This paper describes an adaptive and dynamic tuning method of the operation parameter value in wireless LANs. That is, the mechanism for QoS (quality of service) in EDCA (enhanced distributed channel access) of IEEE 802.11e. For this purpose, the HC (hybrid coordinator) in QAP (QoS access point) defines the required QoS level of the traffic to service by QoS elements such as throughput and delay. And HC adjusts the operation parameter value according to the relative ratio of each QoS element value. When needed, HC readjust that parameter value dynamically using the collected data during wireless LAN service. This proposed tuning mechanism is evaluated via simulation.
