摘　　要：网格市场中可能会存在欺诈节点和自私节点,它们或破坏系统的正常运行,或只消费资源而不提供服务,严重影响了网格市场的正常交易秩序.提出基于信任团体的资源分配机制,源节点根据价格及竞争节点的信誉值及其所在的信任团体的信誉值进行资源分配;为保证源节点有限的资源能够得到有效利用,在竞争节点间进行公平的分配,资源分配时引入了访问控制.分析和仿真实验表明,此种资源分配机制能有效提高交易成功率、资源利用率,提高资源交易双方的收益.There may be malicious nodes and selfish nodes in grid market.Those nodes may disrupt the regular system,or only consume resources but not provider resources,which discreases the performence of the system.This paper presents a resource allocation mechanism based on trust-group （TGRAM） in grid market.Source nodes （resources providers） would take three issues in account when they allocate their resources：resources′ price,trust value of competing nodes （resources consumers）,and trust value of trust group which the competing nodes belong to.To use the source nodes′ resources efficiently and allocate resources fairly among competing nodes,admission control was incorporated in TGRAM,which control the competing nodes′ resources demand according to the trust value of the competing nodes and the number of resources of source nodes.Analysis and simulation results show that TGRAM can improve success-rate of transactions,utilization of resources and improve utilization of the two trade partners.
