While Transmission Control Protocol (TCP) is the most popular transport protocol used in terrestrial networks, its performance is not adequate in wireless networks with long delay, e.g., satellite networks. Though some improvements of TCP and new transport protocols have been proposed, we focus on Variable-structure congestion Control Protocol (VCP) designed for high Bandwidth Delay Product (BDP)...
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...
