摘要：
The target tracking problem in three-dimensional wireless sensor networks (3D WSNs) with the consideration of additive and multiplicative noises (AMN) is investigated, which is different from most previous studies. In this paper. Firstly, we put this target tracking problem as an optimization problem by the problem analysis. According to the characteristics of the objective function, both the number of variables and search space of this problem are reduced. Based on a standard Kalman filter, an optimal tracking algorithm is proposed to avoid the instability problem and maximize the tracking accuracy. The advantages of the proposed algorithm are demonstrated via simulation results. © 2015 by Binary Information Press
