Detection of PUE- Attack in Cognitive Radio Networks

Abstract

Cognitive Radios (CR) are the radios that are widely used in the wireless networks. It is a software based air interface network . Due to the air interface, the probability of attacks increases. In cognitive radio network, an attack can be defined as an activity that can cause interference to the primary users or licensed users. Primary User Emulation Attack(PUEA) is a major threat to the spectrum. In this paper to prevent from the PUE Attack firstly Distance Ratio Test(DRT) is used which is a transmitter verification procedure based on location verification is used which calculates the received signal strength(RSS) of the signal. Results are compared by plotting False negative ratio(FNR) with measurement and modeling error. Results shows improved value of FNR. Another method that is used is Time difference of arrival(TDOA) and Frequency difference of arrival( FDOA) which helps on determining the location of target. The parameters that are calculated are: time difference of arrival, frequency deviation and direction cosine of target movement. Simulation results were carried out with the help of Graphic User Interface(GUI) through MATLAB. Simulation results in this paper are better from the previous results and achieves high accuracy on transmitter location verification in CR network, which can improve the ability to resist PUE attack.
