无线传感器网络定位研究综述

The Survey on Localization of Wireless Sensor Networks

节点定位技术是无线传感器网络的关键技术之一,而定位算法则是定位技术中的核心。在节点定位的过程中,由于节点数目、节点距离以及环境等因素,会对节点的定位精确度造成影响,基于此,提出了各种对定位算法的改进以提高节点定位的精确度。本文基于测距以及非测距两方面介绍了各种节点定位算法,并详细介绍了几种比较经典和新颖的改进方法。

Node localization technology is one of the key technologies in wireless sensor networks,and localization algorithm is the core of localization technology.In the process of node localization,due to the number of nodes,the distance between nodes and the environment and other factors,the accuracy of node location will be affected.Based on this,a variety of improvements to the posi⁃tioning algorithm are proposed to improve the accuracy of node positioning.This paper introduces various node localization algo⁃rithms based on ranging and non ranging,and introduces several improved methods for Centroid Localization Algorithm in detail.
