A distance measurement device includes a transceiving unit that, in a distance measurement process between the distance measurement device and nodes, transmits a command to the nodes, and receives a response as a response to the command; and a distance measurement control unit that instructs the transceiving unit to transmit the command when the distance measurement process starts, measures a period of time until the response is received after the command is transmitted, and calculates a distances between the distance measurement device and the nodes on the basis of the measured period of time. The distance measurement control unit determines the number of repetitions for the distance measurement process until the distance is calculated after the command is transmitted on the basis of the calculated distance. |
