摘要： The present invention relates to a test node-based wireless positioning method and a device thereof, the method comprising the steps of mapping and storing the number and position coordinates of anchor nodes, which are within a set distance from a test node, for each of a plurality of test nodes set at uniform intervals in a space formed by a plurality of anchor nodes; acquiring each position coordinate of the anchor nodes, which are within the set distance from a unknown node to be positioned; comparing each of the acquired position coordinates of the anchor nodes and the position coordinates of the anchor node mapped on the test nodes, so as to select the test nodes of which the number of position coordinates coinciding with the anchor nodes greater than a threshold; and estimating the position of the unknown node by using the position coordinates of the selected test nodes.

摘要： Disclosed is a method for determining an indoor location which includes receiving signals including IDs and information on floors from a plurality of APs that is provided at floors of the multi-story building; measuring reception signal strengths of the received signals, and selecting candidate floors by using the measured reception signal strengths; predicting reception signal strengths of the other candidate floors by using the reception signal strengths of the APs provided at the respective candidate floors; and calculating variance values for the reception signal strengths of the candidate floors, and estimating a current location by using the variance values.
