Energy Aware Routing Protocol for Low Energy Sensor Networks

In this paper, we propose an energy efficient data forwarding protocol called Energy Aware Geographic Routing Protocol (EAGRP) for wireless sensor networks to extend the life time of the network. In EAGRP, both position information and energy are available at nodes used to route packets from sources to destination. The routing design of EAGRP is based on two parameters: location and energy levels of nodes. Each node knows the location and energy level of its neighbors. The performance measures have been analyzed with variable number of nodes. The simulations were carried out for different number of nodes. The proposed protocol was compared with Greedy Perimeter Stateless Routing (GPSR). Simulation results show that EAGRP performs competitively against the (GPSR) in terms of packet delivery ratio, throughput, energy consumption, and delay. Consequently, it can be concluded that EGARP does efficiently and effectively extend the network lifetime by increasing the successful data delivery rate.
