Abstract: In order to accurately detect abnormal nodes, an industrial internet of things (IIoT) abnormal node detection method based on dynamic trust evaluation algorithm is proposed. Dynamic trust evaluation considers direct trust, recommendation trust, and historical behavioural trust. This evaluation establishes the trustworthiness of each node in the IIoT. Features are extracted from nodes within the positioning range based on their correlations. These features help identify abnormal nodes accurately. Weighted tracking tasks analyse the trust level of each node and collected data to identify anomalies. Detection results are compared with actual outcomes. Test results show accurate node trust evaluation and consistent detection of abnormal nodes. Implementing this method enhances IIoT's security and reliability by efficiently identifying and responding to abnormal nodes.
