Static positioning using UWB range measurements

• The performance of several existing and partly new algorithms for positioningof sensor node based on distance estimate is compared when the distanceestimates are obtained from a measurement campaign. The distance estimates arebased on time-of-arrival measurements done by ultrawideband devices in an indooroffice environment. Two different positioning techniques are compared: statisticaland geometrical. In statistical category, distributed weighted-multidimensional scaling(dwMDS), least squares, and sum product algorithm are evaluated and in geometricaltechnique projections approach and outer approximation (OA) method areinvestigated. No method shows the best performance in all cases, while in many situations,sum product algorithm, dwMDS, nonlinear least square, projection approach,OA, and weighted least square work well.
