介绍了无线自组织网和AODV路由协议,对AODV协议进行了研究分析,提出了一种优化方案。方案对原Hello消息机制进行了改进,使节点可以利用Hello消息交换路由信息,从而建立备份路由。通过在NS-2中对改进的协议进行仿真模拟,发现与传统AODV协议相比,该方案可以减少断路后重新找到路由的时间,有效提高了Ad Hoc网络的吞吐量,降低了时延,从而有效地提高了网络的性能。
Introduced wireless ad hoc networks and AODV routing protocol, the AODV protocol was studied and analyzed, and an optimization scheme was proposed. The scheme improves the original Hello message mechanism so that nodes can use the Hello message to exchange routing information to establish a backup route. By simulating the improved protocol in NS-2, it is found that compared with the traditional AODV protocol, the proposed scheme can reduce the time for re-finding the route after the disconnection, effectively improve the throughput of the Ad Hoc network and reduce the delay Effectively improve the performance of the network.
