Abstract
Wireless multimedia service is considered a promising application in the near future. However, current layered protocol stack is not conductive to provide adaptive multimedia streams in instable wireless environment. In this paper, a new Cross-Layer mechanism is proposed to solve this problem. A scalable video encoder can dynamically adjust its coding behavior according to the estimated available bandwidth, and optimize the quality of video streams. Simulation using NS-2 demonstrates the effectiveness of the proposed mechanism.
