Security issues associated with successful operation of cognitive radio networks (CRNs) recently are gaining a lot of attention. In this paper we focus on a specific class of Denial of Service attack that is executed through Channel Eviction Triggering (CET), whereby the adversary nodes unduly invoke mechanisms inherent in CRN operation to protect the licensed users and thus disrupt secondary access...
In this paper, we present a distributed relay selection and power allocation scheme concurrently considering the channel states of all related links and residual energy state of the relay nodes for cooperative transmission in cognitive radio (CR) networks. Specifically, we formulate the CR network with cooperative transmission as a restless bandit system, which has been widely applied in operations...
