| 摘 要： | 在P2P文件共享系统中引入激励机制可提高节点共享资源的积极性,从而提高系统的服务能力.由于现有的激励机制存在单点故障,服务效率低下,难以应用等问题,这里提出一种利用市场机制来改善网络可用性的方法,即利用经济学中的价格理论与借贷理论建立一种基于市场机制的激励模型(Dynamic price-based incentive model,DPIM),并给出在分布式网络环境中具体协议的实现.最后,通过计算机仿真,实现了基于市场激励机制和其它激励机制的P2P文件共享系统.结果表明该激励机制充分体现了公平原则,提高了系统的效率和服务质量.

| Abstract: | In P2P file sharing system,incentive mechanisms can increase the positive of sharing resource,thereby enhances the system′s service capabilities.But there are many disadvantages in existing incentive mechanisms,such as single node′s bottleneck,inefficient services,and difficulty to implement.A model is proposed to improve the network availability by using market mechanisms,and named as dynamic price-based incentive model.Finally,some results of simulations are given.These results show that the model fully reflects the principle of equity,increase system efficiency and service quality. |
