| 摘 要： | 在Grid与P2P混合计算环境(Grid&P2P)中,Grid节点提供有QoS保证的服务,而P2P节点的计算资源属于自主贡献资源,不提供QoS保证,用户不为自己的行为承担任何责任,因此节点间的信任关系很难通过传统的信任机制来建立.参考社会学的人际关系信任模型,通过在Grid&P2P中建立信任推荐机制,并利用DS理论对推荐证据进行综合处理来解决该问题.分析及仿真实验说明,基于推荐证据推理的信任模型可以简单有效地解决Grid&P2P中的信任问题.

| Abstract: | Under mixed computing environment of grid and P2P(Grid & P2P), grid nodes provide the service with QoS guarantee However, sharing computing resources of P2P nodes is the user's volunteer action without QoS guarantee The user is not responsible for his actions Therefore it's difficult to establish the trust relationship among users with traditional trust mechanism Referring to social people trust relationship models, a grid & P2P trust model based on recommendation evidence reasoning is designed to solve the problem by building a recommendation mechanism in Grid & P2P and integrating the recommendation evidence with the D-S theory Theoretical analysis and simulations prove that the model can tackle the trust problem under Grid & P2P in a simple and efficient way |
