Free-Riding in BitTorrent Networks With the Large View Exploit
Overview This paper presents an experimental study on the behavior of BitTorrent networks when selfish peers attempt to maintain high download rates without uploading. This paper modifies a BitTorrent client so that it acquires a larger than normal view of a BitTorrent swarms and connects to all peers in its view. The experimental results show that; the modified free-rider client can achieve better download rates than a compliant client in most common-case public torrents; when the percentage of the modified free-rider clients in PlanetLab-residing torrents with 300 leechers is less than 40%, free-riders on average outperform compliant clients; and as the number of free-riders increases, both free-riders and compliant clients incur substantial performance degradation.
