ES-Aware: Energy and Stability Support for P2P Video Streaming on Mobile Devices

Peer-to-Peer (P2P) technology has been used as a mean to deliver video streaming services over the Internet. Although mobile devices have been increasingly used to access multimedia content, P2P video streaming applications are still in early stage regarding these devices. The P2P protocol needs to be adapted to meet specific characteristics of mobile devices. In this paper, we propose a novel peer selection approach named Energy and Stability Aware (ES-Aware) which aims to reduce the impact of peers instability and the rapid battery drain. Our approach is implemented in a real P2P video streaming system called RapidStream [4]. Experiments are performed in a Internet-wide environment, PlanetLab [2] integrated with mobile devices, providing a comprehensive and purely experimental methodology to compare different techniques into a P2P video streaming protocol. Results suggest that (i) only the peer connected time is not sufficient as criterion for node stability; (ii) ES-Aware is more effective, saving around 57% of energy, for P2P networks with small percentage of mobile nodes.
