Research of P2P Offline download based on hybrid P2P network

The Peer-to-peer (P2P) computing has been one of the hottest technologies today, which is popular in distributed file sharing. There are many famous download applications developed such as BitTorrent, Emule, etc. They have been widely studied in terms of network topology, performance and incentive algorithms. Through these kinds of research, many useful functions have been implemented like virtual currency policy which has an incentive effect on free-riders (users who only get resources from others but do not share their own to others in return). In this paper we proposed a new mechanism called P2P Offline download Model. Through providing offline P2P download service, we believe it provides a new way to solve serious problems in real P2P network such as low download speed, huge power cost, etc.
