Bayesian Network-based Grid QoS Trustworthiness Evaluation Method
HU Zhou-jun · Jisuanji gongcheng · 2009
To provide trust-enhanced service selection, a Bayesian network-based approach is presented to evaluate the trustworthiness of grid service.The approach employs performance history to construct an evaluation model, which ranks the services in terms of their trustworthiness of Quality of Service(QoS) information and considers degree of consistency in QoS provision.Experimental result shows that the proposed approach can effectively enhance trustworthiness of service information and improve feasibility of service selection.
