Location Aided Energy Efficient Routing Protocol in Wireless Sensor Network

In this paper, a Location Aided Energy Efficient Routing (LAEER) protocol is proposed. The proposed on-demand routing protocol consider location and residual energy of the nodes as the routing metric. Only the forwarding neighboring nodes are involved in routing while the non-forwarding nodes are switched to idle state. This ensures reduction in energy consumption in the network. The novelty of the proposed work is that the best progress node with acceptable link quality is alone chosen as the optimal forwarding neighbor. This leads to reduction in memory and bandwidth utilization. The performance of the proposed LAEER protocol is compared with AODV. From the simulation results, it is found that the proposed LAEER protocol outperforms AODV in terms of control overhead, average end-to-end delay, packet delivery ratio and average energy consumption in the network.
