摘　　要：节能和延长网络生存时间是无线传感器网络研究领域的热点问题.该文综合考虑网络中节点的剩余能量和节点间传输数据的能耗,基于最短路径树算法,通过构造两种不同的权值函数,提出了"比例权值路由算法"(Ratio-W)与"和权值路由算法"(Sum-W).仿真分析表明,所提出的算法可以延长网络生存时间,并使能耗经济有效,比一些已有知名算法更优.Saving energy and prolonging network lifetime are key issues of wireless sensor networks. Based on shortest path tree,ratio weight （Ratio-W） and sum weight （Sum-W） routing algorithms are proposed,in which both remaining energy of nodes and energy consumption for delivering packets on wireless links are considered. Simulation exhibits the Ratio-W and the Sum-W can prolong network lifetime and make energy consumed efficiently and effectively. In addition, the proposed algorithms outperform some well-known muting algorithms in terms of network lifetime and energy consumption.
