Abstract
Device-free means targets not carrying any device. Localization and tracking of device-free targets has attracted much attention due to its potential applications where the targets are not cooperative, such as safe guard system. In this paper, we propose a simple Line-Of-Sight (LOS) model and Hierarchical Clustering Filter and Localization algorithm (HCFLA) to localize and track device-free targets. In wireless sensor networks (WSN), the dynamic values of radio signal strength (RSS) between the static environment and the dynamic environment are measured, which are called RSS values in this paper. From the effected links whose RSS value is more than a threshold, the intersections of these links can be calculated. The proposed HCFLA filter the noise points of the intersections and estimate the number and location of targets use with valuable points. Our experimental test-bed is a 4.5 x 4.5 square metres area in indoor environment with 18 Micaz sensor nodes evenly distributed on the edge of the square. The experimental results show that the method can detect the number of the targets in high probability, and localize the targets with average error of 0.23m.
