摘要
由于能量的限制,无线Ad hoc网络面临网络生存时间、无线资源利用效率以及时延要求等方面的挑战。为了降低网络的能量消耗,延长节点寿命和网络生存周期,提出了一种基于区域代价的功率感知路由协议。该协议在路径选择时,综合考虑节点及其邻居的剩余能量、节点发射功率和节点接收处理功率等因素,使网络中节点的能耗趋于一致,并延长网络的生存时间。该算法的复杂度不高,易于在节点运行。仿真结果证明该协议能取得较好的性能。
Due to energy limitation, the wireless Ad hoc networks faces to the challenge of lifetime, wireless resource utilized efficiency and delay. This paper proposed a region-cost based power-aware routing protocol for reducing energy consumption and extending the survival period of networks. In route selecting, this protocol synthetically considers the factors of reserving energy of node and its neighbor, transmitting power, and receiving process power etc. So this protocol lets the energy consumption of nodes tend to keep at same level, and prolongs the lifetime of networks. This protocol has lower complexity to carry out at nodes, and the simulation results show it can achieve well performance.
