Intrusion Detection Model Based on Hierarchical Structure in Wireless Sensor Networks

In this paper, presents a intrusion detection model based on hierarchical structure in wireless sensor network. The model structure is simple and improves the security of wireless sensor networks; this model uses a multi-node with the idea of joint collaboration, intrusion detection nodes with anomaly detection algorithm. It shows through experiments with real data that the algorithm can lower the power consumption. This paper first analyzed the main features of the wireless sensor network; then set forth the most common intrusion detection architectures of wireless sensor network; as well as p resented their advantages and disadvantages in detail. And have studied the application of sensor networks to the intrusion detection problem and the related problems. Finally, the paper addressed some valuable directions for further research.
