Abstract	The next generation wireless networks need to support video traffic. A major challenge in video services over wireless networks is quality of service (QoS) provisioning. We propose a cross-layer protocol stack architecture for wireless video transmission. In the architecture, the application layer provides the link layer with video compression information. Using this information, a dynamic-weight generalized processor sharing (DWGPS) discipline is proposed for the link layer resource allocation, which is aimed at providing the application layer with strong protection to high priority traffic. The weights in DWGPS are selected based on an optimization problem. Over time-varying wireless channels, a multiuser diversity gain can be achieved without much modification to DWGPS. Simulation results demonstrate the effectiveness and efficiency of DWGPS.
