Peer-To-Peer (P2P) and location-based mobile applications have long been an important focus of the ubiquitous computing community. A few recent indicative applications include Color which allows a user to share photos with others in their vicinity, and Cisco StadiumVision which delivers location-based content and service for sports venues. The proliferation of such applications requires power-efficient and overhead-free mobile broadcasting technologies. In this paper, the authors exploit the FM radio that is increasingly available on mobile devices to provide a data broadcasting system for P2P and location-based applications.
