Cognitive radio technology (CR), as a key enabling functionality for the next generation (xG) mobile communication, can remarkably improve the performance of a wireless communication system by being aware of the changes of its surrounding and dynamically modifying its operating parameters to adapt such changes. Recently, the security issues of cognitive radio (CR) networks have drawn more and m...

Cognitive Radio Network (CRN) is an emerging technology used to solve spectrum shortage problems in wireless communications. In CRN, unlicensed secondary users (SUs) and licensed primary (PUs) use resources at the same time by avoiding any interference from SUs. However, sensing process CRN often disturbed a security issue known as Primary User Emulation Attack (PUEA). PUEA one of main issues t...

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...

With the advancement in wireless technology, there is an increasing problem of spectrum scarcity. To resolve this issue, a technology called Cognitive Radio (CR), based on Joseph Mitola’s Software Defined Radio (SDR) was introduced, in which the secondary users can sense the spectrum and utilize the licensed bands when the spectrum is not being utilized by the primary user. Because of its wirel...

The growing cognizance of spectrum scarcity has become a more significant concern in wireless radio communications. Due to the exponential growth data transmission intelligent sensor networks, energy detection promising solution for resolving shortages. Primary user emulation attack (PUEA) been identified as vector cognitive (CR) domain's physical layer. In comparison, CR is method increase eff...

Cognitive radio (CR) technology has been suggested for effective use of spectral resources. Spectrum sensing is one of the main operations of CR users to identify the vacant frequency bands. Cooperative spectrum sensing (CSS) is used to increase the performance of CR networks by providing spatial diversity. The accuracy of spectrum sensing is the most important challenge in the CSS process sinc...

Cognitive radio (CR) is a facilitating technology to efficiently deal with the spectrum scarceness, and it will significantly enhance deployment of upcoming wireless transmission method. Security significant concern, although not well tackle in cognitive networks (CRN). In CR networks, this approach regard as security issue happen from primary user emulation attack (PUEA). A PUEA attacker forwa...

Cognitive radio enabled dynamic spectrum access networks are designed to detect and opportunistically utilize the unused or under-utilized spectrum bands. However, due to the open paradigm of cognitive radio networks and lack of proactive security protocols, the dynamic spectrum access networks are vulnerable to various denial-ofservice (DoS) threats. In this paper, we propose a game theoretic ...
