Explosive growth of applications for wireless networks and increasing number of users will cause significant increase in the traffic over radio channels. Consequently, uplink and downlink channels may suffer serious traffic congestion problems in the absence of effective congestion control schemes. One approach to enhance the performance of wireless services is to employ an AQM scheme for buffers at the downlink of wireless networks. This paper presents an analytical framework for the performance evaluation of AQM scheme based congestion control mechanism in WLANs. It also carries out a comprehensive performance comparison for various dropping strategies to see the impact of AQM scheme on WLANs using queue thresholds.
