Research on Security Methods of Wireless Sensor Networks Based on Internet of Things Technology

Wireless sensor network operation is an important part of the perception layer of the Internet of Things. However, due to its own physical structure and some characteristics of the use environment, wireless sensor network nodes can easily become the main targets of physical attacks and network attacks. These attacks affect the correctness, reliability and real-time performance of the information transmitted by wireless sensor networks. In this article, we first introduce the characteristics of wireless sensor network technology. We further conducts a security analysis on the network intrusion vulnerability in the wireless sensor network environment. Subsequently, we analyze the main solutions to these attacks. Finally, summarize several issues of wireless sensor network security, and look forward to the key research directions in the future.
