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 optimiza- tion framework to help the system optimally select concurrent streaming paths. We mathematically formulate such a route selec- tion problem, and solve it heuristically using genetic algorithm. Simulation results demonstrate the effectiveness of our proposed scheme.

希克力出生在法国南部一个叫马尔蒂夫的小镇,这里气候干旱,河流稀少,还发生过一起严重的化工厂毒气泄露事故。希克力的母亲就死于这次事故。更可怕的是小镇上流行一种罕见的肺病,接踵死去的人越来越多,而医生一直也没有查清这到底是一种什么肺病和该怎样进行治疗。   1982年春天,希克力的父亲也不幸患上了这种可怕的肺病,经常拼命咳嗽,心虚气短。那年希克力16岁,他不想再失去父亲。然而,医生们几乎都是众口一词,
