【摘要】 分布式系统可以被视为一个连接许多代理的网络。在传统的分布式系统中,代理们被假定为是服从性的,即他们遵循一定的算法。但是当许多计算机联结成为一个分布式系统时,系统的各个组成部分会有不同的利益关系。这样的分布式系统就可能是策略性的,即系统的不同部分有自己不同的动因。在一个策略性分布式系统中,策略性代理根据各自的利益作出反应。当每个理性而自私的代理只关心自己的私利时,动因问题就成为一个亟待解决的重要问题。在传统的机制设计中,人们通常只考虑每个用户愿意支付的价格。研究基于服务成本和对用户价值的分布式存储系统中的动因问题,考虑在单个用户、多个存储节点提供服务的场景下,设计相应的机制保证系统在每个节点Selfish的情况下仍能正常运行。更多还原

【Abstract】 Distributed system can be regarded as a network which connects many agents.The agents in traditional distributed system are assumed to be obedient,which means they will act according to the certain algorithm.When many computers connect with each other to form a distributed system,different components in the system might have different benefits relation.And this kind of system can be regarded as strategic,in other words,the components in the system have their own incentive and the strategic agents will react according to their own benefits.The incentive problem becomes extremely important to be resolved when the rational and selfish agents only care about their own benefits.In traditional mechanism design it usually takes the price each costumer is willing to pay into consideration.In this paper,we will focus on the incentive problems based on service cost and value for costumers in P2P storage system.Considering the situation of single costumer and multi-nodes provide the storage service,we will design the corresponding mechanism to assure normal running of the system in consideration of the assumption of selfish of each node.更多还原
