Abstract: Disclosed is a technique capable of effectively estimating a three-dimensional location of a target node through a geometric access by using location information of three anchor nodes. The height of a tetrahedron is calculated. Projected estimated distances, obtained by projecting the estimated distances on a plane H formed by the three anchor nodes, and coordinate values of the three anchor nodes converted on a second coordinate system of the plane H are obtained, and then trilateration is performed using the projected estimated distances and the converted coordinate values so as to calculate an estimated location, projected on the plane H, of the target node. A coordinate value of the calculated estimated location is converted into a coordinate value on a first coordinate system and then the height of the tetrahedron is reflected thereto so as to obtain a coordinate value of the three-dimensional estimated location of the target node.
