摘　　要：激励机制是P2P(对等网)中的一个重要的研究课题。P2P这种新的成功模式需要建立一个应用已有成熟的技术的激励机制来实现。本文提出了一种在P2P环境中基于拍卖的激励机制。在P2P所有资源都标以虚拟价格,P2P中节点通过拍卖来决定它获得需要的怎样所应该付出的代价,并用虚拟货币进行支付,而节点通过贡献资源得到虚拟货币。在这种激励机制下,节点可以最大化利用自己的资源,如果P2P每个节点都能够实现资源的最大化利用,我们就可以实现在P2P中自私的节点也愿意贡献自己的资源这一目的。Incentive mechanism in P2P is a important problem. The models of new and successful computing requires the development of appropriate incentive mechanisms that are consistent with the enabling technologies. This paper presents a contingent auction incentive mechanism in P2P environment. All resources are marked price in virtual money, The peers bid for resources in an auction to determine who can get the resources by pay for it with virtual money. The peers can get virtual money through share their resources So the peers＇ maximize their revenue, if every peer maxi- mize their revenue. We achieve the goal that rational and self-interest peers would like to share their resources.
