Product Description
Satellite communication systems represent an important solution to integrate and to complement terrestrial systems, since satellites allow the following advantages: easy fruition of both broadcast and multicast high bit-rate multimedia services; provision of backup communication services for users on a global scale; efficient support of high-mobility cellular users (e.g., users on trains, planes, etc.); and support of broadband applications and services in rural and remote areas for both fixed and mobile users.
Multimedia traffic support, multicast and broadcast services are the driving forces for new satellite systems that are expected to provide services with comparable Quality of Service (QoS) levels of terrestrial systems. In particular, the interest is here on the Satellite UMTS system for mobile users and the DVB-S/DVB-S2/DVB-RCS networks for broadband fixed users.
New satellite network architectures, protocol design, and adaptivity schemes are necessary to allow the support of prospected future services. Satellite resources are costly and satellite communications impose special constraints with respect to terrestrial systems in terms of channel model, attenuation, propagation delays, fading, etc. The ISO/OSI reference standard is based on a layering paradigm, a strict modularity and layer independence.
Such classical approach may lead to non-optimal performance in IP-based next-generation satellite communication systems. In this framework, an optimized cross-layer approach is needed where interactions even between non-adjacent protocol layers are employed. This book provides significant knowledge on innovative radio resource management schemes for satellite communication systems that exploit lower layer adaptivity and the knowledge of layer 3 IP QoS support and transport layer behavior.
This book is an interesting novelty since it integrates competencies considering all the parts of system design (i.e., propagation aspects, radio resource management, access protocols, network protocols, transport layer protocols, etc.) to cover both broadband and mobile satellite systems. A detailed analysis of cross-layer air interface design will be provided with new simulation results, proving that such approach can permit to guarantee high QoS levels for differentiated traffic classes and high utilization of air interface resources.
Two scenarios will be addressed for cross-layer optimization issues, that is the satellite version of the terrestrial UMTS for mobile users (3GPP) and the DVB-S/-S2/-RCS air interface for broadband fixed transmissions (ETSI). This book is intended as the outcome of the research results obtained during the last two years in the workpackage 2430 (SatNEx project, leaded by Dr. Giovanni Giambene - University of Sienna, Italy.
About the Author
Giovanni Giambene received the Dr. Ing. degree in Electronics from the University of Florence, Italy, in 1993 and the Ph.D. degree in Telecommunications and Informatics from the University of Florence, Italy, in 1997. From 1994 to 1997, he was with the Electronic Engineering Department of the University of Florence, Italy.
He was Technical External Secretary of the European Community Project COST 227 Integrated Space/Terrestrial Mobile Networks. He also contributed to the Resource Management activity of the Working Group 3000 within the RACE Project called Satellite Integration in the Future Mobile Network (SAINT, RACE 2117).
From 1997 to 1998, he was with OTE of the Marconi Group, Florence, Italy, where he was involved in a GSM development program. In the same period he also contributed to the COST 252 Project (Evolution of Satellite Personal Communications from Second to Future Generation Systems) research activities by studying the performance of PRMA protocols suitable for supporting voice and data transmissions in low earth orbit mobile satellite systems.
In 1999 he joined the Information Engineering Department of the University of Siena first as research associate and then as assistant professor. He has contributed to the activities of the Personalised Access to Local Information and services for tOurists (PALIO) IST Project within the fifth Research Framework of the European Commission.
Dr. Giovanni Giambene has co-authored a book published by Kluwer Academic Publishers, Boston, with the title "Protocols for High-Efficiency Wireless Networks" (November 2002). Giovanni Giambene is author of the recently published book (June 2005) by Springer, entitled "Queuing theory and Telecommunications: Networks and Applications".
Recently he has been the General Chair of the IEEE ComSoc-supported event entitled: 2nd International Symposium on Wireless Communications Systems (ISWCS 2005), held in Siena, Italy, September 5-9, 2005. At present he is involved in the SatNEx network of excellence (FP6 programme) in the satellite field as responsible of the work package dealing with OSI layer 2 protocols (WP2430).
Dr. Giambene is a reviewer of the following journals: IEEE Transactions on Vehicular Technology, IEEE Transactions on Wireless Communications, IEEE Transactions on Networking I and IEE Electronics Letters. Dr. Giambene is member of IEEE, IEICE and the IEEE Communications Society "Satellite and Space Communications Technical Committee".
