Secure Localization for Primary User Emulation in Cognitive Radio Networks
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.
