Abstract : A cross-layer optimization concept for wireless multi-user video streaming is proposed. We describe a cross layer optimizer that interfaces the video streaming application and the radio link layer by means of parameter abstraction. The optimizer maximizes the end-to-end quality of the video streaming service jointly for all users while efficiently using the wireless resources. Our simulation results for video streaming in a multi-user environment show the performance improvements achievable with this concept. We demonstrate that even for a small number of users and a small number of degrees of freedom in the optimization significant quality improvements can be obtained.
