Impulse Radio Ultra Wide Band Based Mobile Adhoc Network Routing Performance Analysis

This study presents with the routing overhead analysis of impulse radio - Ultra Wide Band based wireless networks which Employs Dynamic Nature Routing (EDNR) method for determining and selecting the stable route in Mobile Adhoc Network (MANET). This method requires only two sample packets and uses piggyback information on Route-Request (RREQ) and Route-Reply (RREP) packets during a route-discovery procedure. Conventional ENDR results in better routing overhead and packet delivery ratio characteristics with higher energy consumption. The proposed method explores the characteristics of UWB nature of routing based on Node lifetime and Link lifetime prediction for reducing the required bandwidth while maintaining higher packet delivery and lower routing overhead. Simulation results illustrate the improvement of packet delivery ratio by 5% and reduction of routing overhead by 4.8% of the proposed UWB EDNR method over the conventional EDNR method. For higher packet delivery ratio and reduced routing overhead with efficient bandwidth utilization can be achieved by applying UWB based EDNR routing that is desired for real time data communications.
