摘要:
云计算以服务的方式向用户提供资源,而随着用户需求的日益复杂,一个云服务提供商可能无法独立满足用户的请求,需要选择合适的云服务提供商进行合作.本文从可信的角度,首先分析论证了云服务提供商的历史评分服从狄利克雷分布; 然后考虑到信任关系具有累积性,即便相同的评分也可能会有不同的累积效应,因此根据历史评分本身和历史评分之间的关系研究评分的累积效应并建立狄利克雷分布,并利用该分布计算云服务提供商的信任值和稳定性; 最终基于信任值和稳定性提出一个云服务提供商选择算法并构建基于可信机制的云服务提供商选择(TSCP)模
Abstract:
Cloud computing provides users with resources as a service.With requirements of users increasingly complex,only one service provider may not be able to provide required resources.So it needs to choose an appropriate service provider as a partner.From a trust perspective,we first analyse and apprase history score of the cloud service provider subject to the Dirichlet distribution,then take into account the accumulates of trust relationship.We not only use the interaction scores itself,but also the relationship between the interaction scores to computer the trust value and stable value of cloud service providers,then we build a selecting model based on trust for cloud service providers.Ultimately they provide the basis for the choice of suitable partners.The experiments show that the model in this article is valid to some extent.
