摘　　要：针对无线传感器网络LEACH路由协议簇头分布不均匀、网络拓扑和能量消耗不均衡的问题,提出基于DCHS簇头选择策略的无线传感器网络LEACH路由协议的簇头多跳算法LEACH-MUL。该算法在非簇头节点中选择一个节点作为通信簇头节点,其它簇头节点进行融合后的数据发送到该簇头节点并进行数据再次融合,最后通信簇头节点将数据融合后的结果数据发送到基站BS。LEACH-MUL算法能够有效地均衡节点能耗,提高能量利用率,延长网络寿命。To solve the problem of cluster-head in LEACH protocol odds distribution,network topology and Energy consumption imbalance,a new protocol adopt cluster-heads multi-hop algorithm（LEACH-MUL） which based on the basis of LEACH DCHS cluster head selection strategy was proposed.In this algorithm a communication of cluster nodes in the non-cluster head node is chosen to receive the data fusion of cluster nodes.Then data are fused,and sent to BS.The nodes selected for the communication of cluster nodes will no longer join any cluster.The simulation result show that LEACH-MUL effectively balance the energy of the whole network and extend the network lifetime.
