摘要/Abstract

摘要： 研究了具有时延和通信拓扑变换的移动传感器网络（MSN）分布式融合估计问题.结合无色信息滤波、自适应一致性算法并考虑通信时延而设计的基于自适应一致性的融合结构，提出了一种名为基于自适应一致性的分布式无色信息滤波（AC_DUIF）的分布式融合估计算法.以空中移动传感器网络跟踪移动目标为例，通过仿真验证了所提算法的性能.仿真结果表明，该方法能够在以分布形式提高网络中各节点对目标位置估计精度的同时，保证节点之间的一致性，并具备对网络通信延时的适应能力.

Abstract: To the problem of distributed estimation for mobile sensor networks（MSN）with communication delays and switching network topologies, a novel distributed fusion estimation algorithm, named adaptive consensus based bistributed unscented information filter（AC_DUIF）, was presented. The proposed algorithm was based on unscented information filter, adaptive consensus algorithm, as well as a new fusion framework for the consideration of the communication delays. An application of target tracking using an air mobile sensor networks with dynamically switched network topologies was employed to illustrate the performance of the proposed algorithm. The simulation results show that the proposed method can significantly improve the accuracy of target position estimation of each sensor node in a distributed fashion, when the distributed consensus between each nodes and the adaptability of the communication delays are assured.

Key words: mobile sensor networks, distributed fusion estimation, unscented information filter, adaptive consensus
