A Wireless TCP Protocol for Throughput Enhancement in Wireless Broadband

In this paper, we investigate the wireless TCP protocol for throughput improvement in wireless Broadband. If the burst error duration of a wireless link is significantly long, retransmissions of lost packets by Snoop TCP are fulfilled mainly not by the receipt of duplicate acknowledgement (DUPACKs) but by local timer expiration. With the proposed scheme, Snoop TCP recovers packet losses fast by shortening the interval of local retransmissions based on the channel status. From the simulation results, we can show that the proposed scheme can improve TCP throughput considerably.
