A Study on Primary User Emulation Attack in Cognitive Radio Networks
نویسنده
چکیده
CR is an emerging technology in wireless communications. Based on their operating environment CRNs can dynamically reconfigure their characteristcics. So that many security issues has been an alarming fact to CRNs. One such attack is the Primary User Emulation Attack (PUEA). There are many techniques available to mitigate this attack. This paper presents a study about various defense techniques of PUEA and provide better solutions to defend against PUEA.
