Research On Intrusion Detection Method In Wireless Sensor Networks

With the rapid development and application of wireless sensor networks, applications in the field of national defense, environmental monitoring, traffic management and forest protection and a wide range of sensor network security issues have become increasingly prominent. Intrusion detection method for wireless sensor network security research is an important area. Study and propose a line sensor network intrusion detection method is very important in theoretical and practical significance.First studied the characteristics of wireless sensor network; Respectively from the physical layer, data link layer and network layer, respectively, the invasion of the wireless sensor network behavior are analyzed in detail; And the three typical intrusion detection model is researched and compared.Secondly from the energy consumption of wireless sensor network are faced with the problem and the intrusion detection performance problems, study a intrusion detection model based on clustering in wireless sensor network, from the node information collection, information processing and intrusion response expounds in three stages, and according to energy consumption problem and intrusion detection performance problems put forward the corresponding solutions. Then study the clustering wireless sensor network intrusion detection model are analyzed in simulation and experiment results, the experiment environment, experimental method and experimental results are analyzed.The tests used in this article are randomly generated intrusion signal that attack the wireless sensor network, and after the intrusion signal received at the receiving end, the receiving end is interested in receiving the signal for analysis. Transmission signals and the intrusion signals are useful experiments, respectively, with a different carrier modulation. Depending on the carrier frequency to detect an intrusion signal at the receiving end.Ultimately, a summary of the thesis research to clarify the direction of future research. This study showed that the wireless sensor network intrusion detection method has a good practical value.
