摘要
多数无线传感网络应用中需要处理节点移动性,为此,面向移动无线传感网络(M.WSNs),提出基于接触时间的区路由(CTAR)。CTAR路由先利用源节点和目的节点的相对位置信息形成活动区,只有区内的节点才能参与路由;然后,利用节点的移动矢量信息选择能够最大化接触时间的邻居节点作为下一跳转发节点。仿真数据表明,与RoF协议相比,CTAR协议的数据包传递率得到有效提高。
The node mobility needs to be processed in most applications of the wireless sensor network. Therefore,a contact time-area based routing(CTAR)is proposed for mobile wireless sensor networks(M-WSNs). In the CTAR,the relative position information of the source node and destination node is used to form the active region,and only nodes within the region are allowed to participate in routing. The mobility vector information of the node is used to select the neighbor node that can maximize the contact time as the next-hop forwarding node. The simulation data shows that the data packet delivery ratio of the CTAR protocol is effectively improved in comparison with that of the RoF protocol.
