摘　　要：针对现有无线传感器网络(WSN)协议中更多消耗sink附近节点能量导致网络寿命短的问题,提出一种基于簇的无线传感器网络交会路由协议(Cluster-based Rendezvous Routing Protocol,CRRP);该协议在网络的中间构建交会区域,该交会区域划分整个网络区域并在传感器节点之间分配网络负载,延长了网络寿命;此交会区域内的节点分为不同的簇,每个簇的簇头(CH)负责不同簇之间的通信,sink在此交会区域内发送其更新的位置信息,并且当传感器节点想要发送数据时,会从该交会区域检索sink的当前位置信息并直接将数据发送到sink;仿真实验结果表明,在能耗与网络寿命性能方面,所提CRRP协议优于Rendezvous协议、LBDD协议、Railroad协议和Ring协议。In order to solve the problem of shorter network lifetime caused by more energy consumption of nodes near sink in existing WSN protocols,a cluster-based rendezvous routing protocol(CRRP)for wireless sensor networks was proposed.The protocol builds a rendezvous area in the middle of the network.The rendezvous area divides the entire network area and distributes network load among sensor nodes,which prolongs the network lifetime.The nodes in this rendezvous area are divided into different clusters,each cluster has a cluster head(CH),which is responsible for communication between different clusters,and the sink sends its updated location information in this intersection area,and when the sensor node wants to send data,it retrieves the current location information of sink from the rendezvous area and sends the data directly to the sink.Simulation results show that CRRP protocol is superior to Rendezvous protocol,LBDD protocol,Railroad protocol and Ring protocol in terms of energy consumption and network lifetime performance.
