Peer-to-peer live adaptive video streaming for Information Centric cellular networks

Information Centric Networking (ICN) is a new paradigm in which the network layer provides users with content exposed as names, instead of providing communication channels between hosts. We present a P2P application for the live streaming of video contents encoded at multiple bit-rates. The application enables a limited set of neighboring cellular devices to increase the quality of video playback, by cooperatively using their cellular (e.g. 3G) and proximity (e.g. Wi-Fi Direct) wireless connections. The application exploits key functionalities of ICN: routing by name, in network caching and multicast delivery. We developed a prototype of the application and assessed its performance in a test-bed based on Linux devices with 3G connections, the CCNx tool, the VLC player and the MPEG DASH streaming format. Our main contribution is to show how ICN can provide support to emerging video streaming applications, and ease their creation.
