Spectrum sharing in cognitive radio networks
… bands is quite low. In recent years, Cognitive radio has emerged as a promising solution to increase spectrum occupancy and tackle spectrum scarcity. Cognitive radio enables the unlicensed (secondary) user to establish a communication link in licensed spectrum on the condition that there is no …

Spectrum Sensing in Cognitive Radio Networks
Given the ever-growing demand for radio spectrum, cognitive radio has recently emerged as an attractive wireless communication technology. This dissertation is concerned with developing spectrum sensing algorithms in cognitive radio networks where a single or multiple cognitive radios (CRs) assist …

Bounds on contention management in radio networks
… the contention management issue in wireless networks; it assumes that processes are provided messages, one by one, that must be delivered to their neighbors. We study this problem in two theoretical models of wireless networks, the classical radio network model and its more recent …

Medium Access Control in Cognitive Radio Networks
Cognitive radio (CR) is seen as one of the enabling technologies for realizing a new regulatory spectrum management paradigm, viz. opportunistic spectrum sharing (OSS). In the OSS paradigm, unlicensed users (a.k.a. secondary users) opportunistically operate in fallow licensed spectrum on a …

Enhancing Attack Resilience in Cognitive Radio Networks
… in the overcrowding of those bands. Cognitive radio (CR) is a new technology that enables an unlicensed user to coexist with incumbent users in licensed spectrum bands without inducing interference to incumbent communications. This technology can significantly alleviate the spectrum shortage …

Adaptive Protocols for Frequency-Hop Packet Radio Networks
… data distribution within spread-spectrum packet radio networks requires good performance from the network protocols. This thesis describes research in transmission, forwarding, and routing protocols that are adaptive and decentralized. The protocols are designed specifically for frequency-hop …

Towards realisation of spectrum sharing of cognitive radio networks
Cognitive radio networks (CRN) have emerged as a promising solution to spectrum shortcoming, thanks to Professor Mitola who coined Cognitive Radios. To enable efficient communications, CRNs need to avoid interference to both Primary (licensee) Users (PUs), and among themselves (called …

Resource management of cognitive radio networks with optimization methods.
The deployment of cognitive radio networks provides a promising future for wireless communications with higher spectrum efficiency. A cognitive radio transceiver senses its environment and dynamically adapts its transmission methods and the channel usage so that the induced interference to the …

Multi-Slot Cooperative Spectrum Sensing for Cognitive Radio Networks
A key challenge with current radio access technologies and a consideration in the implementation of next generation radio access networks is limited spectrum availability. Current mobile technologies have been standardized to operate within reserved, dedicated frequency bands. Network operators are …
