Most Active Band (MAB) Attack and Countermeasures in aCognitive Radio Network
Abstract– Most Active Band (MAB) Attack and Countermeasures in aCognitive Radio Network. This paper investigates a type of attacks on a cognitive radio (CR) network, most active band (MAB) attack, where an attacker or a malicious CR node senses/determines the most active band within a multi-band CR network and targets this band through a denial of service (DoS) attack. We propose a countermeasure strategy, coordinated concealment strategy (CCS), < Final Year Projects > to counter the MAB attack. Our results show that CCS significantly outperforms CR’s inherent capability of signal/interference avoidance under a MAB attack. We also introduce power control in CCS to further improve the countermeasure performance in terms of the percentage of survival nodes.
