In this paper we present a solution that makes BitTorrent content\ntransfer for mobile device more energy efficient. The main idea of the\nresearch is that instead of downloading the content via BitTorrent\ndirectly to the mobile phone, an intermediate proxy is used which sends\nthe data to the phone in high speed bursts. This results in smaller\nenergy footprint compared with regular BitTorrent data transfer.\nFurthermore, we focus on how the proxy can be hosted on memory limited\nbroadband routers which are available in almost every home. We define an\nanalytical model which can be used to analyze the memory allocation\nstrategies of the proxy peers and predict how proxy peers influence the\nP2P community performance. We verify our model via simulations. We also\npresent measurement results with real life torrents using our prototype\nsystem running on home routers and Symbian based mobile phones.
