A System for Visualizing IoT Device List Based on Captured Frames in Wireless LAN
Yuto Egawa, Yoshiaki Taniguchi, Nobukazu Iguchi · 2019
Among Wi-Fi devices, IoT devices are less managed compared to mobile devices and they are sometimes forgotten that they have been installed. In this paper, we propose and develop an IoT device list display system for supporting management of IoT devices in a wireless LAN. Our system operates on a laptop PC. In our system, based on captured frames in wireless LAN, the list of Wi-Fi devices connected to a specific access point is automatically obtained. Then, the Wi-Fi devices are classified into mobile devices and IoT devices based on information on frame transmission. Finally, the list of IoT devices is displayed to the GUI. Through experimental evaluations, we confirmed that our system can show the list of IoT devices with high accuracy in a wireless LAN composed of up to 20 Wi-Fi devices.
