Abstract
A cognitive radio system has the ability to observe and learn from the environment, adapt to the environmental conditions, and use the radio spectrum more efficiently. These Radios are used all over the world in numerous wireless communication networks due their incredible features and ability to operate dynamically. In last couple of decades, lots of improvements has be done in cognitive radio environment to improve the system and end user experience. Many efficient models and algorithsm were proposed by various researchers for spectrum sensing in cognitive radios. But still there are lots of security threats affecting the network. Many different attacks are performed on the cognitive radio networks which intends to harm the communication causing various problems and issues for the user and the system. In this paper, we review many different security threats and solutions for them based on the Open Systems Interconnection(OSI) layers of the congnitive radio network. Also we discuss about the prevention of network from malicious users and later we express blockchain based security methods for spectrum sensing in cognitive radio network.
