对等网络中一种新的激励机制研究

A Novel Incentive Mechanism in P2P Networks

针对对等网络中的搭便车问题,提出了一种可监测调控的激励机制。按网络中搭便车节点的数量分为3个等级,在不同等级情况下使用不同的激励策略。提出了一种基于带宽分配的惩罚策略。仿真实验表明,该激励机制不仅体现了节点享受服务的公平性,提高了下载成功率,而且保护了开发者的经济利益。

For the free-rider problem in peer-to-peer networks,proposes an incentive mechanism of monitoring control.According to the number of free-rider nodes in networks,divides it into three grades and uses different tactics at each grade.Proposes a penalty strategy based on bandwidth allocation.Simulation results show that the incentive mechanism not only reflects the fairness of node services and improves the success rate of downloads,but also protect the economic interests of developers.
