摘　　要：簇结构是减少无线传感网能耗的基础,针对经典LEACH协议簇头能耗不均衡的缺点,提出了一种适用于异构传感网中的基于圆环域的簇头混合通信的路由算法LEACH-RMC。该算法通过在监测区划分圆环域确定簇头的等级,簇头采用单、多跳结合通信方式均衡了簇头的能耗。网络中采用固定簇头,节省了普通节点的硬件花费。实验表明,新的算法明显延长了网络的生存期,均衡了簇头的负载。Clusters structure is the basis of decreasing WSNs＇ energy consumption.According to the cluster-heads＇ unbalance energy consumption in classical protocol LEACH, propose a routing algorithm LEACH-RMC,which ring-zone-based with clusterheads＇ hybrid communication modes applicable to heterogeneous WSNs. Make use of dividing the sensor field into some ring zones to determine the level of the cluster-heads, and combine single-hop and multi-hop to communicate which has balanced the energy consumption of the cluster-heads.Using fixed cluster-heads in the networks has saved hardware costs of normal nodes.The simula- tion results show that the new algorithm obviously extend the span of WSN＇s lifetime and balance the load of the cluster-heads.
