application-driven cross-layer design of multiuser h.264 video transmission over wireless networks
An application-driven cross-layer design of multiuser H.264/AVC video transmission over wireless networks is proposed in this paper. An objective function for cross-layer optimization is developed based on the parameters abstracted from the application layer, the media access control layer and the physical layer. Our objective is to maximize the video perceptual quality after delivery with constraint of the limited wireless resources. Simulation results show that the proposed scheme performs significantly than the conventional scheduling schemes for video transmission.
