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...
This study proposes a novel method of evaluating hierarchical relationship between QoS and QoE for Web services by utilizing the path analysis and the principal component analysis. The proposed method shorten the number of QoS parameters each layer with the principal component analysis; it then clarify the relationship between the QoS and the QoE by performing the path analysis. To confirm the effectiveness...
In this paper, the authors develop a novel wireless LAN base station with Web-QoE based QoS control and evaluate its performance by experiment. By adapting a statistical characteristic of Web service traffic to QoS control, the base station can keep high QoE without worsening of congestion over wireless LAN; it is implemented by adopting two technologies: OpenFlow and WMM. In the experiment, the authors...
This paper empirically studies clarification of complex relationships between hierarchical QoS and QoE for Web services with the method using the path analysis. In the experiment, the authors treat three Web services and consider 10 parameters of three-layered QoS and four QoE parameters; they suggest a new model for a path diagram. The obtained path diagrams give high goodness-of-fit, 0.916, 0.915,...
