Claim of US Patent No. 10,560,885

1. A data relay method executed by a wireless communication device to determine whether to relay received data to another wireless communication device and relay and transmit received data to another wireless communication device, the method comprising:when transmitting data, attaching device information identifying another wireless communication device that can establish wireless communication as transmission source neighboring device information to the data, and transmitting the data to another wireless communication device, the device information being stored in a device information storage part included in the wireless communication device;
when receiving data, storing transmission source device information identifying another wireless communication device having transmitted the data into the device information storage part included in the wireless communication device;
when determining whether to relay data, on a basis of a result of comparison between the transmission source neighboring device information attached to the received data and receiver neighboring device information that is the device information stored in the device information storage part of the wireless communication device, determining whether to relay and transmit the received data to another wireless communication device;
when determining whether to relay data, in a case where the transmission source neighboring device information attached to the received data does not agree with the receiver neighboring device information stored in the device information storage part of the wireless communication device, determining to relay and transmit the received data to another wireless communication device; and
when determining whether to relay data, in a case where the receiver neighboring device information stored in the device information storage part of the wireless communication device is a subset of the transmission source neighboring device information attached to the received data, determining not to relay the received data to another wireless communication device and, in a case where the receiver neighboring device information is not the subset, determining to relay and transmit the received data to another wireless communication device.
