Internet of Vehicles (IoV) as an area of research has lately attracted the interest of
researchers for providing safe and comfortable driving experience to users. However …

With growing interest in using cognitive radio (CR) technology in wireless communication
systems for vehicles, it is envisioned that future vehicles will be CR-enabled. This paper …

In cognitive radio (CR) networks, due to the ever increasing traffic demands and the limited
spectrum resources, it is very likely for several secondary networks (SNs) to coexist and …

At present Cognitive Radio Network (CRN) is one of the contemporary research area in
order to improve efficiency as well as improve spectrum utilization factor of wireless …

Cognitive radio network and vehicular ad hoc network (VANET) are recent emerging
concepts in wireless networking. Cognitive radio network obtains knowledge of its …

A cognitive radio ad hoc network (CRAHN) is a group of autonomous users that work in ad
hoc mode. This network enables a secondary user (SU) to use the frequency spectrum …

The spectrum scarcity of VANETs (Vehicular Ad hoc Networks) can be alleviated by
spectrum sharing technology. We present a framework of CCR-VANETs (Cellular-based …

In this letter, the relationship between spectrum sensing time and access delay is analyzed
for a IEEE 802.11-like MAC of a cognitive radio network in which RTS-CTS exchange …

A cognitive radio network has a high promise to improve spectrum utilization, through
exploitation of spectrum holes from the primary network. However, in a distributed …

To increase possible data transmission rate and to provide non-primary user's desired
throughput in short-range communications, in this paper we propose new cognitive radio …
