| description | The invention discloses an underwater sensor node trust identification method based on an improved variational automatic encoder. The underwater sensor node trust identification method comprises the following steps that: 1, a sink node collects behavior information of each underwater node as a data set; 2, an improved variational automatic encoder VAE is operated, an encoding part learns features of the data and maps the features to a potential space, and a decoding part tries to reconstruct normal data through probability distribution of the potential space; 3, calculating the loss of data reconstruction, evaluating the credibility of the data, and identifying the data with larger loss as abnormal data; 4, adversarial loss is added into reconstruction loss so as to improve the ability of the VAE to capture underwater node data features; and 5, training the improved VAE for identifying the abnormal behavior of the underwater sensor node. The method can effectively improve the accuracy and efficiency of detect |
