Abstract

As we are aware the there is limited rechargeable power in the sensor nodes we must design the routing protocol in such a way that we can obtain optimum energy saving. Henceforth we are focusing here on the minimization of the energy utilization in the wireless sensor networks and also increasing the network lifetime. Here we follow the principle of opportunistic routing wherein we consider that the multihop relay decision is made based on the comparison of energy of the sensor nodes and also the distance to the sink. Specifically, an Energy Saving via Opportunistic Routing (ENS_OR) algorithm is designed to provide minimum power cost during transmission and also providing protection to those nodes having low residual energy, therefore improving the network performance.
