A framework for transmitting video over mobile multi-hop ad-hoc networks

Mobile multi-hop ad-hoc networks are gaining increasing interest as an alternative to infrastructure-based wireless networks. For this to take place, applications running over traditional networks should also be applicable over ad-hoc networks with a reasonable quality. One of the popular applications of networking are streaming multimedia applications. A better support of streaming multimedia applications over ad-hoc networks will speed up the spreading of such networks. In this paper, we present a framework for streaming video over mobile multi-hop ad-hoc networks. The framework is composed of three components handling all problems of video streaming. However, we focus in this paper on the congestion control component, realized through augmented functionality of intermediate nodes. We also present some experimental results with which we tried to identify the causes of the deterioration in quality, when streaming video in a wireless ad-hoc network.
