Patent ID: 8477678

Claim:
A wireless communication device which executes, with use of a wireless signal of a millimeter-wave band, wireless communication with each of a plurality of devices which are present in an ad-hoc network, comprising: a processor; a scan request transmission unit communicatively coupled to the processor, the scan request transmission unit being configured to transmit a scan request to a coordinator being a device that controls the ad-hoc network, the scan request requesting the coordinator to transmit a scan instruction to each of the devices which are controlled by the coordinator, the scan instruction instructing each device to execute a scan process for detecting devices within a communication range; a selection unit communicatively coupled to the processor, the selection unit being configured to receive from the coordinator a result of the scan process which is executed by each of the devices which have received the scan instructions from the coordinator, and to select, on the basis of the received result of the scan process, a device from among the devices, which has a communication range to which at least the wireless communication device belongs; and a coordinator change request unit communicatively coupled to the processor, the coordinator change request unit being configured to transmit from the wireless communication device to the coordinator a coordinator change request for requesting execution of a process for transferring an authority of the coordinator to the selected device, thereby to designate the selected device as a new coordinator of the ad-hoc network.
