Efficient Selfish Attack Detection in Cognitive Radio Network

Attack-Aware Cooperative Spectrum Sensing in Cognitive Radio Networks under Byzantine Attack

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...

Detection of Jamming Attack in Cognitive Radio Networks

Cognitive Radio is becoming a hot research topic in wireless communication field now, which can be used to alleviate the spectrum shortage problem and improve the spectrum utilization. While Cognitive Radio Networks (CRNs) present a promising solution to solve the scarcity of the radio spectrum, they are still susceptible to jamming attacks. The CRN is based on IEEE Wireless Regional Area Netwo...

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...

Enhancing Attack Resilience in Cognitive Radio Networks

Using Fuzzy Logig Approach to Detect Selfish Attacks in Cognitive Radio Network

Cognitive radio play important role in the communication technology by solving shortage of the spectrum bands through the access of „dynamic spectrum access ‟it help for the illegal secondary users to use the more number of license bandwidth. But some malicious attack node can acquire the all spectrum bands of“multiple channels”. avoiding the other nodes from using this channels. “selfish nodes...
