Afaf Mousa, Jamal Bentahar, Omar Alam

Abstract: Highlights•We introduce a novel trust model of IoT services considering dynamic environments.•We define a subjective, objective, collusion resistant and bootstrapped trust model.•We use the log score and error estimation to assess the model’s prediction accuracy.•We use the ROC curves to measure the accuracy of the bootstrapping trust mechanism.•We employ real dataset to show the performance and efficiency of the proposed model.
