Spectrum sensing, spectrum monitoring, and security in cognitive radios
Spectrum sensing is a key function of cognitive radios and is used to determine whether a primary user is present in the channel or not. In this dissertation, we formulate and solve the generalized likelihood ratio test (GLRT) for spectrum sensing when both primary user transmitter and the …

Security Enhanced Communications in Cognitive Networks
… which will require the communication networks to efficiently manage the increasing complexity. Cognitive network has been envisioned as a new paradigm to address this challenge, which has the capability of reasoning, planning and learning by incorporating cutting edge technologies …

Survivability Against Intelligent Adversary in Next-Generation Wireless Networks
… As a solution, dynamic spectrum access-based Cognitive Radio Network (CRN) has been proposed. CRN allows secondary users (SUs) to use an unused licensed spectrum while the proprietary primary user (PU) is not transmitting. CRN being a next generation wireless network inherits all the …

Security and Performance Engineering of Scalable Cognitive Radio Networks. Sensing, Performance and Security Modelling and Analysis of ’Optimal’ Trade-offs for Detection of Attacks and Congestion Control in Scalable Cognitive Radio Networks
A Cognitive Radio Network (CRN) is a technology that allows unlicensed users to utilise licensed spectrum by detecting an idle band through sensing. How- ever, most research studies on CRNs have been carried out without considering the impact of sensing on the performance and security of CRNs. …

Opportunistic Spectrum Utilization by Cognitive Radio Networks: Challenges and Solutions
Cognitive Radio Network (CRN) is an emerging paradigm that makes use of Dynamic Spectrum Access (DSA) to communicate opportunistically, in the un-licensed Industrial, Scientific and Medical bands or frequency bands otherwise licensed to incumbent users such as TV broadcast. Interest in the …
