摘要

Improving TCP performance has long been the focus of many research efforts in 802.11 wireless networks study. Hop-count and Round Trip Time (RTT) are the critical sources which serious affect the TCP performance on end-to-end connection. In this paper, we analytical derived the affection and based on the analysis we propose TCP should Change its Expected Value (TCP-CEV) when hop-count and RTT change by setting a reasonable CWND change rate to improve the performance. The proposed scheme is applicable to a wide range of transport protocols using the basic TCP mechanism, and the protocol behavior is analytically tractable. We show that our simple strategy improves TCP performance at least over 12% in a chain topology and improve the TCP convergence.
