Enhanced Energy Efficient Routing Protocol (EEERP) for lifespan optimization in WSNs

Wireless Sensor networks are the low powered networks formed by sensor nodes that are used extensively in various fields. As a result, improving the network lifetime is the most important task to be accomplished. Since the sensor nodes are low battery powered, the conservative routing protocols cannot be applied. The recent studies have proved that clustering can remarkably reduce energy consumption thereby extending the lifetime of WSN. In this paper, we propose Enhanced Energy Efficient Routing Protocol (EEERP) for improving life of the network where clusters are formed during setup phase of the network. A sensor node remains in the same cluster throughout the lifespan of the network. The proposed protocol also shows a significant decrease in the energy dissipation and a noticeable throughput.
