Abstract

A Floating Cyber-Physical System (F-CPS) has proposed to promote flexible data utilization by retaining spatio-temporal data, which depends on the location and time of data generation, and the functions (applications) within the specific area. F-CPS is expected to use container technologies to achieve common functionality across many devices. However, because F-CPS also assumes the direct exchange of functions between devices, conventional container technology with large data sizes may hinder data and function distribution within the area. Therefore, F-CPS proposes a compact and versatile application execution platform usingWebAssembly. In this paper, we evaluate its portability through experiments using actual devices. The experimental results show that the data transfer time is reduced by up to 97.7% and the high portability.
