A node device 100 is configured to: allocate a channel for communication to each of radio interfaces; between the radio interface and a radio interface which is included by an adjacent node device and to which the same channel as the channel allocated to the radio interface is allocated, establish a communication link using the channels; and, by using a communication link (a use communication link) set for the destination of received data among established communication links, transfer the data to the adjacent node device. The node device 100 specifies an unused channel that is other than a channel used by a communication link set as the use communication link among already allocated channels (101), and releases allocation of the unused channel (102).
