This paper proposed an adaptive scheduling algorithm for real-time video streams in wireless local area networks (WLAN). The first job is how to reduce the amount of the video data that must be transmitted on the wireless channel. The second job is how to scheduling the video streams at the access point (AP) and achieving the best overall quality of service (QoS). For the first job, we will compare the deviation of two consecutive frames in the video stream and decide whether or not the follow-up frame should be transmitted. If the deviation of two consecutive frames not reach the threshold, the latter frame will be discarded, and the former will be keep in the server. Otherwise, it will be transmitted. We adaptively adjust the threshold at server to reduce the traffic load over the wireless channel. For the second job, the AP uses different scheduling policy at different stage according to the wireless traffic.
