The Internet of Things has become a new sensing paradigm for interacting with the physical world. As the sensors in the Internet of Things are often deployed in harsh environments, this makes the sensors prone to failure and malfunctions, producing abnormal and erroneous data, known as outliers. Anomaly detection is critical in the Internet of Things to ensure the quality of data collected by sensors by detecting a high probability of incorrect reads or data corruption. Because the energy of sensor nodes in wireless sensor networks is limited, the transmission between nodes in centralized anomaly detection will consume a lot of energy. Therefore, we propose a distributed anomaly detection method based on a mixture of low precision and high precision to save node energy and improve network life.
