  Abstract

In this work, it is aimed to estimate the location of nodes in a blind area surrounded by walls, where the anchors are located outside of the walls, based on wireless network. First of all, delay of signal caused by walls is mathematically modeled applying the law of refraction. Base on the modeling of delay, this work proposes a simple and novel positioning method that overcomes degradation of positioning accuracy caused by walls. It is noteworthy that the proposed positioning method can perfectly compensate for the degradation. In addition, the performance of the proposed method is analyzed with Wall-dilution-of-precision (W-DoP), which is established in this work. The analysis validates the fact that the proposed method can perfectly compensate for the degradation. Moreover, the analysis implies that W-DoP can be used as a metric for determining arrangement of anchors when there exist walls between tag and anchors. It is remarkable that ranging errors in this work are assumed very rigorously for practical simulation.
