Blockchain-Based Platform for IoT Sensor Data Management

The advancement of information technology has significantly improved environmental monitoring by enabling the use of automated devices that measure environmental impact indicators and transmit data through various communication protocols. The water environment monitoring platform is specifically designed to support efficient device management and long-term data storage. The platform targets two types of users: system administrators and end users. End users, consisting of device owners and users with shared permissions to view devices' data, can make identity requests to store data, manage created devices, monitor and track data, and share permission to view any sensors' data on the device with other users. Meanwhile, system administrators verify device creation requests and renew a device's access token. Our platform leverages several technologies, including Blockchain Hyperledger Fabric to store device data, Firebase to store device information and manage users, Nodejs to create server-side APIs that communicate with the Blockchain network, and ReactJS and Reactnative to develop client-side interfaces. The effectiveness of the platform has been evaluated through a series of experiments, and the results show reasonable throughput. These technologies have enabled effective and efficient environmental monitoring and data management in modern agriculture and aquaculture.
