Abstract
ABSTRACT In order to improve the communication reliability of wireless sensor networks, a wireless sensor network access authentication system based on embedded microcontroller is designed. Design the overall structure and hardware configuration of wireless sensor network access authentication system, and collect the information of sensor nodes; Creatively based on the duapii protocol, the node trust is calculated according to the node behavior, and the dynamic access authentication of wireless sensor network users is realized through the authentication and login process. According to the system test results, the designed system can realize the access authentication of wireless sensor networks. When the wireless sensor network is attacked by different types of attacks, the communication delay is less than 100 ms, which improves the reliability of network communication.
