Queue Management Mechanism for 802.11 Base Stations
This paper presents a novel queue management mechanism for base stations in infrastructure IEEE 802.11 networks. The mechanism is transparent to high-level protocols and is compatible with the standard. Its effectiveness is illustrated by showing that it can ameliorate the RTT unfairness and the MAC anomaly problems in wired-cum-wireless networks. In wired-cum-wireless networks, the wireless link usually becomes the bottleneck of the end-to-end path, making the management of the Base Station (BS) buffer a key point for performance enhancement.
