HyCloud: A system for device-to-device content distribution controlled by the cloud

The exponential growing demand of mobile Internet data traffic requires a rethinking of current infrastructures and calls for innovative approaches that provide online-streaming of content to interested subscribed mobile users. We introduce a mobile system called HyCloud for device-to-device content distribution. HyCloud delivers the content from a cloud backend, and it can reduce the total amount of data transferred through the cellular network by exploiting the similarity of interests among multiple mobile users. Our preliminary real-life experiment with video streaming with a simple content scheduler shows that the system can save in average 24% (and up to 38%) of data downloaded by the cellular connection.
