Abstract

Free riding, the behavior of attempting to benefit resources contributed by others while sharing their own values as minimum as possible, is one of the key problems in many P2P systems Incentive mechanisms are proposed to solve the problem In this paper, we introduce an all-pay auction model to study the resource distribution process in BitTorrent-like P2P system Based on this model, the advantages and disadvantages of original BitTorrent incentives are presented To improve the BitTorrent system-wide performance, we propose a price differentiation all-pay auction based incentive mechanism considering the long-term share ratio and the short-term predicted upload bandwidth comprehensively Our simulation results verify the effectiveness of the new incentive mechanism to prevent free-riders and strategic peers.
