Optimized multi-path routing using dual decomposition for wireless video streaming

For video streaming over wireless ad hoc networks, source rate allocation and routing scheme are two important issues. In this paper, we propose a fully distributed algorithm to jointly optimize the source rate and routing scheme. We use dual decomposition to separate the optimization problem into multiple subproblems, which are then solved in parallel. The distributed nature of the proposed algorithm is extremely adequate for wireless ad hoc networks. Simulation results show that the proposed routing scheme outperforms some existing multi-path routing schemes.
