Wireless positioning method and apparatus using wireless sensor network

A wireless positioning apparatus 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 apparatus comprising:

• a test node setter for setting a plurality of test nodes at regular intervals on a space formed by some of the plurality of anchor nodes;
• an anchor node information obtainer for obtaining a number and position information of anchor nodes within a predetermined distance from the unknown node;
• a test node information detector for detecting at least one test node matching the obtained number and position information of anchor nodes;
• and
• a position estimator for estimating a position of the unknown node by calculating an average coordinate value of the detected at least one test node.
