Layered pre-selection model based on the trust mechanism for web educational resources

Abstract

In order to solve the problem of the credibility on Web educational resources under the current cloud computing platform, we propose a hierarchical pre-selection model of Web educational resources based on trust mechanism. Firstly, a credibility assessment of the Web educational resources was presented. Then the level on pre-selection model by credibility was established. Finally, the resource routing algorithm based on hierarchical pre-selection model was proposed. Simulation results show HPBTA model could ensure that cloud computing Web education resource is availability. In addition, the model provides a solution to pre-selection of cloud computing Web education resources. © 2013 Springer-Verlag.
