Estimation of appropriate transmission rate via a IEEE 802.11 wireless LAN based on WebQoE

This paper discusses the most appropriate transmission rate of IEEE 802.11 wireless LAN based on QoE for Web services. Since some QoS parameters have trade-off relationship between each other for the transmission rate, it is difficult to decide the appropriate value of the rate. Thus the authors clarify the relationship between QoE and QoS for Web services by the linear multiple regression analysis. They then adapt measured values of the packet loss rate and those of RTT as QoS parameters for the relationship, and estimate the transmission rate which maximizes the QoE. The authors targeted two actual Web services; shop service and map service; they performed experiments. Their experimental results show that the highest satisfaction can be given when the transmission rate are 9.125 Mb/s and 24.472 Mb/s for the shopping service and the map service, respectively.
