Cognitive radio (CR) can successfully deal with the growing demand and scarcity of the
wireless spectrum. To exploit limited spectrum efficiently, CR technology allows unlicensed …

Currently, the radio spectrum is statically allocated and divided between licensed and
unlicensed frequencies. Due to this inflexible policy, some frequency bands are growing in …

Vehicular Ad Hoc Networks (VANETs) have in recent years been viewed as one of the
enabling technologies to provide a wide variety of services, such as vehicle road safety …

In this article, we propose a blockchain verification protocol as a method for enabling and
securing spectrum sharing in moving cognitive radio (CR) networks. The spectrum-sharing …

Cognitive radio (CR) technology is envisaged to solve the problems in wireless networks
resulting from the limited available spectrum and the inefficiency in the spectrum usage by …

Current data networking technology limits a network's ability to adapt, often resulting in sub-
optimal performance. Limited in state, scope, and response mechanisms, the network …

Distributed spectrum sensing (DSS) enables a Cognitive Radio (CR) network to reliably
detect licensed users and avoid causing interference to licensed communications. The data …

In cognitive radio (CR) networks, identifying the available spectrum resource through
spectrum sensing, deciding on the optimal sensing and transmission times, and …

Cognitive Radio (CR) is a promising technology that can alleviate the spectrum shortage
problem by enabling unlicensed users equipped with CRs to coexist with incumbent users in …

Public sector inter-organisational information sharing and interoperability is an area of
increasing concern and intense investment for practice and an area of increasing …
