Abstract: The present invention relates to a wireless location determination method using a fingerprinting technique and a device thereof. According to the present invention, the wireless location determination method using the fingerprinting technique which performs the location determination using a plurality of access points and a plurality of sample points arranged at regular intervals comprises a step of detecting first to third sample points which are adjacent to an arbitrary node among the plurality of sample points through the fingerprinting technique; a step of calculating a correction coordinate using an RSS value between the arbitrary node and the first sample point, an RSS value between the arbitrary 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 sample points; and a step of estimating the position of the arbitrary node by reflecting the correction coordinate on a coordinate of the first sample point. According to the present invention, the position of the arbitrary node can be accurately estimated using the fingerprinting technique based on RSS and a frequency can be effectively allocated based on an area of the estimated position information. Also, the directivity of the arbitrary node can be estimated using a location determination technique which uses an RSS vector value ratio of the sample points. Therefore, a computation amount can be reduced and high-precision position information can be provided.

Abstract: The present invention provides a wireless positioning method using a wireless sensor network and an apparatus thereof. The wireless positioning method of estimating the position of a random node which is a positioning target by using a plurality of anchor nodes arranged in a constant interval, includes the steps of: setting a plurality of test nodes in a uniform interval on a space formed by partial anchor nodes among a plurality of anchor nodes; acquiring position information and the number of anchor nodes existing within a constant distance from the random node; detecting at least one test node having equal number and position information of the acquired anchor node; and estimating the position of the random node by calculating an average coordinate value of the detected test node. According to the wireless positioning method using the wireless sensor network and the apparatus thereof, average position error of the whole area can be reduced by being able to estimate the position of the random node around the edge and the corner of the wireless sensor network accurately, differently from the case using the conventional WCL algorithm.
