Cognitive radios (CRs) have been considered for use in mobile ad hoc networks (MANETs). The area of security in Cognitive Radio MANETs (CR-MANETs) has yet to receive much attention. However, some distinct characteristics of CRs introduce new, non-trivial security risks to CR-MANETs. In this paper, we study spectrum sensing data falsification (SSDF) attacks to CR-MANETs, in which intruders send false...
In cognitive radio networks, secondary users can cooperatively sense the spectrum to detect the presence of primary users. In this paper, we propose a fully distributed and scalable cooperative spectrum sensing scheme based on recent advances in consensus algorithms. In the proposed scheme, the secondary users can maintain coordination based on only local information exchange without a centralized...
Cooperative spectrum sensing is attracting more attention in cognitive radio networks. This paper proposes a fully distributed consensus-based cooperative spectrum sensing scheme to cope with both fixed and random bidirectional connections among secondary users. In the proposed scheme, secondary users can maintain coordination based on only local interactions without a centralized common receiver...
