Performance analysis of differentiated ARQ scheme for video transmission over wireless networks

The Advance in video coding and wireless communication techniques has enabled video-based services to be the most important component of many emerging multimedia applications. The critical issue is to develop a quality video transmission system over wireless networks. In this paper, an efficient error control scheme, Differentiated Automatic Repeat reQuest (DARQ), is proposed to enhance the robustness of video transmission over error-prone wireless environments. Analytical and simulation results are given to evaluate the performance of the proposed scheme in terms of discard probability, overflow probability and outage probability.
