• This paper proposes and analyzes the performance of streaming video transmission over IEEE 802.11 WLAN. The simple bandwidth allocation method was proposed first to enable dynamic update of transmission schedule on AP. With a continuous trace of channel status of each video stream channel, the proposed scheme can efficiently utilize the network bandwidth, as it minimizes the useless transmission on the bad channel, without jeopardizing the timely transmission of other active streams. Simulation result shows that the proposed scheme can achieve as high as 91.2 % of achievable bandwidth.
