| 摘 要： | 为了改善移动Ad Hoc网络环境下TCP的性能,对AODV的改进协议OAODV协议做了一定的修订,得到E-OAODV(Enhanced Optimal Ad HOC On-demand Distant Vector)协议.该协议通过在路由失效时使用来自目的节点的ACK应答信号所包含的路由信息来尝试继续传输数据,同时通过对OAODV和TCP两者的修订来实现在路由重建后尽可能地恢复因路由失效所丢失的数据包.NS-2下的仿真结果表明,E-OAODV对断线点离源节点较近的情况下的TCP性能有较显著的改善,尤其在路由总跳数较大时.

| Abstract: | In order to improve the performance of TCP used in Ad Hoc networks,an enhanced routing protocol based on AODV was presented,which is called E-OAODV(Enhanced Optimal Ad Hoc On-demand Distant Vector)in this paper.By using routing information included in ACK returned from destination nodes,E-OAODV tries to transfer data to destination node while routing failures occurred.And at the same time,with modifications in both TCP and OAODV,E-OAODV tries its best to recover the lost data caused by routing failures.By N... |
