The demand for end-to-end Quality of Service (QoS) in Wireless Local Area Networks (WLANs) is becoming ever more important due to the trend towards converged communication networks. The recently accepted QoS mechanism in WLAN: the IEEE 802.11e has limitations in providing fairness to different types of traffic. The authors proposed Dynamic Weighted Fair Scheduling Scheme (DWFSS) to improve fairness in WLANs by enhancing the IEEE 802.11e. The DWFSS allocates bandwidth to four different classes of traffic. These classes are assigned weights which are dynamically changed.
