Abstract :
We analyze the benefits of information sharing between the application layer and the transport layer, for streaming video encoded at several different qualities, in a mobile wireless network. The application relies on statistics collected at the transport layer and on a video distortion model to select the highest quality that can be supported by the network. At the transport layer, congestion-distortion optimized scheduling is performed to select packets which maximize the received video quality. Experiments performed over a simulated multi-hop wireless network, with H.264 encoded video, show benefits of the proposed approach.
