It makes the existing trust evaluation models inapplicable. To evaluate trust values of nodes and establish trust relationship in nodes, a trust model is proposed on the basis of the analyses of the existing trust models and the minimal principle of uncertainty metric. The model reduces the influence of the non-integrated and unreliable sample space through importing a credible parameter. According to the real situation of networks, the model can minimize the amendment of evaluation values in the whole scope. Contrasted with the evidence-based trust model, the simulation results show that the proposed model is effective. 参考文献 相似文献 引证文献" @default.
