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.
