Outline of Final Research Achievements

In peer-to-peer (P2P) content distribution, users' nodes, called peers, send received fragments of the original file, i.e., pieces, to others, which can alleviate the server's load. Tit-for-tat (TFT) strategy in game theory can encourage cooperation among peers, i.e., each peer has to provide fragments of the original file, called pieces, to others so as to retrieve its demanding pieces from them. In this study, we reveal that the server's indirect control of P2P content distribution can be achieved by the combination of server's piece sending strategy and TFT constraint among peers.
