In order to improve tracking estimation accuracy of square-root unscented Kalman particle filter (SRUKFPF), a new particle filter algorithm of update SRUKF based on iterated measurements is proposed. The algorithm produces the important density function of particle filter using maximum posteriori estimate of iterated square-root unscented Kalman filter, and amends the state covariance using Levenberg-Marquardt...
Accurate, distributed localization algorithms are needed for large scale dense wireless sensor network applications. The Nelder-Mead Simplex Optimization Method (SOM) is applied to solve nondifferentiable problems and can often handle high discontinuity, particularly if it does not occur near the solution. This article proposes a distributed iterative multilateral algorithm. It formulates a function...
In many applications of wireless sensor networks, location is very important data. Location data can come from manual setting or GPS device. However, manual setting requires huge cost of human time, and GPS setting requires expensive device cost. Both approaches are not applicable to localization task of large scale wireless sensor networks. In this paper, we propose an accurate and efficient localization...
