The efficient node-energy utilization in wireless sensor networks has been studied because sensor nodes operate with limited power based on battery. To extend the lifetime of the wireless sensor networks, maintaining balanced power consumption between sensor nodes is more important than reducing total energy consumption of the overall network. Since a large number of sensor nodes are densely deployed and collect data by cooperation in wireless sensor network, keeping more sensor nodes alive as possible is important to extend the lifetime of the sensor network. In this paper, we submit an efficient energy aware routing protocol based on AODV ad hoc routing protocol for wireless sensor networks to increase its lifetime without degrading network performance. The proposed protocol is designed to avoid traffic congestion on minor specific nodes at data transfer and to make the node power consumption be widely distributed to increase the lifetime of the network. The performance of the proposed protocol has been examined and evaluated with the NS-2 simulator in terms of network lifetime and end-to-end delay. |
