摘要
标准TCP把Adhoc网络中的移动丢包也解释为网络发生了拥塞 ,从而启动拥塞控制 ,造成TCP性能的下降 .simELFN技术利用中间节点的反馈信息并结合路由协议自身的特性 ,能区分丢包的本质原因 ,并且能避免其他反馈方法所面临的多个重复确认问题 .经过分析和仿真表明simELFN能够有效地提高TCP性能 .
The mobility loss in Ad hoc network is misinterpreted a s congestion loss in standard TCP. Poor TCP performance is caused by invoking co ngestion control action. simELFN can distinguish the essence of packet loss and the problem of consecutive dupACKs will not arise based on feedback from interme diate nodes and some properties of routing agent. The analyses and simulations s how that simELFN can improve TCP performance in Ad hoc network efficiently.
