Wireless Opportunistic Podcasting: Implementation and Design Tradeoffs

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. The authors aim at releasing this limitation and present herein a podcasting system architecture based on opportunistic wireless networking that allows people to extend podcasting to ad hoc domains. The design is explained and presented together with a prototype implementation running on hand-held devices.
