摘要
传统光纤传感器网络节点安全定位方法成本高、功耗大、扩展性差,在处理大量节点数据信息时误差率高,有时甚至无法实现对光纤传感器网络节点的定位,提出基于粗糙集的光纤传感器网络节点安全定位方法,首先建立未知光纤传感器网络节点信号和数据信息的数学模型,然后运用粗糙集理论对数据进行分析、预处理和约简,最后利用少量信标节点对未知节点测距,实现对光纤传感器网络节点的安全定位。结果表明,该方法可以有效地控制功耗、提高节点覆盖率、准确地实现对光纤传感器网络节点的安全定位。
Traditional optical fiber sensor network secure node positioning method is high cost, high power consumption and expansion of poor, high rate of error in processing a lot of data information of nodes, sometimes it even can not he achieved on the optical fiber sensor network node positioning proposed based on rough set of optical fiber sensor network node safe positioning method. First of all, to establish the mathematical model of unknown optical fiber sensor network node signal and data information, and then use the rough set theory for data analysis, pretreatment and reduction, finally, using a small amount of beacon nodes of the unknown node location, to achieve safe positioning of optical fiber sensor network node. The results show that the method can effectively control the power consumption, improve the coverage rate of nodes, and accurately realize the secure location of the nodes in the optical fiber sensor network.
