基于信任力矩的网络资源选择模型

提出了基于信任力矩的网格资源选择模型,将网格资源按类型划分为多个可信资源域,每个域的网格资源由其域代理负责组织管理,通过对资源节点进行信任评估,依靠历史交易经验、当前资源属性和个人偏好综合判断,实现了既注重用户资源选择的服务质量,又能满足用户需求偏好的资源选择算法.通过仿真实验验证了模型的可行性和有效性

Model of grid resource selection based on the trust moment

The trust torque was defined as the product of trust gravitation and trust radius and the grid resource selection model based on trust torque was proposed.The grid resources are divided into many trusted resource domains according to different types and the grid resources of each domain are managed by its domain agent.A resource selection algorithm is realized by trust evaluation of resource nodes and comprehensive judgment of historical transaction experiences,cur-rent resource attributes and personal preferences.The algorithm not only pays attention to the service quality of resource selection for users,but also meets the requirements of different users.Simulation results verify the feasibility and effec-tiveness of our model.
