Sequential Geometric Approach for Device-Free Localization with Outlier Link Rejection

Algorithm 2

The process of SGOLR.

(1) Use the Algorithm 1 to detect and eliminate outlier links,

(2) Get the coordinates of the intersections of the effect links,

(3) Use the density of IoL to detect and eliminate the isolated intersections.

(4) Estimate the coordinate of the target according to 12.
