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 possible research trends of optimizing TCP performance over wireless multi-hop networks are proposed.
