%X TCP(Transmission Control Protocol) is a widely used reliable transmission protocol,and it is designed on such assumption that most packet losses are caused by congestion.But in wireless networks,packets are lost usually because of bit-errors,which causes dramatic performance declining.Many current methods to improve TCP performance over wireless networks are TCP-aware.This paper proposed an alternative "TCP-unaware" scheme that is suitable for encrypted TCP traffic.It makes TCP source be capable of differentiating a loss due to congestion in the wired network from a loss due to bit-errors in wireless networks.Simulation results show that the scheme can improve TCP performance significantly in both LAN(Local Area Network) and WAN(Wide Area Network).
