Cross-layer optimized multipath video streaming over heterogeneous wireless networks

摘要

In this work, we propose a cross-layer optimized multipath video streaming system over heterogeneous wireless networks. The proposed system uses multiple paths over wireless mobile networks in order to satisfy the quality-of-service requirements for seamless high-quality video streaming services and adopts fountain codes to handle the effect of lost packets over wireless networks efficiently. Moreover, a cross-layer approach is used to determine the code rate of fountain codes efficiently. Finally, the proposed system is implemented and tested in real environments.
