Abstract :
This paper proposed an adaptive video transmission control scheme in wireless networks. The first job is how to reduce the amount of the image data that must be transmitted on the wireless channel. We 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 not be transmitted but discarded, and the former will be keep in the server. When a frame´s difference factor reaches the threshold, it will be transmitted. In the case of the heavier wireless load, the server will increase the threshold. Therefore, the transmission load will be decreased. We use a difference factor to show how much two consecutive image frames is different. We adaptively control the transmission quality at server according to the traffic load over the wireless channel.
