When TCP operates in wireless networks, it suffers severe performance degradation because TCP's Fast Retransmit/Fast Recovery (FR/FR) is often triggered regardless of congestion when a packet is lost due to wireless transmission errors. Although several loss differentiation schemes have been proposed to distinguish the cause of triggered FR/FRs, there has been a little try to find out an appropriate responding method to utilize the detection information of a LDA. In this paper, the authors observe the relationship between a responding method and TCP's performance, and investigate the best way to respond to the FR/FRs non-related to congestion in order to improve TCP's performance to the max.
