Wireless Local Area Network (WLAN) brings the users a low cost and high bandwidth experience and thus plays a critically important role in current/future networks to support high-rate transmissions. To better provide Quality-of-Service (QoS) for WLAN users, the authors in this paper propose an improved scheme called \"A-EDCA\" (Adaptive EDCA), based on Enhanced Distributed Channel Access (EDCA) of IEEE 802.11e under the infrastructure mode. Their proposed scheme aims at efficiently adapting the transmission over WLAN to the time-varying network conditions and mitigating the competition ability unfairness between Access Point (AP) and non-AP STAtions (STAs).
