Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, various Information and Communication Technology (ICT) systems have been developed using wireless communication and are utilized as social infrastructure. Furthermore, CPS (Cyber-Physical Systems) is being utilized to improve the development speed and cost of these ICT systems. CPS enables system development in virtual space by simulating the actual wireless communication environment. Ray tracing methods are frequently used, especially for indoor simulations. Here, in an actual indoor environment, there are moving objects such as moving people and objects. To perform accurate simulations in this environment, it is necessary to reproduce the indoor model at each time and sequentially calculate the influence of dynamic objects on the propagation path, but the amount of calculation is enormous. To reduce this calculation time, our study proposes a method to compensate for the effects of ray shadowing and scattering caused by dynamic objects by utilizing simulation results that only consider indoor stationary objects. For verification, we recreated the environment at a specific time based on an actual indoor radio wave experiment and compared and evaluated the proposed method and a method in which the effects of shadowing and scattering of dynamic objects were calculated using commercial software.
