Abstract

Private P2P communities, as known as "BitTorrent Darknets" or "Private Trackers (PTs)", have received much attention in the research community recently. The downloading performance in PTs with high Seeder-to-Leecher Ratio (SLR) is much better than in public P2P communities because PTs deploy auxiliary Share Ratio Enhancement (SRE) mechanism. Nevertheless, though high SLR can benefit leechers, it will result in "Poor Downloading Motivation" problem to members who want to increase their share ratio in order to safely survive. This problem may discourage PT members\´ activity. To improve sustainability of PTs, we adopt Predator-Prey model in ecology to analysis high SLR phenomenon, study the optimal stable SLR range to PTs and solve the above problem. Experiments verify our model and provide insight to study PTs.
