摘要
由于网格环境的动态性、复杂性,在节点行为信任度中引入惩罚因子以及资源贡献等参数,以防止协同作弊、恶意推荐和遏制自私节点.利用模糊数学理论,在考虑节点多个因素的基础上,提出一个网格节点信任评估模型,并且给出了网格节点信任度的综合评估算法.该算法可较全面地评估网格节点的信任度.
Because it is dynamical and complex in grid environment, this paper introduces penalty parameter and resources contribution factor and so on in the behavior trustworthiness in order that it prevents the coordination cheats, the evil intention recommends and containment the selfish node. Using the fuzzy mathematics theory and considerating many factors of node, it proposes a trust evaluation model of a grid node, and has produced an integration assessment algorithm of a grid node. This algorithm may comprehensively assess the trustworthiness of the grid node.
