Pervasive Data Access via Opportunistic Communication Links

This research focuses on providing pervasive data access to mobile users without support of cellular or Internet infrastructure. Two mobile users are able to communicate and share data with each other whenever they opportunistically move into the Bluetooth communication range of their Smartphones. We designed and implemented our system on Android-based Smartphones, and deployed our system to students at the Penn State University campus. Our system dynamically captures the interests of mobile users at runtime, and intelligently distribute to users with the data that they are interested in. It also provides unique research facility for investigating the practical interest and data access patterns of users in various types of mobile environments.
