摘要 Ad hoc网络中按需路由协议AODV是被广泛应用的路由协议之一。该文针对AODV路由协议本身在路由发现的过程中并不考虑节点当前的负荷,可能导致局部的网络拥塞。因此,结合模糊控制理论、随机早期检测的拥塞控制思想,对AODV路由协议的路由发现阶段数据包的转发进行动态控制。最后利用ns2仿真,结果表明改进后的协议在降低了平均延时、路由负荷和丢包率的同时,提高了节点数据转发能力。 AODV routing protocol a recommended one by the IETF's MANET working group.However,AODV routing protocol itself does not take into account the current load of nodes in the process of route discovery,so it may result in localized network congestion.The modified routing protocol which combines fuzzy control theory with random early detection ideas carries on the dynamic control for data packets during route discovery of AODV.The ns2 simulation shows that the modified protocol reduces the average delay,routing load and packet loss rate while increasing the data forwarding capacity of nodes.
