Different from wired networks, TCP over wireless networks needs to be cross-layer designed which depends on information of MAC. However, it is difficult to apply existing cross-layer design into hybrid networks. Based on researches of congestion metrics from MAC layer over wireless networks, this paper proposes an cross-layer ECN scheme that TCP sender will trigger congestion control by ECN if RTS...
TCP was designed to perform on wired networks, where packet loss is mostly caused by congestion, as compared to wireless networks, where losses due to error in channel are more likely. Hence TCP respond to all kind of losses by invoking congestion control and avoidance schemes resulting in performance degradation. Several solutions for the improvement of TCP over wireless link have been proposed which...
Some physics researchers retrieve EAST experiment data using the Transmission Control Protocol (TCP) in a wireless local area network (WLAN). TCP is the most commonly used transport control protocol. It assumes that every packet loss is caused by network congestion and invokes congestion control and avoidance. TCP's blind congestion control results in degraded performance in lossy wireless networks...
