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 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 کاملInvestigation of Primary User Emulation Attack in Cognitive Radio Networks
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...

متن کاملA Primary User Emulation Attack Countermeasure Strategy and Energy-Efficiency Analysis in Cognitive Radio Networks
Due to the fact that security and energy efficiency are investigated separately in the conventional Primary User Emulation Attack (PUEA) countermeasure strategy in Cooperative Spectrum Sensing (CSS) process, the tradeoff between security and energy efficiency is discussed in this paper. CSS can improve detection performance whereas energy consumption will dramatically boost up with the increasi...
