Cognitive Radio Networks

Cognitive Radio Networks discusses the latest issues of the physical layer, particularly multiple-input and multiple-output antenna design, frequency and pattern reconfigurable antenna design, and orthogonal frequency-division multiplexing scheme.The text covers the challenges of multiple access techniques, such as distributed and centralized design of MAC, time division multiple access, and hybrid schemes for MAC layer design in cognitive radio.1 Covers the CSMA/CA-based CR-MAC design protocol, TDMA-based CR-MAC protocol, and the hybrid MAC protocol. 2 Discusses the concepts related to spectrum sensing, spectrum decision, handoff, and their use cases in cognitive radio networks. 3 Explains the IEEE 802.22 WRAN standardization with details and use of TVWS bands in cognitive radio networks. 4 Explore the Internet of Things (IoT) and cognitive radio integration, and cognitive radio-enabled dynamic network slicing. 5 Showcases the use of technologies such as artificial intelligence and machine learning for cognitive radio networks.
