Cross-layer scheme for WiMAX video streaming

A cross-layer approach is applicable to wireless systems and demanding video streaming applications. Sharing the channel state from the physical layer with the application layer allows an adaptive protection scheme to be deployed. Flexible error correction is made possible by rateless coding. To protect against outright packet drops, unequal protection of more important compressed data occurs. The system is evaluated in terms of mean video quality, bitrate, and latency for constant bitrate streaming.
