In this paper,a hierarchical BitTorrent-like file sharing system is proposed to improve the performance of file sharing.Peers in such system are grouped into clusters according to their proximity in the underlying overlay network.A fluid model is developed to compare the proposed hierarchical BitTorrent-like system with the original BitTorrent system.With this model,we find that the hierarchical BitTorrent-like system improves the performance of file sharing quite effectively.Finally,the simulation results further prove that the hierarchical BitTorrent-like system achieves better scalability and efficiency while retaining the robustness and incentives of the original BitTorrent paradigm.
