【 摘 要 】

Cognitive Radio Networks (CRN) is increasingly becoming an important technology in wireless communication networks because of its potential and ability to improve the utilization of radio spectrum. Such networks implement co-operative spectrum sensing technique to locate vacant bands and apply strategies to decide when, how and in which band they may choose to communicate.  In realizing this, the network is exposed to a major threat known as Primary User Emulation Attack (PUEA), in which malicious users may tend to destruct the spectrum sensing process by imitating the primary user signal and deceive the Secondary Users (SU) from transmitting in the vacant spectral bands. In this article, a new energy detection cooperative spectrum sensing technique in a cognitive radio networks is proposed to assist in the reduction of errors made by secondary users in detecting primary user signals in spectral bands with the presence of a PUEA considered in the network. Comparing our proposed method to other existing PUEA mitigation methods, the results show that our proposed technique can effectively mitigate PUEA in CRNs.
