This paper presents a novel multipath energy aware routing for wireless ad hoc network. A deep analysis of different routing metrics such as MBCR, MMBCR and MDR have been led out and the Minimum Drain Rate metric has been selected as energy metric to integrate in the Multipath DSR protocol. Performance comparison with an energy efficient DSR (DSR-MDR) has been presented showing the benefits of the multiple route selection. An update mechanism and a simple data packet scheduling among the energy efficient paths have also been implemented to update the source route cache and for improving the traffic and energy load balancing. Comparison of Multipath DSR with MDR, cache update and round robin scheduling (MEA-DSR) has been also compared with Multipath DSR with MDR metric without cache update mechanism (MDSR-MDR). Simulation results confirm the improvements associated to multipath extension with energy aware metric with respect to the MDR-DSR (unipath routing).
In REF , the authors propose the Multipath Energy Aware DSR (MEA-DSR).
