A Study on Analysis of Attacks and Combating Security Issues in Cognitive Radio Networks

Cognitive radio (CR) is introduced as a solution to improve spectrum utilization by enabling secondary access to licensed spectrum. Discovering spectrum holes is therefore essential. To explore the spectrum opportunities, there are two approaches: spectrum sensing and database-driven. While most examination work in the field of security is based on latent attack detection procedures for example attack detection on signal detection, the goal of this
exploration work is to build up a functioning attack detection based security framework for cognitive radio networks. This examination is extension of SMTD (Security Management based on Trust Determination) protocol proposed. In their seminal work, creators have proposed a functioning attack detection component based on trust determination in grouped cognitive radio network.
