Non-transitory computer-readable storage medium, data transfer device, and data transfer method

A data transfer device comprising:

• communication circuitry configured to communicate with a management device, communicate with a sensor via a short-distance radio communication, communicate with each other via short-distance radio communication, and identify present positions;
• and
• a processor coupled the communication circuitry and configured to
• execute a first process that includes storing, in response to reception of identification information of the sensor, sensor information that includes duplicate degrees and position information, the duplicate degrees indicating an amount of computers as transmission sources of inhibit signals received by the first computer, the inhibit signal which inhibits other computers including the first computer from transmitting information of the sensor to the management device, the position information indicating a present position of the first computer;
• execute a second process that includes transmitting the inhibit signal that includes the duplicate degree in the sensor information to a computer among the plural computers that is present in a position to which direct communication via the short-distance radio communication is possible;
• execute a third process that includes storing, in response to reception of the inhibit signal that is output from a second computer as another computer among the plural computers, the duplicate degree that is included in the inhibit signal, associating the duplicate degree with the transmission source of the inhibit signal, and increasing the duplicate degree that is included in the sensor information;
• and
• execute a fourth process that includes transmitting the position information that is included in the sensor information to the management device in a case where the duplicate degree that is included in the sensor information is higher than the duplicate degree that is associated with the transmission source of the inhibit signal.

A data transfer method performed by a first computer among plural computers configured to communicate with a management device, communicate with a sensor via a short-distance radio communication, communicate with each other via short-distance radio communication, and identify present positions, the method comprising:

• executing, by a processor of the first computer, a first process that includes storing, in response to reception of identification information of the sensor, sensor information that includes duplicate degrees and position information, the duplicate degrees indicating an amount of computers as transmission sources of inhibit signals received by the first computer, the inhibit signal which inhibits other computers including the first computer from transmitting information of the sensor to the management device, the position information indicating a present position of the first computer;
• executing, by the processor of the first computer, a second process that includes transmitting the inhibit signal that includes the duplicate degree in the sensor information to a computer among the plural computers that is present in a position to which direct communication via the short-distance radio communication is possible;
• executing, by the processor of the first computer, a third process that includes storing, in response to reception of the inhibit signal that is output from a second computer as another computer among the plural computers, the duplicate degree that is included in the inhibit signal, associating the duplicate degree with the transmission source of the inhibit signal, and increasing the duplicate degree that is included in the sensor information;
• and
• executing, by the processor of the first computer, a fourth process that includes transmitting the position information that is included in the sensor information to the management device in a case where the duplicate degree that is included in the sensor information is higher than the duplicate degree that is associated with the transmission source of the inhibit signal.
