CoCam: A collaborative content sharing framework based on opportunistic P2P networking.

In this paper, we propose CoCam, a framework for mobile phones that enables uncoordinated real-time image and video collaboration between different users sharing the same context, in the same physical location. CoCam addresses the complexity and difficulty introduced when users wish to collaborate, create, and share media contents at the same time. CoCam is based on a middleware that creates a self-organizing ad-hoc network within the context of a shared event in a proximal physical space (a common scene). This middleware automatically handles the context detection, as well as the network configuration and peer discovery. It also enables real-time content sharing while reducing the burden of complicated settings and configurations by the users. As a result of operation tests and user study with the prototype implementation, we have verified that CoCam is feasible and has the potential to enrich the users' experience when sharing contents in an event scenario.
