Cognitive radio could satisfy the demand for radio spectrum urgently required by the Internet
of Things employing machine type communication to connect numerous machines. In …

In this paper, we propose a multi-channel full-duplex Medium Access Control (MAC)
protocol for cognitive radio networks (MFDC-MAC). Our design exploits the fact that full …

In this paper, we propose an adaptive medium access control (MAC) protocol for full-duplex
(FD) cognitive radio networks in which FD secondary users (SUs) perform channel …

We consider the Medium Access Control (MAC) protocol design for full-duplex cognitive
radio networks (FDCRNs). Our design exploits the fact that full-duplex (FD) secondary users …

Recently cognitive radio has been proposed to solve the problem of spectrum scarcity with
the help of an opportunistic utilisation of unused spaces in the spectrum. The …

Abstract Machine type communication connecting machines in the Internet of Things (IoT)
brings massive traffic and rapidly increases the demand for radio spectrum in wireless …

Because of the asynchronization between primary and secondary wireless networks, the
synchronization between primary users (PUs) and secondary users (SUs) can be hardly …

Cognitive radio network is an intelligent and adaptive communication technology used to
effectively utilize the radio spectrum to provide better communication. It enables the …

A novel distributed cognitive radio multichannel medium access protocol without common
control channel was proposed. The protocol divided a transmission interval into two parts for …

Enormous growth of wireless applications makes the spectrum scarcity problem worse day
by day. Moreover, traditional fixed spectrum assignment policy causes serious spectrum …
