| 摘 要： | 在移动自组网(mobile ad hoc networks,简称MANET)中,节点的移动使无线链路经常发生断裂,从而导致路由无效.为了提高路由的稳定性,在分析单跳链路的t-时间维持概率的基础上,提出了一种基于路径t-时间维持概率的按需路由协议.该协议通过目的节点对路由请求的二次应答和中间节点对路由的反向优化来选择具有最大t-时间维持概率的路径,从而延长了路由的维持时间.仿真结果表明:与AODV(ad hoc on-demand distance vector)和DSR(dynamic source ro

| Abstract: | In mobile ad hoc networks (MANET), node movement often makes the wireless link break, and results in the routing invalidation. In order to improve the stability of routing, based on the analysis of the time-t holding probability of single link, an on-demand routing protocol is provided based on the time-t holding probability of a whole path. With double reply of routing request from destination and reverse optimizing of middle nodes, this protocol chooses the path that has the maximal time-t holding probability as the best routing. Simulations show that, compared with AODV (ad hoc on-demand distance vector) and DSR (dynamic source routing), this protocol saves the overhead of the protocol and reduces the end-to-end delay of the packet. |
