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.
