摘要 在AdHoc网络中,由于网络节点的移动性及拓扑结构的易变性,路由成为最受关注的问题。为了克服在路由算法中,节点的信息存储量大、路径使用效率低下、路由开支庞大等问题。提出了一种加权可靠路由策略W-RR。在该策略中,每个节点都保存稳定性、开销以及邻居节点信息,在进行选路时,对路径的可靠性进行加权,并利用定位系统在源节点和目的节点之间选择一条加权可靠性最大的路径。仿真结果表明,该路由策略在可靠性、建路时间、选路成功率、路径的开销和信息量等方面都具有较好的性能。 In Ad Hoc network,routing has been the most focused area for its nodes＇ mobility and topology variability.In order to solve the problems like large saved messages in every node,low efficiency in used road and huge cost in routing.In order to solve these problems,proposed a Weighted-Reliable Routing scheme （W-RR） in which every node saves the stability,cost and messages of neighbor nodes.The middle nodes compute the weighted-reliability of the previous part route after received the messages of routing and choose one message to send to next nodes under the help of GPS.The destination finds the maximum weight-reliable route finally.Simulation results show that the scheme could use less messages and less delay to choose road,improves the performance of Ah Hoc.
