摘要：The efficient node-energy utilization in wireless sensor networks has been studied because sensor nodes operate with limited battery power. To extend the lifetime of the wireless sensor networks, we reduced the node energy consumption of the overall network while maintaining all sensors balanced node power use. Since a large number of sensor nodes are densely deployed and interoperated in wireless sensor network, the lifetime extension of a sensor network is maintained by keeping many sensor nodes alive. In this paper, we submit power aware routing protocol for wireless sensor networks to increase its lifetime without degrading network performance. The proposed protocol is designed to avoid traffic congestion on specific nodes at data transfer and to make the node power consumption 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.
