The Internet of Things (IoT) is an emerging paradigm that enables many beneficial and
prospective application areas, such as smart metering, smart homes, smart industries, and …

Cognitive radio technologies enable users to opportunistically access unused licensed
spectrum and are viewed as a promising way to deal with the current spectrum crisis. Over …

Channel rendezvous is a vital step to form a cognitive radio network (CRN). It is intractable
to guarantee rendezvous for secondary users (SUs) within a short finite time in …

In this letter, a homogeneous multi-radio channel-hopping (CH) rendezvous algorithm that is
backward compatible with any number of radios for cognitive radio networks is proposed …

The fifth generation mobile communication networks are conceived to provide high date
rates, spectral efficiency, low latency, and energy consumption, as well as better quality of …

Cognitive radio network (CRN) is a promising solution to spectrum scarcity that uses the
dynamic spectrum access mechanism to increase the efficiency of the underutilized licensed …

Cognitive radio networks enable unlicensed users to communicate using the licensed
spectrum without causing interference to legitimate users. To establish a communication …

Irregular spectrum usage and spectrum scarcity in emergency situations is a common
problem in industrial wireless networks. To enhance the dynamic spectrum usage, cognitive …

In this paper, we propose a fast rendezvous algorithm for a heterogeneous cognitive radio
network (CRN), where each user might have more than one radio. One of the well-known …

In cognitive radio networks (CRNs), secondary users can utilize the temporary unused
spectrum opportunistically without affecting the quality of services of the licensed users, also …
