Analyzing and modeling BitTorrent: A game theory approach

Abstract

Although BitTorrent is gaining popularity and continuous usage as a file sharing system, it is bedeviled with some challenges. Developers and researchers alike are exerting efforts to address such challenges. Free riders exploitation of BitTorrent is a widely acknowledged problem. In particular, free riders misuse BitTorrent through both optimistic and regular unchoke. In this article, we use game theory to model the BitTorrent choking algorithm and conduct extensive performance evaluation experiments to assess its performance as compared with the original BitTorrent choking algorithm.
