Abstract

Podcasting has become a very popular and successful Internet service in a short time. This success illustrates the interest for participatory broadcasting, but podcasting is alas only available with fixed infrastructure support to retrieve publicized episodes. We aim at changing this limitation and present herein a system architecture based on opportunistic wireless networking that allows us to extend podcasting to ad hoc domains. The design is explained and presented together with a prototype implementation running on hand-held devices. We analyze different design tradeoffs based on measurements from real devices. The prototype is publicly available and its functionality and performance are intended to be demonstrated in the demo session of this workshop.
