Geometric Buildup Algorithms for Sensor Network Localization

Figure 2

Graphical display of a sensor network with 𝑛=1000,𝑚=100,rd=0.06,nf=0.001. The (blue) diamonds refer to the positions of the anchors; the (green) circles to the original locations of the unknown sensors; the (red) asterisks to their estimated positions by BU. The discrepancies between the original and the estimated points are indicated by the solid lines. RMSD=5.9𝑒−3.
