<P>PROBLEM TO BE SOLVED: To safely and certainly carry out communications even if radio wave environment changes in environment where multi path routes become main transmission routes. Ž<P>SOLUTION: Radio wave routes from a radio node to another node and the received power are calculated based on shapes of surrounding structures and location information, which can generate physical phenomena such as reflection, transmission, diffraction, etc. of a radio wave. The method estimates the structures which have an effect on the reflection, the transmission, or the diffraction on the calculated radio wave routes, adjusts the receiving power using the existence probability, and estimates possibility of usage of the radio wave route, and estimates usage possibility of the radio wave route by the received power after adjustment.
