摘　　要：资源定价策略是网格市场中的一个重要问题,传统的定价策略没有对具有不同信誉的资源消费者提供不同的价格,无法激励交易实体为其他节点提供诚实服务.通过分析资源消费者与资源提供者间的信任关系对定价的影响,提出了一种基于信任团体的差别定价策略.资源消费者分为两类:信任团体内和信任团体外的,资源提供者对两类消费者采用不同的定价方式.由于差别是基于节点间的信任关系的,这就激励节点提供诚实服务.分析和仿真实验表明,差别定价策略能有效提高资源交易成功率、降低节点获得服务需要支付的平均费用.How to price resources is an important problem in the grid market.Traditional price policies can＇t price differently for consumers with different reputation values,thus it has no incentive for users to provide honest services.A differential pricing strategy based on trust group was presented by analyzing the impact of trust relationship between consumer and provider on price strategy.Resource consumers are divided into two categories： nodes in a trust group and nodes out of the trust group.Resource providers charge different types of nodes different prices.Since the differentiation is based on the trust relationship,it encourages nodes to provide trustable information/services.Analysis and simulation results show that the differential pricing strategy can improve the success rate of transactions and reduce the average cost payable by nodes for the services.
