Abstract: PURPOSE: A wireless location measuring method is provided to increase location measuring accuracy without respect to distances among transmitting and receiving nodes. CONSTITUTION: A location measuring target node receives a location measuring signal from a reference node to measure a delay tap(S310). The location measuring target node estimates a distance using a delay tap and determines the estimated distance as a temporary estimated distance(S320). The location measuring target node compares the temporary estimated distance with a reference distance(S330). The location measuring target node estimates a final distance using transmission delay if the temporary estimated distance is shorter than the reference distance(S340). The location measuring target node estimates a final distance using delay diffusion if the temporary estimated distance is longer than the reference distance(S350). The location measuring target node calculates the location of the location measuring target node by estimating the distance between at least one reference node and the location measuring target node(S360).
