PROBLEM TO BE SOLVED: To provide a method by which a communication path in a wireless network system can efficiently be decided. SOLUTION: This method adopts a direct retrieval where a master station 0 conducts polling to retrieve slave stations 1, 2 and 5 in existence around itself on the basis of a response including a reception level with respect to the polling and an indirect retrieval where the master station 0 allows the retrieved slave stations 1, 2 and 5 to make polling to slave stations 3, 4 and 6 in existence around the slave stations 1, 2 and 5 and allows the retrieved slave stations 1, 2 and 5 to retrieve the slave stations 3, 4 and 6 on the basis of the response including the reception level with respect to the polling, and the master station 0 creates a table including the propriety of communication among the slave stations and reception levels when the communication is available on the basis of the results of the direct retrieval and the indirect retrieval and decides communication paths on the basis of the table. |
