Abstract
Standard TCP has been developed for wired networks and stationary hosts. In wireless networks, consecutive handoffs between access points introduce packet loss that TCP will consider as an indication of congestion, which is followed by a reduction of its congestion window. This will result in a considerable degradation of the performance in terms of throughput, although sufficient bandwidth is available between handoffs. In this paper we present the design of a TCP protocol booster, which combines retransmissions based on negative selective acknowledgements, delayed duplicate acknowledgements and detection of congestion in order to protect the sender in a transparent way from the handoff packet losses. A test-bed implementation demonstrates that the booster improves the TCP performance considerably in a wireless network.
