一种mesh网络的P2P视频资源分配算法

A distribution algorithm of video resource based on P2P in wireless mesh networks

由于无线mesh网络的带宽资源少以及无线信号易受干扰的特点往往导致数据传输时延高及丢包率较高,从而无法满足流媒体业务对流数据的传输时延拥有较高的要求.提出了一个mesh网络的P2P视频资源分配算法,并且分析了移动节点请求视频资源的流行度计算模型.视频服务器通过动态调节mesh路由器存储的视频资源来降低视频数据传输时延.根据实验结果表明,该系统能够有效地降低数据传输时延.

The limited bandwidth resources and the easily interfered wireless signal lead to the packets loss rate in wireless mesh networks so that the need that the streaming media business delivery is not met. This paper proposes a distribution algorithm of video resource based on and analyzes the computing model of video resource populari adjusts the vide resources stored by mesh routers to reduce the can efficiently reduce the delay of data delivery high delay of data delivery and requires the lower delay of data P2P in wireless mesh networks ty requested by mobile nodes. The video server dynamically delay of video data delivery. Through simulation, this approach
