Performance analysis and comparison on improved schemes of TCP in MANET
Qinghong Liu · Jisuanji gongcheng yu sheji · 2007
As TCP protocol is designed for wired network originally,it congestion control mechanism is triggered into action when packet loss is detected. But the high bit error rate and node changing also should invoke packet loss in MANET. Such non-congestion packet loss,when dealt with by congestion control mechanism,cause poor TCP performance. The factors is analyzed,which affect TCP performance in MANET. And an overall view on some cross-layer work mechanisms of the improved schemes of TCP in MANET from the three levels are presented including the transmission level,the network level and the link level. Then the analysis and compare of these methods are given. Finally the future work is pointed out.
