This paper proposes to leverage multi-source multi-path diversity to design a video streaming system for supporting concurrent video-on-demand (VoD) services over wireless mesh networks (WMNs). By integrating a wireless interference model into consideration, we have a more realistic network model to capture the characteristics of wireless networks. Based on that, we mathematically formulate the route selection problem for the proposed streaming system using rate/interference-distortion optimization framework, and rely on a genetic algorithm to solve it heuristically. Simulation results show that the proposed system has better performance than systems using single-source, single-path and systems that do not consider interference.
