Adaptive Scalable Layer Selection for Video Streaming Over Wireless Networks
In this paper, the authors propose an adaptive scalable layer selection policy for video streaming over wireless networks by jointly considering the wireless channel conditions and scalable video coding. Their goal is to design a scheme which could provide both long-term smooth and high play-back quality for each user, while maintaining the fairness among multi-users. They first design an adaptive long-term layer selection scheme which determines the number of layers each user would receive in order to maximize the total video quality of all streams while avoiding high variation in the number of video layers. They then employ a scheduling algorithm for slot allocation considering both current channel capacity and deadline.
