Designing Systems and Interfaces to Enable Federation of Digital Twins

Digital twin is an emerging technology that allows users to better understand or control the real world by creating a digital world that resembles the real world for their own purposes. Individual digital twin systems are being created in various areas of smart cities, but the need to federate digital twins created by different entities to create complex digital twins is emerging, but not yet. There is still no implemented system for federating a large number of digital twins, which is necessary to show a colorful and spectacular digital twin system. Therefore, in this paper, we design a system and its interface that enables the federation of various digital twin systems.
