A Comparative Analysis MAC Protocols for Optimization of UWB Channels in the Presence of Fast Fading & Shadowing

Y. V. AdiSatyanarayana, K. Padma Raju, P. V. Naganjaneyulu

Abstract: In the existence of UWB channels that provide large bandwidth and potential promise for high quality services and applications in wireless networks MAC protocol acting a crucial role in utilizing the channels efficiently. Recently Cai et al. explored the view of Exclusive region for building Distributed Exclusive Region (DEX) Based MAC Protocol. DEX MAC improved performance of wireless network for using UWB channels effectively in distributed and asynchronous fashion. Their protocol was not evaluated in the presence of fast fading and shadowing conditions of UWB channels, these can be evaluated in the presence of fast fading and shadowing conditions of UWB channels previous article. In this we compare different DEX MAC protocols by using different parameters like PDR, Delay, throughput, overhead, energy consumption, packet drop. With mathematical analysis. The simulation results give better performance with existing one.

Keywords: fast fading, shadowing, DEX MAC, UWB
