摘　　要：由于无线传感器网络具有能量有限等特点,如何高效的使用能源已成为人们研究的热点。结合已有的研究,提出了一种基于节能的分簇路由算法。节点分成簇间与簇内两级拓扑结构,簇内节点通过在最后一个数据包中"捎带"自身剩余能量信息参与下一轮簇头节点的选举,簇头节点之间形成网状拓扑结构,并维持一张由邻居节点梯度、距离及剩余能量值组成的权值路由表,通过尽量选择权值最小的路径进行数据的传输,实现节能、均衡能量消耗、延长网络生命周期的目的。On account of limited energy of wireless highlight that people invested. An energy-saving-based sensor network, how to use energy efficiently has become a cluster routing algorithm is proposed combined with existing researches. Nodes are divided into two levels of network topology named cluster head and cluster member. The latter is concerned with next round for cluster head election via the last data package by using piggyback of surplus energy information of itself. Network topology is formed between cluster heads carrying through a sheet of weight routing table that consists of neighbor node grads, distance and remained energy. To carry out a motive of energy-saving, equilibrium of energy consume and prolonging network lifecycle, the routing table exerts itself to select the path of shortest weight to transmit data.
