Abstract
A method for locating positions of electronic devices is provided. The method includes receiving, by a master electronic device, movement information of the electronic devices, and setting the electronic devices to a first reference device, a second reference device, or a normal electronic device, based on the movement information, calculating, by the first reference device, a distance between the first reference device and the second reference device and a distance between the first reference device and the normal electronic device, calculating, by the second reference device, a distance between the second reference device and the normal electronic device, and transmitting the calculated distance information to the first reference device, and calculating, by the first reference device, a position of the normal electronic device by a triangulation method, based on the distances among the first reference device, the second reference device, and the normal electronic device.
