一种新的传感器网络分布式定位方法

A New Distributed Localization Method for Sensor Networks

Yingfei Diao, Zhiyun Lin, Minyue Fu, Huanshui Zhang

摘要:

本文研究了在大型传感器网络中仅使用相对距离测量来确定传感器位置的问题。我们的工作来自Khan等人的开创性论文。[1]其中使用重心坐标给出了用于传感器定位的分布式算法,称为DIRECT。DIMENSIONAL算法的主要限制是所有传感器节点必须在锚节点的凸包内。在本文中,我们考虑了一般的传感器网络没有凸包假设,这在确定重心坐标的符号模式带来的挑战。一个标准的开发,以解决这个问题的基础上可用的距离测量。此外,提出了一种新的分布式算法,以保证所有可定位的传感器节点的渐近定位。

英文摘要:

This paper studies the problem of determining the sensor locations in a large sensor network using relative distance (range) measurements only. Our work follows from a seminal paper by Khan et al. [1] where a distributed algorithm, known as DILOC, for sensor localization is given using the barycentric coordinate. A main limitation of the DILOC algorithm is that all sensor nodes must be inside the convex hull of the anchor nodes. In this paper, we consider a general sensor network without the convex hull assumption, which incurs challenges in determining the sign pattern of the barycentric coordinate. A criterion is developed to address this issue based on available distance measurements. Also, a new distributed algorithm is proposed to guarantee the asymptotic localization of all localizable sensor nodes.
