| 摘 要： | INTRODUCTION Wireless mesh networks (WMNs) are ad-hoc networks with full or partial mesh topologies, where nodes can automatically establish and maintain mesh connectivity among themselves. Such a mesh topol- ogy provides each node multiple communication paths to reach its peers. In the presence of link failures caused by, for example, node failures or interference, information can be rerouted through alternative paths to the destination. WMNs have no fixed infrastructure and are easily…

| Abstract: | In this paper, we propose a multi-source multi-path video streaming system for supporting high quality concurrent video-on-demand (VoD) services over wireless mesh networks (WMNs), and leverage forward error correction to enhance the error resilience of the system. By taking wireless interference into consideration, we present a more realistic networking model to capture the characteristics of WMNs and then design a route selection scheme using a joint rate/interference-distortion optimization framework to help the system optimally select concurrent streaming paths. We mathematically formulate such a route selection problem, and solve it heuristically using genetic algorithm. Simulation results demonstrate the effectiveness of our proposed scheme. |
