Proposals on the Root Data Domain Gateway and System Operations for IoT Data Interoperability

With the increasing developments in the Internet of Things (IoT), smart-city applications have been attracting widespread interest in many governments, organizations, and companies. The FED4IoT project is a research and innovation project that aims to develop a smart-city application, named “VirIoT,” which realizes the semantic interoperability of IoT data among numerous IoT applications from different grounds. To realize the semantic interoperability of IoT data, data management on cloud platforms, such as FIWARE, is considered necessary. Therefore, the development of a root data domain gateway (RDG), which analyzes IoT data, converts its data format, and posts the data to the cloud service, is required. In this project, Kanazawa Institute of Technology has chosen wildlife monitoring as one of the use cases of the project, and its system using IoT has been designed and developed. Furthermore, its data model has been created for the development of the RDG. Finally, the RDG has been developed as a first step in the semantic interoperability of IoT data.
