Large Scale Analysis of BitTorrent Proxy for Green Internet File Sharing

Addressing energy efficiency in P2P services has the potential to make the Internet greener since they comprise a major source of the Internet data traffic. In this paper, we consider approaches for green Internet file sharing. We develop simulation models of proxy-based energy efficient BitTorrent as well as legacy BitTorrent on PeerSim P2P simulator, and explore their characteristics on large-scale scenarios. Our aim is first to identify the operating conditions where proxy-based BitTorrent outperforms the legacy protocol in terms of overall energy efficiency, and then to develop optimizations for the proxy-based approach.
