Optimal Resource Allocation for Video Communication Over Distributed Systems

Many multimedia applications involve real-time video communication over distributed systems, in which there is no centralized controller. Examples of such distributed systems are Peer-To-Peer (P2P) networks, wireless ad hoc networks, and wireless sensor networks. In this paper, the authors provide a review of recent advances on optimal resource allocation for video communication over some major distributed systems including P2P streaming systems, wireless ad hoc networks, and wireless visual sensor networks. In P2P streaming systems, they review the scheduling optimization problem, streaming capacity problem, routing optimization problem, and the prefetching optimization problem.
