Abstract-- Most of the deployed IEEE 802.11 Wireless Local
Area Networks (WLANs) use infrastructure Basic Service Set
(BSS) in which an Access Point (AP) serves as a gateway between
wired and wireless domains. We present the transport layer
uplink unfairness problem that occurs due to uneven bandwidth
sharing between upstream Transmission Control Protocol (TCP)
data and downstream TCP acknowledgment (ACK) packets. We
propose ACK congestion control and filtering in the WLAN
downlink to improve fairness between uplink flows. Through
extensive simulations, we show that the proposed heuristic algo-
rithms not only enhance both short- and long-term fairness but
