Abstract: A novel circle fitting algorithm is proposed in this paper. The key points of this paper
are given as follows: (i) it formulates the circle fitting problem into the special source localization
one in wireless sensor networks (WSN); (ii) the multidimensional scaling (MDS) analysis is applied
to the data points, and thus the propagator-like method is proposed to represent the circle
center parameters as the functions of the circle radius; (iii) the virtual source localization model
can be rerepresented as special nonlinear equations of a unique variable (the circle radius) rather
than the original three ones (the circle center and radius), and thus the classical fixed-point
iteration algorithm is applied to determine the radius and the circle center parameters. The
effectiveness of the proposed circle fitting approach is demonstrated using the simulation and
experimental results. © 2013 Junli Liang et al.
