Abstract--We illustrate the transport layer unfairness problem
in the IEEE 802.11 Wireless Local Area Networks (WLANs). We
design a link layer access control block for the Access Point
(AP) in order to provide fair Transmission Control Protocol
(TCP) access in an 802.11 infrastructure Basic Service Set
(BSS). The novel and simple idea of the proposed control block
is employing a congestion control and filtering algorithm on
TCP Acknowledgment (ACK) packets of uplink flows, thereby
prioritizing the access of TCP data packets of downlink flows
at the AP. We quantify the parameters of the proposed ACK
congestion control and filtering algorithm based on the measured
average downlink TCP data access rate. Via simulations, we show
