Abstract: Multipath routing protocols in mobile ad hoc networks can achieve more than one path between source and destination nodes,they can reduce the delay of route discovery and increase the routing stability,so they attract many people’s attention.The mechanism and characteristic of AOMDV protocol is detailedly analyzed,the performance of the protocol is evaluated from the load balancing point of view,the simulation shows that it can increase living time of the network;and then a scheme that can avoid the disorder problem of TCP protocol when several paths is brought,the simulation shows that the scheme can increase the throughput of TCP protocol.

摘要: Ad Hoc网络中的多径路由协议可以获得源节点和目的节点之间的多条路径,能够减小路由发现延迟,提高路由稳定性,受到了人们的广泛关注。详细分析了AOMDV多径路由协议的机制和特点,从负载均衡的角度仿真评估了AOMDV协议的性能,研究表明可以显著提高网络整体生存性。在此基础上提出了一种优化的负载均衡传输方案,能够减小TCP在多径传输时的乱序问题,仿真表明显著改善了TCP传输的吞吐量。
