Grid resource selection model based on trust moment

The research on resource selection in grid most focus on QoS property of resource, but the requirement preference of consumer is ignored. Using trust behavior experience in human society, this paper introduced a new concept of trust moment to analyze the trust relationship between transaction partners. Furthermore, trust moment is influenced by multi-factors, such as trust gravitation and trust radius, we use TOPSIS method to implement resource selection based on the requirement preference of consumer. Finally, the effectiveness and feasibility of this model is illustrated by the experiments.
