Cognitive Radio (CR) is a recent network paradigm that allows Secondary Users (SUs),
such as, wireless devices/users, to intelligently access portions of the radio spectrum not …

Rapid broadcast of safety message (sm) is critical for real-time applications in cognitive
radio vehicular ad hoc networks (CR-VANETs). The arrival of primary users (PU) and the …

A cognitive radio (CR) network should be able to sense its environment and adapt
communication to utilize the unused licensed spectrum without interfering with licensed …

Cognitive Radio is a promising technology for solving spectrum scarcity problem. Design of
medium access control (MAC) protocols for Cognitive Radio Networks (CRN) is challenging …

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

We propose a novel dynamic common-control-channel-based medium access control
(DCCC-MAC) protocol for cellular (centralized) cognitive radio (CR) networks. Specifically …

Cognitive radio (CR) is a recent innovation based on an intelligent radio design paradigm
that can vastly improve utilization of valuable radio spectrum. However, successful …

Current proposals for Cognitive Radio Networks (CRN) are created mainly to solve dynamic
spectrum access where several cognitive devices are searching for free frequency bands, ie …

With the fast proliferation of low-cost and low-power devices, numerous consumer electronic
devices have been deployed to create consumer home automation networks (CHANs). In …

In wireless ad hoc networks, all nodes have equal right to access the medium. Hence, the
performance of this mode is mostly limited by traffic congestion. To alleviate such a problem …
