Eyes of the Swarm: Streamers’ Detection in BT

Many BitTorrent (BT) clients are using these BT networks as a video-on-demand service, taking advantage of the popularity and the large collection of media available. However, transforming the swarms into an on-demand media service can cause serious damage to the overall network performance. In this paper, we propose a methodology, using the concepts of Entropy, and present a Spy BitTorrent client that is able to identify peers streaming in a swarm. Large scale monitoring, for real swarms, were performed to detect the presence of streamers.
