本文研究了移动的传感器网络中传感器的最优布局和运动协调策略。对于一个目标跟踪应用范围传感器,我们调查的Fisher信息矩阵的行列式,并计算它在2D和3D的情况下,在2D的情况下,全球最小值的特征。我们提出了运动协调算法,引导移动的传感器网络的最佳部署,并服从于一个分散的实施。最后,我们的数值模拟说明了如何提出的算法导致改进的性能的扩展卡尔曼滤波器在目标跟踪的情况下。(c)2006爱思唯尔有限公司保留所有权利。
This work studies optimal sensor placement and motion coordination strategies for mobile sensor networks. For a target-tracking application with range sensors, we investigate the determinant of the Fisher Information Matrix and compute it in the 2D and 3D cases, characterizing the global minima in the 2D case. We propose motion coordination algorithms that steer the mobile sensor network to an optimal deployment and that are amenable to a decentralized implementation. Finally, our numerical simulations illustrate how the proposed algorithms lead to improved performance of an extended Kalman filter in a target-tracking scenario. (c) 2006 Elsevier Ltd.
