摘　　要：针对无线传感器网络分簇路由协议中簇头节点负载过重的问题,提出一种基于双簇头的多跳路由协议,该协议基于LEACH产生主簇头,然后根据节点的剩余能量及其与主簇头的距离产生副簇头,以负责数据转发的任务,减轻主簇头的负载,并在各副簇头之间形成簇间路由,将数据以多跳的方式传送到基站。仿真实验表明,与LEACH相比,该协议较好地均衡了网络的能量消耗,延长了网络的生命周期。Cluster heads are always overloaded in wireless sensor network routing protocols.A multi-hop routing protocol based on double cluster-heads was proposed.It generated the main cluster head according to the LEACH protocol,and then a vice cluster head,which was responsible for forwarding data to reduce the load of the main cluster head,was generated when both the residual energy of node and its distance from the main cluster head were taken into consideration.The multi-hop routing protocol built an inter-cluster routing among vice cluster heads and transmitted data to the base station in multi-hop manner.Simulation results showed that the protocol was more effective than LEACH in balancing energy consumption and prolonging the life cycle of the network.
