摘　　要：无线多跳网络应用日益广泛,但它的特殊性如共享无线信道、多跳连接、节点移动等,使得针对有线网络设计的TCP协议不能很好地工作在该网络环境中,经常误判网络拥塞状况而且反应迟钝,严重损害了网络性能。本文深入分析无线多跳网络中影响TCP性能的因素,总结目前提高TCP性能的改进方案并对这些方案进行比较,为无线多跳网络中TCP的研究方向提供参考。The specific characteristics of wireless multi-hop networks,which applications are rapidly expanded,such as shared media,multi-hop connection and node mobility cause TCP designed for wired networks not to work well.TCP often misjudge the congestion status in such kind of networks with a slow reaction to it,which seriously suffers from performance degradation.This paper analyzes the factors affecting TCP performance,then some research works to improve TCP performance are summarized and compared.Finally,some possible research trends of optimizing TCP performance over wireless multi-hop networks are proposed.
