A study on adjusting EDCA parameters of QoE-based wireless LAN base station

This paper studies appropriate values of EDCA parameters of the author's wireless LAN base station based on Quality of Experience (QoE) for Web Services by experiments with subjects. The base station reduces the traffic of a Web service without degradation of QoE; it utilizes EDCA as QoS control. However, appropriate EDCA parameter value have never been studied. This paper evaluates QoE and measures QoS for combinations of four EDCA parameters by experiment with subjects; the results, show appropriate values of EDCA parameters for two actual Web services: Amazon and Google Map.
