Route Stability Techniques for Enhanced Video Delivery on Manets

One of the main problems associated with MANETs is that mobility and the associated route discovery and maintenance procedures of reactive routing protocols cause interruptions on real-time video streams. Some of these interruptions are too large to be concealed using any sort of video technology. In this work we argue that increased bandwidth and QoS strategies do not solve problems associated with mobility. We present a solution for enhanced video transmission that increases route stability by using an improved route discovery process based on the DSR routing protocol, along with traffic splitting algorithms and a preventive route discovery mechanism. We achieve improvements in terms of goodput, and more important, we reduce the video gap durations up to 97% for high mobility scenarios, improving the user viewing experience dramatically.
