Primary user emulation attack analysis on cognitive radio

Abstract

Objectives: For dynamic spectrum sharing and for spectrum scarcity problem solution, Cognitive radio is used. This paper provides Primary User Emulation Attack analysis on Cognitive radio. Methods: This paper presents simulation framework to evaluate the impact of Primary User Emulation Attack on Cognitive radio network. For evaluation of the capability analysis of Cognitive radio networks under Primary User Emulation Attack, a hypothesis test at secondary user based on measured Probability density function of power received has been conducted. Simulation is done with MATLAB 2012b. Findings: For Primary User Emulation Attack analysis on Cognitive radio, the simulation results based on probabilities of miss detection as well as false alarm have been shown. The conclusion is that with increased number of malicious users within the system, false alarm probability also increases. Application: These results are useful for Primary User Emulation Attack analysis on Cognitive radio and are also useful to telecom operators.
