【Abstract】Low-power, low-cost, and long-range connectivity for the Industrial Internet of Things (IIoT) networks are the key stipulations, nowadays. However, implementing a cost-effective, flexible, and feasible system considering server and networking security is still an open challenge. In this article, a complete end-to-end long-range wide area network (LoRaWAN) system has been demonstrated by implementing blockchain-based secure distributed data management, which is applicable in various secure IIoT applications. Dynamic data collected by multiple LoRa sensors are encrypted in a LoRa server, and the encrypted content is automatically stored in the InterPlanetary file system (IPFS) to ensure data confidentiality, integrity, and availability. To achieve data consistency, the content IDs collected from the IPFS are stored in the quorum blockchain with consortium setup using a smart contract. The consortium network is maintained by the Raft consensus algorithm employing seven nodes. The design architecture of the hardware used for both LoRa transmitting node and gateway has been described in comprehensive manners. The performance of the LoRaWAN system is analyzed by the received signal strength indicator, the communications range, and packet loss rate metrics in both line-of-sight and nonline-of-sight test systems. The data management scheme is implemented in Python, and the performance is evaluated in terms of transaction time and block size.
