Abstract

To realize local production and consumption of Spatio-temporal data (STD), it is essential to address two key challenges: (1) maintaining data locality by retaining and distributing STD close to their generation area, and (2) enabling application execution on heterogeneous and resource-constrained devices through a lightweight and portable execution platform. To address these challenges, we developed a Floating Cyber-Physical System (F-CPS) that retains both STD and the functions required to process and use the STD within a specific area. In the F-CPS, the STD Retention System directly distributes STD from the generation location and maintains the STD within the target area, thereby ensuring data localization. Furthermore, to facilitate the execution of common applications across heterogeneous devices, we designed a compact and portable application execution platform based on the WebAssembly (Wasm). In this paper, we describe the validation of the feasibility of the F-CPS platform through an integrated experimental evaluation using environmental information. The experiment demonstrated that the F-CPS enables (1) area-based retention of STD and (2) execution of data-processing functions on Wasm containers. The experimental results confirmed that the F-CPS can achieve local production and consumption of environmental data, thereby verifying the effectiveness of this platform.
