Cross-Layer Resource Allocation in Wireless Communications

TRAMA

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.

NOTE EDITORE

Cross-Layer Resource Allocation in Wireless Communications offers practical techniques and models for the design and optimisation of cross-layer resource allocation - one of the hottest topics in wireless communications. Resource allocation in wireless networks is traditionally approached either through information theory or communications networks. To break down the barriers between these distinct approaches, this book bridges the physical and network layers by providing cross-layer resource allocation techniques, models, and methodologies. Its unique approach allows optimisation of network resources and will enable engineers to improve signal quality, enhance network and spectrum utilization, increase throughput, and solve the problem of shadowing. Topics covered include different views of spectral efficiency, the role of spatial diversity, of delay in resource allocation, and possible extensions to OFDMA systems. This will be 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 dealing with sensor networks and cognitive systems.
