Energy Aware Multipath Routing Scheme for Wireless Sensor Networks

Sensor nodes are deployed in remote wireless sensor networks (WSNs) which are mainly constricted by battery life and communication range. Single path routing mechanisms in WSNs leads to drastic power utilization and path failure. A multipath routing scheme using cooperative neighboring node concept is presented in this paper. Based on the availability of the energy at the neighboring nodes, multipath routes are recognized. Our simulation results demonstrate that the proposed scheme enhances the performance in terms of multipath identification delay, end-to-end delay, packet delivery ratio and network life time etc.
