PROJECT TITLE :

A Distortion-Resistant Routing Framework for Video Traffic in Wireless Multihop Networks

ABSTRACT:

Traditional routing metrics designed for wireless networks are application-agnostic. During this paper, we have a tendency to contemplate a wireless network where the applying flows incorporates video traffic. From a user perspective, reducing the level of video distortion is crucial. We ask the query“Should the routing policies change if the end-to-end video distortion is to be minimized?” Popular link-quality-primarily based routing metrics (such as ETX) don't account for dependence (in terms of congestion) across the links of a path; hence, they'll cause video flows to converge onto some paths and, thus, cause high video distortion. To account for the evolution of the video frame loss process, we have a tendency to construct an analytical framework to, initial, perceive and, second, assess the impact of the wireless network on video distortion. The framework permits us to formulate a routing policy for minimizing distortion, based mostly on which we design a protocol for routing video traffic. We realize via simulations and testbed experiments that our protocol is efficient in reducing video distortion and minimizing the user experience degradation.
