Trust-group Based Resource Allocation Mechanism in Grid Market Enviorment
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.
