英文摘要：

In wireless mesh networks, the performance of TCP degrades rapidly due to the interference of the wireless channels and large amount of resource occupation. We propose a modal joint the delay distribu- tion and TCP control mechanism on packet drop rate to deal with this problem. Firstly, this delay model can capture the delay exactly that a packet experiences at one hop transmission with rigorous theoretic derivation and lower overhead, ~computational complexity, then analyze the character of the wireless packet loss,fur- thermore, with the combination of the delay distribution and character of the wireless packet loss, it point out the control method at transport layer to deal with the different type of packet loss, finally, the simula- tion results show that our mechanism can decrease the packet drop rate efficiently.
