Abstract: TFRC (TCP (Transmission Control Protocol) Friendly Rate Control) has been widely used in wired networks for its enhanced friendliness and fairness. However, TFRC cannot distinguish between packet losses due to network congestion and those due to wireless link error in wireless networks. Thus, in this study an improved TFRC scheme that is able to differentiate between congestion losses and wireless link error losses for wired/wireless hybrid network is proposed. Specifically, the improved TFRC scheme utilizes the information of the one-way delay to regulate the transmission rate at the sender and simulation experimental results show this strategy is effective and performs much better than the traditional TFRC.
