Abstract(in English) In wireless LAN, since an access point is shared by several terminals, there is a problem that communication quality of video streaming is affected by background traffic of TCP. Therefore, we propose priority control for improving quality of video streaming by setting EDCA (Enhanced Distributed Channel Access) parameters in an access point. In addition, we also propose a cross-layer control to adjust the bandwidth, and set TCP window size of TCP from wireless terminals according to the congestion status. In evaluation, we construct the testbed and the proposed method shows improvement of QoE for the video streaming.
