PURPOSE: A node location recognition method in a wireless sensor network and apparatus using the same are provided to recognize a location near by a real node location by using node information. CONSTITUTION: A distance between anchors and a node which is not able to recognize a current location is measured. The size and direction of an acting force is measured. A first prediction node location is calculated(110). The acting force between the anchor and neighbor nodes is measured. A predicted location of a second node is calculated(130). The direction and size of the acting force between the anchor and the node is measured. Errors of the second predicted node location is corrected(150). |
