IoT Device State Management System to Inform Defect of Third Party Devices

We are developing an loT platform called InfoFlow. InfoFlow allows users to run loT services in their loT devices without the knowledge of loT and to receive, process, and publish real-time data from devices owned by third parties. However, since loT devices are machines, there is a possibility that an anomaly may occur and the real-time data may fail to be published. As a solution to this problem, there is a concept of network monitoring, which checks for anomalies in the state of devices and surrounding networks. The primary purpose of conventional network monitoring systems is to monitor devices within the scope of individuals or devices within an organization and to notify users when an abnormality occurs. While it is possible to check the status of devices and applications, it isn't easy to implement functions to monitor the status of services running within applications and display the status to third-party devices. This paper proposes a device state management system in InfoFlow. The device state management system will manage user-owned devices and send notifications to users and devices according to the status of the devices they communicate with. The evaluation result shows that the proposed system can send the status of third-party devices without additional hardware and that the time to send the notification is at the tolerance level.
