摘　　要：在无线传感网络(Wireless Sensor Networks,WSNs)中引入移动信宿可以缓解热点问题。然而,向网络内所有节点更新信宿位置增加了网络开销和节点的能耗。为此,提出一种基于环形的层次型路由协议(Ring-based Hierarchical Routing,RBHR)。RBHR将感测区域分割成多个环,仅向环上节点更新Sink位置信息。同时,RBHR引用基于角度路由向信宿传输数据,缩短路径长度。仿真结果表明,相比同类的路由,RBHR的能量消耗,数据传输时延和数据包传递率性能均得到提升。Mobile Sinks are introduced in Wireless Sensor Networks(WSNs)to mitigate the hotspot problem.However routing in mobile Sink based WSNs requires frequent updating of Sink location information to all the sensor nodes,and this results in the increasing of network overhead and energy consumption.Therefore,Ring-based Hierarchical Routing(RBHR)is proposed.The RBHR route divides the sensing region into multiple rings and updates the Sink location information only to the nodes on the ring.At the same time,angle based routing is integrated with RBHR to transmit data to mobile Sink to shorten length path.Simulation results show that RBHR outperforms existing routing protocols in terms of energy consumption,data delivery delay,and packet delivery ratio.
