摘　　要：在原有的LEACH协议分簇算法的基础上,针对无线传感器网络中节点分布不均匀的情况,以节点的剩余能量与节点到基站的距离相结合来改进其阈值,作为节点成为簇首的随机数值的调整权值,改进其LEACH协议分簇算法。仿真实验结果表明,该改进的算法有效地均衡了节点的能量消耗,可以显著地延长网络的寿命周期。On the basis of the original LEACH protocol clustering algorithm, to the situation of the uneven distribution of nudes in wireless sensor network（ WSN）, this paper improves the threshold with acombination of the node~ ersidual energy and the distance of the node to the base station. As the cumulative ralue of the radom value when the node becomes the cluster head, this paper improves its LEACH protocal clustering algorithm. The simulation experiment results show that the improved algorithm can effectively balance the node energy consumption, can significantly prolong the life cycle of the network.
