Content Distribution via Internet has become increasingly popular right now. Compared with centralized file distribution system using FTP and HTTP protocols, P2P (Peer to Peer) is more cost-effective. Furthermore, it could help save on bandwidth costs and to handle pick demands. Among many P2P protocols, BitTorrent is one of the most popular protocols right now. The BitTorrent network uses tit-for-tat as a method of seeking Pareto efficiency. However, seeders who contribute more to BitTorrent network than leechers are not incentivized to stay online and upload to others. This paper discusses an incentive mechanism which rewards seeder, who stays in a BitTorrent network and uploads to other peers, with better download speed in its further download process. Experimental results with the incentive mechanism and an analysis of the result are also discussed in this paper.
