Congestion-optimized scheduling of video over wireless ad hoc networks
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.
