Abstract

An intrusion detection method which is suitable for the characteristics of WSN (wireless sensor networks) is proposed intrusion detection based on single-class support vector machine. SVM (Support vector machines) can directly train and model the collected data sets, automatically generate detection models, and improve the efficiency of intrusion detection systems. A three-layer intrusion detection model is defined based on this algorithm. The model is more effectively for classifying the data collected by cluster member nodes into intrusion data and normal data. Finally, On the QualNet simulation platform, we implement SVM for the detection of DoS (denial of service) attacks intrusion detection algorithm. The result show that it is feasible to apply SVM to the design of intrusion detection system, with higher system detection rate and lower false alarm rate.
