Data Transfer Control Method of Indoor Spatio-Temporal Data Retention in F-CPS

A Floating Cyber Physical System (F-CPS) has been proposed as a region specfic Cyber Physical System (CPS). F-CPS promotes flexible data utilization by retaining Spatio-Temporal Data (STD), which depends on the location and time of data generation, within a specific area. We have proposed a Spatio-Temporal Data Retention System (STD-RS) to deliver STD in the F-CPS. In our previous studies, we assumed that nodes controlled data transmission based on GPS information in outdoor environments. However, F-CPS is also assumed for data retention in indoor environments. In this study, we propose a data transfer control method based on the received signal strength indicator to check its location information without using GPS. Additionally, we conducted experiments in a real environment and demonstrated that the proposed method effectively operates as an STD-RS in indoor environment.
