Secure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks
Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...
متن کاملPrimary User Emulation Detection in Cognitive Radio Networks
Cognitive radios (CRs) have been proposed as a promising solution for improving spectrum utilization via opportunistic spectrum sharing. In a CR network environment, primary (licensed) users have priority over secondary (unlicensed) users when accessing the wireless channel. Thus, if a malicious secondary user exploits this spectrum access etiquette by mimicking the spectral characteristics of ...
متن کاملPrimary User Emulation Attack in Cognitive Radio Networks: A Survey
Cognitive radio is a promising technology aiming to solve the spectrum scarcity problem by allocating the spectrum dynamically to unlicensed users. It uses the free spectrum bands which are not being used by the licensed users without causing interference to the incumbent transmission. So, spectrum sensing is the essential mechanism on which the entire communication depends. If the spectrum sen...
متن کاملA Survey on Primary User Emulation Detection Mechanisms in Cognitive Radio Networks
Cognitive radio is one of the main technologies in the wireless communications. The cognitive radio networks are composed of cognitive, spectrum-agile devices which is able to modify their network configurations according to the spectral environment. This cognitive radio provides the chance reusing portions of the spectrum temporarily for the secondary users. But security is a main issue in the...
متن کاملA Software-defined Radio Prototyping Platform for Cognitive Radio Applications
During the last decades, the demand for higher data rates in wireless communication systems grew steadily. While the number of communication systems increased significantly, the amount of available spectral resources has remained constant. To exploit spectral resources more efficiently, cognitive radio concepts have become of utmost interest. The goal of cognitive radio systems is to sense the ...
