摘　　要：为了延长无线传感器网络的生命期,针对节点能耗分布不均匀的问题,提出一种电量均衡的分簇算法。该算法将节点剩余能量作为构建分簇结构的依据,对剩余能量较少的节点赋予一定的约束,使之成为普通节点,并使电量多的节点成为簇头节点,均衡网络电量负载,解决了网络中部分低电量节点担任骨干节点而导致能耗的问题,从而有效延长了网络的生命期。仿真实验证明了该算法的有效性。In order to extend the network life of Wireless Sensor Network （WSN） and solve the problem of unbalanced power distribution of WSN nodes, a power- balanced cluster algorithm is proposed, which differentiates nodes according to their remained power. The nodes with low energy are set to be ordinary nodes,while the nodes with high energy to be distin-guished nodes,so as to balance the network load and solve the problem that the energy consumption of some nodes in network is too fast due to over load of distinguished nodes. Experiment result shows the effectiveness of this algorithm.
