Method for determining the coordinates of sensors in wireless sensor networks

摘要

The method of determining the coordinates of individual sensors (elements) in wireless sensor networks based on the range-measurement method is considered, in which the coordinates of the elements are determined by the nonlinear least-squares method, and a regular-adaptive dynamic filtering algorithm is proposed to refine the coordinates for multiple distances measurements. The obtained results allow to increase the accuracy of the estimation and, at the same time, to ensure the stability of the estimation of the coordinates of the elements of the wireless sensor networks.
