Abstract:
1. A wireless localization method that performs localization by using a plurality of access points at a plurality of sample points having known physical locations that are arranged at regular distances from each other, the wireless localization method comprising: detecting a first sample point, a second sample point, and a third sample point from the plurality of sample points that are most proximate to a predetermined node; calculating corrected coordinates of the predetermined node 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 sample point and second sample point, an RSS value between the first sample point and third sample point, and a distance between the plurality of sample points; and estimating a location of the predetermined node by reflecting the corrected coordinates in relation to the coordinates of the first sample point, wherein the calculating of the corrected coordinates comprises:
