In this paper, we consider the time-varying characteristics of practical wireless networks, and propose a joint dynamic rate allocation and transmission scheduling optimization scheme for scalable video multi-rate multicast based on opportunistic routing (OR) and network coding. With OR, the decision of optimal routes for scalable video coding (SVC) layered streaming is integrated into the joint optimization...
This paper aims to optimize the overall video quality and traffic performance for multi-rate video multicast over hybrid wired/wireless networks. In order to perform layered utility maximization over tiered networks, we propose a joint source-network flow optimization scheme where individual layers of the scalable video stream are imposed on their optimal multicast paths and associated rates for the...
