Enhanced Distributed Exclusive Region Based MAC Protocol for UWB Channels with Fast Fading and Shadowing

Abstract: In the presence of UWB channels that provide large bandwidth and potential possibilities for high quality services and applications in wireless networks MAC protocol plays a vital role in utilizing the channels effectively. Recently, Cai explored the notion 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. However, their protocol was not evaluated in the presence of fast fading and shadowing conditions of UWB channels. In this study, we design EDEX (Enhanced DEX) based MAC which has contingency measures in the presence of such conditions. The EDEX thus works for dense network with high data rate requirements. We implemented EDEXMAC using NS2. The simulation results are compared with other existing DEX based MAC protocols.
