Abstract: | To achieve the mobility of computers during communication, the TCP connections between fixed host and mobile host may often
traverse wired and wireless networks, and the recovery of losses due to wireless transmission error is much different from
congestion control. The paper analyzes the side effect of RTT estimation while making the TCP source to handle congestion
and wireless error losses properly. Then present a strategy using information feedback by the last hop acknowledgement and
monitoring the queuing level of the wired bottleneck link by calculating the changes in transmission delay along the path.
With the identification of the early stage of congestion, it can respond to wired congestion quickly while keeping wireless
link more reliable, and make TCP react to the different packets losses more appropriately.
