“…This would make the task more challenging and difficult for a cognitive user. In addition, this can affect the performance due to reasons like lower efficiency, slower sharing of spectrum resources allocation, and less reliability than the cooperative technique [8,16,24,33]. The last classification is access technology, whether it is an overlay or underlay approach [22,24,26,34].…”

“…This indicates that the cognitive ability and reconfiguration capability are the core elements that make CR an advanced technology, which grants dynamic access to the unused spectrum for both licensed and unlicensed users through certain characteristics: adoption, awareness, modification, capability of learning, observation, and communication in realistic environments [10][11][12][13][14][15][16]. These characteristics provide reliable communication among CR users anytime and anywhere as a smart and intelligent choice to operate dynamically through artificial intelligence algorithms, such as spectrum sensing, spectrum sharing, and spectrum mobility [13,17].…”

Abstract-Cognitive Radio plays a major part in communication technology by resolving the shortage of the spectrum through usage of dynamic spectrum access and artificial intelligence characteristics. The element of spectrum sharing in cognitive radio is a fundamental approach in utilising free channels. Cooperatively communicating cognitive radio devices use the common control channel of the cognitive radio medium access control to achieve spectrum sharing. Thus, the common control channel and consequently spectrum sharing security are vital to ensuring security in the subsequent data communication among cognitive radio nodes. In addition to well known security problems in wireless networks, cognitive radio networks introduce new classes of security threats and challenges, such as licensed user emulation attacks in spectrum sensing and misbehaviours in the common control channel transactions, which degrade the overall network operation and performance. This review paper briefly presents the known threats and attacks in wireless networks before it looks into the concept of cognitive radio and its main functionality. The paper then mainly focuses on spectrum sharing security and its related challenges. Since spectrum sharing is enabled through usage of the common control channel, more attention is paid to the security of the common control channel by looking into its security threats as well as protection and detection mechanisms. Finally, the pros and cons as well as the comparisons of different CR-specific security mechanisms are presented with some open research issues and challenges.

“…Thereby, user needs to take direct access to the sensor nodes to acquire data whenever he (or she) requires. Research into security and privacy focused on wireless sensor networks has been challenging issues to researchers [6][7][8][9][10][11][12][13][14][15]. Wireless sensor networks are subject to various attacks including eavesdropping, modification, interception, replay, tracking and identity exposure because of their open and dynamic nature.…”

“…CR nodes compete to sense available channels. [3].Providing security is a major issue that comes into picture in any network. In the case of CR networks, selfish attacks are a type of threat, in which the selfish secondary users (SSU) will occupy all or part of the channels and leave those channels underutilized.…”

Cognitive radio (CR) is a promising technology in ad-hoc networks to solve the problems that result from the limited available spectrum and the inefficiency in the spectrum usage by utilizing the existing wireless spectrum advantageously. When the licensed primary user is not using the spectrum, the available channels are allocated for the unlicensed secondary users. An increasing numbers of security threats are being identified when the idea of cognitive radio becomes reality. One such threat is the possible presence of selfish secondary users who try to occupy all available channels. In this paper, an efficient selfish attack detection technique called Distributed Reaction Mechanism is introduced and implemented which results in enhanced detection rate.
