Provided is a communication device which is a node (10) that is subordinate to an aggregation device and that forms a tree-shaped wireless multi-hop network, the communication device comprising: a time management unit (18) for adjusting the time of the device by acquiring time information from the aggregation device or another communication device; a message processing unit (17) that, after the time management unit (18) has adjusted the time of the device, determines on the basis of the time of the adjusted device whether it is necessary to carry out authentication for joining the wireless multi-hop network; and a message transmission unit (13) that, in a case where it was determined that authentication is necessary, transmits the signal required for authentication to an authentication device which determines whether the communication device is a device able to join the wireless multi-hop network. |
