling technologies for 4G. We envisage 4G wireless
communication systems as IP based solution providing integrated services (voice,
data, multimedia) regardless of time and end-users’ location. 4G technologies will
manifest the benefits of the wireless and wired technologies convergence, through
enabling a wide range of innovative (both indoor and outdoor) applications. 4G
applications will feature premium quality, high security and an affordable cost. The
vision, though fantastic, is associated with a host of technical and technological
challenges. A great deal of the later are discussed in the articles of this volume, which
aims at providing insights on the research issues and solutions that are directly asso-
ciated with leading edge 4G technologies and services. Taking into account recent
developments in the world of wireless communications we have given emphasis to
cover all these technologies and aspects that are considered as cornerstones for
achieving the goals set for 4G and that will further boost research and development
of next-generation mobile communications.

About the Editors
Dr.-Ing. Sofoklis Kyriazakos was born in 1975 in Athens. He graduated Athens
College 1993 and studied Electrical Engineering and Telecommunications in RWTH
Aachen, Germany. Then he moved to the National Technical University of Athens,
where he obtained his Ph.D. in Telecommunications in 2003. He also received an
MBA degree in Techno-economic systems from the same university. He has more
than 60 publications in international conferences, journals, books and standardiza-
tion bodies. He has been invited as reviewer, chairman, member of the committee,
panelist and speaker in many conferences and he has served as TPC chair in 2
International conferences. Currently he holds the academic position of Assistant
Professor in the University of Aalborg.
Sofoklis has managed, both as technical manager and coordinator, a large
number of multi-million Telecom and IT projects in NTUA. During the last seven
years he also worked as external consultant in the area of Telecommunications. In
2006 he founded Converge S. A., an ICT company that is member of the PRC Group,
that he is now the Managing Director.
Prof. John Soldatos PhD (born in Athens. Greece in 1973) obtained his
,
Bachelor/MSc degree in 1996 and his Phd in 2000, both from the ECE Depart-
ment of the National Technical University of Athens (NTUA). Dr. Soldatos has
had an active role (wp-leader, technical manager, project manager) in more than
20 European Commission co-funded research projects. He has also considerable
experience (senior developer, IT systems architect, team leader, technical project
manager) in several enterprise projects, where he worked for many leading Greek
enterprises. Furthermore, he has been involved in several large scale industry projects
as a principal IT consultant. As a result of his research activities he has co-authored
more than 110 papers published in international journals and conference proceed-
ings, while he has co-edited two books and two journal special issues. His cur-
rent research interests are in Pervasive, Grid and Autonomic Computing, as well
as Broadband Networking. Dr. Soldatos has attracted (as principal investigator)
multi-million euro research grants in all these areas. He also serves as a reviewer
in major journals, as an evaluator for EU projects/proposals and business plans,
while he has also served as organizing chair, tutorial chair, and TPC member in
numerous conferences. Recently, he served as TPC co-chair of the IEEE PIMRC07
conference. Dr. Soldatos is with Athens Information Technology ( AIT) since March
2003, where he is currently an Associate Professor.
Prof. George T. Karetsos was born in Karditsa, Greece in 1968. He received
his diploma in electrical and computer engineering in 1992 and his Ph.D. in
