光纤激光网络中的被入侵节点定位方法研究

Optical fiber laser in the network intrusion node localization method research

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。

Has proposed some optical fiber lasers were invaded node in the network location methods often have positioning error, high energy consumption, therefore, put forward a kind of optical fiber laser based on weighted centroid localizatiofi in the network intrusion node positioning method. Proposed method for optical fiber laser network communication situation is simulated, and extract the information network node were analyzed, and the optical fiber la- ser network for the node upward communication, downward communication nodes in the set to single node, using the weighted centroid localization technology, orientation and many single node positioning two intrusion node positioning method. Single node localization of fiber laser network as a polygon, polygon centroid coordinates is invaded node location coordinates. Node positioning optical fiber laser network as an oval, connect the oval on the edge of the known coordinates of two points, and thus calculate the invaded node location coordinates. The experimental results show that the proposed method of positioning error smaller, lower energy consumption.
