Abstract
(English)
In this paper we concentrate on {em device-free} RSS-based indoor localization methods. These methods, which have generated much research interest in the last few years, are now starting to hit the market. Specifically, the purpose of this paper is to assess the performance improvements of a Variance-based Radio Tomographic Imaging technique, when scanning various radio channels with respect to using only one, the latter being the ``minimum introduced interference'' option. In our setup, the data used for target localization are captured by wireless sensors deployed in the localization area, which are in line of sight among them. The localization error metrics include the mean square error and percentiles of the error distribution
