Abstract

The invention discloses a WSN abnormity detection method and system based on artificial immunization and k-means clustering. The method comprises that S1) original monitoring data collected by WSN nodes is obtained to form a time sequence, the time sequence is normalized, compression and dimension reduction are carried out on the normalized sequence, and the mean value and variance of each sequential segments in the compressed sequence are calculated; S2) the Euclidean distance between node data and each cluster head is calculated, and an artificial immunization algorithm is used to search an optimal initial cluster head set for K-means classification; S3) whenever new data is distributed into a corresponding cluster, iterative update is carried out on the cluster head value of the cluster till the amount of all data in the cluster does not change; and S4) the WSN determines abnormity according to the amount of data in the cluster in a K-means clustering result. According to the invention, abnormity information in monitoring data can be discovered accurately, the instantaneity and reliability of abnormity event detection of the WSN are improved, and energy and communication bandwidth of the WSN are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a wireless sensor network anomaly detection method and system based on artificial immunity and K-means clustering. Background technique [0002] Wireless Sensor Networks (WSN for short) is the mainstream form of future network development, and has become a new scientific research field in this century. There are many urgent problems that need to be solved at the two levels of basic theory and engineering technology. The wireless sensor network has low cost, low power consumption, and large-scale ad hoc network; the sensor nodes are small in size, battery-powered, and flexible in deployment; and they can adapt to harsh environments where monitoring is difficult for manpower; Monitoring capabilities for disaster prevention. In order to monitor various possible emergencies (such as landslides, air pollution, forest fires, etc.) in time, it is necessary to pay attent...
