Abstract :
Widely deployed IEEE802.11 WLAN brings fairness problem among wireless stations (STA) in Wi-Fi hot spots. The reason of the unfairness is analyzed from two aspects in this paper, TCP-induced and MAC-induced asymmetry. We propose an adaptive CWmin approach to assure fairness between download and upload flow at AP. And also propose a user-fair download channel allocation algorithm. The novel aspect of these approaches is that it does not entail any modification of the IEEE 802.11 MAC protocol in STAs and easy to deploy. The simulation results indicate that the proposed approach can provide fairness to all STAs.
