ABSTRACT
This chapter highlights the use of cross-layer design for a few selected scenarios including wireless local area networks (WLAN) and cellular transmissions. It provides some insight into the challenges faced by a cross-layer design approach. The chapter presents a brief tutorial of the applications of cross-layer design for wireless applications. It discusses the benefits of the cross-layer approach for multimedia transmission over WLANs. The chapter explains some of the integrated cross-layer frameworks in the Third Generation Partnership Project Long-Term Evolution standard and also applications of cross-layer design in future wireless networks focusing on energy enhancements and cognitive radio. It also discusses some of the challenges faced by a cross-layer approach focusing on the some of the system design aspects. The chapter summarizes some of the essential concepts. It shows that possible benefits of some of the proposed architecture with examples from WLAN, cellular and also future wireless networks including cognitive radios.
