PROBLEM TO BE SOLVED: To achieve a radio communication system assuring reliability of communications with a simplified protocol. SOLUTION: A slave node 100-9 conducts measurement to detect whether information is transmitted from the other slave node as the relaying destination for the specified period after transmission of information to the other slave node showing the least number of times of relaying to the master node 300. In the case where information is not transmitted from the other slave node as the relaying destination, the slave node is changed, for retransmission of information, to the other slave node showing the next least number of times of relaying to the master node from candidates of the slave node as the relaying destination based on table.
