Demonstrating BooSTER: The broadcast stream transmission epidemic repair

Wireless broadcasting systems, such as Digital Video Broadcasting (DVB), are subject to signal degradation, having an effect on end users´ reception quality. Reception quality can be improved by increasing signal strength, but this comes at a significantly increased energy use and still without guaranteeing error-free reception. BOOSTER is a system for cooperative repair of DVB streams. It operates based on a fully decentralized epidemic algorithm that boosts reception quality by cooperatively repairing lossy packet streams among the community of DVB viewers. In this demo, we demonstrate BOOSTER in a special configurable implementation that allows on-the-fly tweaking of the error rate, network topology, and some protocol parameters, allowing the audience to get a feeling on how they affect end-user experience and load distribution.
