摘要：In general, traditional routing paths which are designed for wireless sensor networks are application-agnostic. We are considering an application flow in a wireless sensor networks consists of video traffic. To overcome the problem of video distortion there are many routing metric mechanisms. Popular link-quality-based routing metrics (ETX) do not account for the dependence of video across the links of a path which can cause a video to flow through few paths, thus causing high video distortion. In this paper, we construct an analytical framework model to evaluate the video frame loss process to understand the impact of wireless network not account for the dependence of video across the links of a path, thus causing high on video distortion. This framework allows to minimize the video distortion by formulating a routing policy by accounting the distortions caused by a flow, end-toend by distributing the frames across the paths through priority based. We evaluate via testbed experiments that our protocol is efficient in reducing the video distortion and minimizing the user experience degradation.
