Power aware and topology aware ad-hoc on-demand multipath distance vector routing for MANET

Abstract

Our earlier work [1] [2] shows interesting characteristics of transmission range/power of the MANET nodes on the performance of multipath MANET routing protocol. The objective of this work is to improve the performance of a MANET multi-path routing protocol without increasing or decreasing its default transmission range of the nodes. The proposed work is to control the routing process and only allow hops with maximum possible distances in a route based on the received signal strength at each node. We propose topology aware and power aware ad hoc on-demand multipath distance vector routing protocol based on the maximum transmission range. We call this model as AOMDV_RR Range Routing and implemented it under ns2 by improving the standard AOMDV protocol. We studied the proposed AOMDV_RR and the standard AOMDV under different network densities and measured the performance for suitable metrics. Measurable difference in performance was realized and the proposed AOMDV_RR performed better than normal AOMDV with respect to metrics network overhead, throughput and energy consumption.
