Time-critical and delay-sensitive multimedia applications require more spectrum and
transmission resources. With the provision of cognitive radios (CRs), the underutilized …

Industrial wireless sensor networks (IWSNs) have to contend with environments that are
usually harsh and time-varying. Industrial wireless technology, such as WirelessHART and …

In this paper, the hybrid interweave/underlay channel access mode is studied for an energy
harvesting (EH) cognitive radio network with multi-class secondary users (SUs). The hybrid …

In this paper, we study vehicular communications (VCs) at road intersections. We investigate
three transmission schemes: direct transmissions (DT), relay transmissions (RT) and hybrid …

In vehicular networks, information dissemination/sharing among vehicles is of salient
importance. Although diverse mechanisms have been proposed in the existing literature, the …

An increasing number of mobile users (MUs) share common interests in general information,
such as traffic information, weather forecast, and domestic/international news. However, the …

The cognitive radio (CR) paradigm has the potential of improving the exploitation of the
electromagnetic spectrum by detecting instantaneously unoccupied spectrum slots allocated …

The enormous developments in the field of wireless communication technologies have
made the unlicensed spectrum bands crowded, resulting uncontrolled interference to the …

Abstract Activating Wireless Power Transfer (WPT) in Radio-Frequency (RF) to provide on-
demand energy supply to widely deployed Internet of Everything devices is a key to the next …

To support delay-sensitive traffic in multi-channel cognitive radio systems, designing a
channel access scheme faces two major challenges, namely, the long waiting time due to …
