Energy consumption is a major concern in most of the present day devices in wireless networks. Especially in Ad hoc networks, energy is a limited factor. Random movement in nodes add to the frequent failure of routes which adds to the energy consumption in the network. In this paper, a routing protocol is proposed which is based on a modification of the conventional DSR (Dynamic Source routing). A comparative analysis is performed with respect to energy consumption, maximum throughput and delay. The routing protocols used for reference in this analysis are DSDV, AODV and conventional DSR. Experimental results show that the proposed modified DSR shows a reduced energy consumption, improved rate of maximum throughput and a reduced delay compared to above mentioned routing protocols.
