Floating Content: Information Sharing in Urban Areas
Content sharing using personal web pages, blogs, or online social networks is a common means for people to maintain contact with their friends, colleagues, and acquaintances. While such means are essential to overcome distances, using infrastructure services for location-based services may not be desirable. In this paper, the authors analyze a fully distributed variant of an ephemeral content sharing service, solely dependent on the mobile devices in the vicinity using principles of opportunistic networking. The net result is a best effort service for floating content in which: information dissemination is geographically limited; the lifetime and spreading of information depends on interested nodes being available; content can only be created and distributed locally; and content can only be added, but not explicitly deleted.
