Klappentext Providing quality of service for 3G networks - where image and video content is quickly and easily downloaded to a mobile wireless device- is a major challenge for network operators. Cross-layer resource allocation offers a new means to develop quality of service by improving signal quality over a larger area! increasing network and spectrum utilization (thereby freeing up usable bandwidth and capacity) and by increasing multimedia applications throughput by up to nine times. All this means a better user experience for the customer! providing faster browsing! shorter buffering times for multimedia and fewer interruptions. As a result of the potential benefits! research activity in both Universities (globally) and industry on cross-layer design and optimisation issues is very strong. This book is the first to link together the physical and network layers by providing cross-layer resource allocation techniques! models and methodologies for developing better 3G networks. This is an ideal reference on cross-layer resource allocation between the PHY and MAC layers for R&D and network design engineers and researchers in universities. Zusammenfassung Resource allocation in wireless networks is traditionally approached either through information theory or communications networks. This title covers such topics as different views of spectral efficiency! the role of spatial diversity! of delay in resource allocation! and possible extensions to OFDMA systems.

Report
"This is a nice treatise on the cross-layer optimization of wireless systems. The authors offer a useful guide on a timely subject most relevant to future generation of wireless communications." --Lang Tong, Irwin and Joan Jacobs Professor in Engineering, School of Electrical and Computer Engineering, Cornell University, USA"The authors have written a book that offers to researchers and practitioners a thorough and comprehensive overview, with a cross-layer perspective, of theory, models and methods related to resource allocation in multi-user wireless systems." --Professor Velio Tralli, University of Ferrara Communication Technologies Laboratory
