Wireless sensor networks consist of small battery powered devices with limited energy resources. Once deployed, the small sensor nodes are usually inaccessible to the user, and thus replacement of the energy source is not feasible. Hence, Self Healing is a key design issue that needs to be done in order to improve the life time of the network. Several network layer protocols have been proposed to improve the effective lifetime of a network with a limited energy supply. In this article we propose a Self Healing Routing Protocol which efficiently utilizes the energy availability of the nodes to identify the best possible route to the destination so that the network can be healed from failure. Simulation results show that the Self Healing routing scheme achieves much higher performance than the classical routing protocols, even in the presence of high node density.
