PROBLEM TO BE SOLVED: To provide a slave radio device that is able to automatically set path information on a routing table and to restrain the number of communication packets in the U-bus air cluster tree system.SOLUTION: A slave radio device comprises: a multi-address packet transmitting unit 11 for transmitting a multi-address packet including the number of hops to a master radio device when in an activated state; a relay station existing slave radio device selecting unit 12 for selecting an existing slave radio device with a fewer hop number as a relay station existing slave radio device; a path construction request transmitting unit 13 for transmitting a path construction request toward the relay station existing slave radio device; a data packet transferring unit 14 for transferring the path construction request toward the master radio device, and for transferring a path construction response toward a new slave radio device; and a path information registering unit 15 for registering the path information on the new slave radio device with its routing table when receiving the path construction response, and for registering the path information to the master radio device with its routing table when receiving the path construction response. |
