【摘要】：曾提出的一些光纤激光网络中被入侵节点定位方法往往定位误差大、能耗高,为此,提出一种基于加权质心定位技术的光纤激光网络中被入侵节点定位方法。所提方法对光纤激光网络的通信情况进行了模拟,并提取其中的网路节点信息进行分析,将光纤激光网络上行通信中的节点设为多节点,下行通信中的节点设为单节点,使用加权质心定位技术,给出单节点定位和多节点定位两种被入侵节点定位方法。单节点定位将光纤激光网络看作一个多边形,多边形的质心坐标便是被入侵节点的定位坐标。多节点定位将光纤激光网络看作一个椭圆形,连接椭圆形边缘上已知坐标的两点,并以此计算出被入侵节点的定位坐标。实验结果表明,所提方法的定位误差较小、能耗较低。
[Abstract]:Some previously proposed localization methods for intruded nodes in optical fiber laser networks are often characterized by large localization errors and high energy consumption. Therefore, a new method based on weighted centroid localization is proposed for the location of intruded nodes in optical fiber laser networks. The proposed method simulates the communication situation of optical fiber laser network, and extracts the network node information for analysis. The nodes in the uplink communication of optical fiber laser network are set as multi-nodes, and the nodes in the downlink communication are set as single nodes. Using weighted centroid localization technique, two kinds of location methods of invading nodes are presented: single node location and multi-node location. The fiber laser network is regarded as a polygon and the centroid coordinate of the polygon is the location coordinate of the invading node. The optical fiber laser network is regarded as an ellipse, connecting two points of the known coordinates on the elliptical edge, and the location coordinates of the invading nodes are calculated. The experimental results show that the positioning error of the proposed method is small and the energy consumption is low.
