Abstract

Toward the expansion of the digital twin study of wide-area expansion and service cooperation of city OS Yoshihiro NAKAGAWA and Toshihiro KAMEDA We examined wide-area and heterogeneous service cooperation for more efficient data linkage and utilization using a city OS toward the realization of a smart city for society 5.0. We used FIWARE, which is widely used as the city OS. LoRaWAN, one of the LPWA (Low Power Wide Area), was used for wide area coverage. The Things Network, a network of LoRaWAN, was used for examples of service cooperation. This was compared and examined with the case of the MILT Data Platform as another example of other service cooperation. It is necessary to design a flexible conversion method of data structure, commonization, and database arrangement depending on the frequency of access to services.
