面向无线多跳网络的TCP协议改进研究综述

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。

Survey of TCP Improvement over Wireless Multi-hop Networks

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 ...
