This paper proposes and analyzes the performance of streaming video transmission over IEEE 802.11 WLAN. A simple but robust bandwidth allocation method is proposed to enable dynamic update of transmission schedule on the AP (access point). With a continuous trace of status of each video stream channel, the proposed scheme can efficiently reclaim and reallocate the network bandwidth, leading to minimizing the wasteful transmission on the bad channel, without jeopardizing the timely transmission of other active streams. Simulation result shows that the proposed scheme can keep the actual packet error rate less than 5%
