摘要
针对认知无线电网络中出现的模仿主用户攻击问题，提出对信号源位置进行三维定位的识别方法。在Chan定位算法的基础上推导了Chan定位算法的三维形式。本算法利用接收信号的传播延时，三次使用加权最小二乘法，通过迭代计算最终得到位置估计。实验仿真结果表明，该算法性能良好，可以有效地解决模仿主用户攻击问题。
Abstract
To solve the threat to the primary user emulation in cognitive radio networks, secure localization is proposed as a security scheme based on three-dimensional positioning of the signal source location. Chan Location Algorithm is expanded into three-dimensional form and the signal propagation time is used to estimate the source location with the weighted least square iteratively. The simulation results show that this method has good performance and can effectively solve primary user emulation in cognitive radio networks.
