Abstract
In received signal strength (RSS)-based indoor localizations, the localization accuracy of a target node highly depends on the accuracy of estimated distances relative to anchors having a known location. Because RSS measurements are translated into distances by the path loss model (PLM), the accurate and prompt characterization of PLM parameters is crucial for improving the localization performance, especially as the wireless channel environment dynamically varies over time. Here, we propose a zero-configuration method based on inter-anchor measurements in order to accurately characterize PLM parameters with no offline onsite measurements. We then describe and compare two different approaches for converting the RSS measurements to the corresponding distances.
