Adaptive Cross-Layer Strategies for Fourth Generation Wireless Communications
Ubiquitous support of heterogeneous services with prescribed QoS requirements is an ever-increasing demand in the fourth generation of wireless communication systems. Unpredictable and variable nature of environment and scarcity of resources necessitate exploiting efficient adaptive resource allocation strategies in operating the emerging networks. Recent growth in popularity of high-data rate applications and the need for larger bandwidths for transmission of multimedia content have also made the ideas of ?Resource sharing? and ?Cognitive radio? very attractive.
