A wireless localization method using a fingerprinting technique that performs localization by using a plurality of access points and a plurality of sample points arranged at regular distances, the wireless localization method includes: detecting first through third sample points adjacent to a predetermined node from among the plurality of sample points via the fingerprinting technique; calculating corrected coordinates by using a received signal strength (RSS) between the predetermined node and the first sample point, an RSS value between the predetermined node and the second sample point, an RSS value between the first and second sample points, an RSS value between the first and third sample points, and a distance between the plurality of sample points; and estimating a location of the predetermined node by reflecting the corrected coordinates on coordinates of the first sample point.

Wireless localization method and wireless localization apparatus using fingerprinting technique

Provided is a wireless positioning method using a wireless sensor network, for estimating a position of an unknown node that is a positioning target by using a plurality of anchor nodes arranged at regular intervals, the wireless positioning method including: setting a plurality of test nodes at regular intervals on a space formed by some of the plurality of anchor nodes; obtaining a number and position information of anchor nodes within a predetermined distance from the unknown node; detecting at least one test node matching the obtained number and position information; and estimating a position of the unknown node by calculating an average coordinate value of the detected at least one test node.
