U-Hopper: User-centric heteogeneous opportunistic middleware

This demonstration presents U-Hopper, a user-centric heterogeneous opportunistic middleware specifically tailored to the diffusion of user centric information, such as contextual and entertainment data, in opportunistic environments. The proposed platform exploits proximity wireless interfaces available on most commercial mobile devices for disseminating data among mobile users. Such diffusion if driven by the specific interests of mobile users, combined with the intrinsic locality of data being generated in such pervasive environments. The prototype is developed over java-enabled smartphones and relies on Bluetooth connectivity for achieving proximity communications. In this paper, U-Hopper is described in all its functional components, together with the details of its software implementation.
