Emulation Attack in Cognitive Radio Networks: A study
نویسنده
چکیده
A latest communication technology named “Cognitive Radio Network” is a network in which an un-licensed user can use a freed channel in a spectrum band of licensed user. One of the spectrum management functions is spectrum sensing which the most critical function in the entire communication. If there will be any discrepancy in its functioning then the entire network will be disturbed which would make the network prone to attacks. One such attack is primary User Emulation Attack (PUEA) which dwindle the spectrum access likelihood of proper functioning. The objective of this paper is to give a variety of security requirements for cognitive radio networks and then discusses the PUEA with the preventive procedures to mitigate it.

Cooperative Spectrum Sensing (CSS) is an effective approach to overcome the impact of multi-path fading and shadowing issues. The reliability of CSS can be severely degraded under Byzantine attack, which may be caused by either malfunctioning sensing terminals or malicious nodes. Almost, the previous studies have not analyzed and considered the attack in their models. The present study introduc...
