Abstract:
To address the security problems caused by malicious nodes in wireless sensor networks,in this study, based on the Bayesian trust models,the adaptive reputation maintenance function was introduced to reduce the influence of the previous node and number of interaction,and the abnormal weakening factor was introduced to reduce the false detection of node by the abnormal behaviors caused by network faults,and combined with the fuzzy evaluation mechanism,to calculate direct trust. In order to improve the reliability of recommendation trust evaluation,the similarity measure theory was adopted to assign weight to different recommendation nodes and redistribute to obtain indirect trust. In order to improve the detection accuracy of the trust model,a weighted factor was adopted to determine the size of the comprehensive trust value jointly by variables in direct and indirect trust. Using the adaptive weighting dynamic updating comprehensive trust value,it could effectively avoid the rapid promotion of trust in a short time,and use the sliding time window to predict the comprehensive trust value. The WSN dynamic trust evaluation and prediction model integrating multiple indicators FSEPM was built. The difference between the predicted trust value and the actual trust value was compared with the trust threshold to judge the node property. Simulation results showed that the trust evaluation model could accurately and reliably evaluate the trust relationship between nodes,detect malicious nodes effectively,and improve the security of wireless sensor networks.
