As a simple method to simulate a dynamic indoor environment, we investigated a method to calculate the shielding effect of moving objects. In this method, the shielding effect is included in post-processing on the results of ray tracing calculations that does not include objects. The post-processing time of this method depends on the numbers of ray-traced paths. We applied a path clustering method for ray-traced paths in advance to reduce the post-processing time. As a result, the calculation time of the dynamic indoor propagation environment is reduced compared against conventional ray tracing.
