The direct trust values in traditional trust models are obtained based on Bayesian theory. In this paper, the direct trust calculation includes two modules: acquiring the node history data module and calculating direct trust value module. The server obtains the historical access record data associated with the target node from the database, such as access duration, access frequency, and energy consumption. The main trust factors will be determined to participate in the final direct trust evaluation. The current trust value of the target node is obtained, which is noted as the direct trust value. |
