As the novel and effective approach to improving the utilization of the precious radio
spectrum, cognitive radio technology is the key to realize the dynamic spectrum access …

In this paper, we focus on a dynamic spectrum access strategy for Internet of Things (IoT)
applications in two types of radio systems: cellular networks and cognitive radio-enabled low …

To solve the contradiction between the increasing demand of diverse vehicular wireless
applications and the shortage of spectrum resource, a novel cognitive cooperative vehicular …

Cognitive radio, which will become a fundamental part of the Internet of Everything (IoE), has
been identified as a promising solution for the spectrum scarcity. In a multi‐SU and multi‐PU …

The allocation of spectrum resources efficiently and equitably in dynamic cognitive vehicular
networks is more challenging than static cognitive networks. Currently, most spectrum …

In cognitive radio (CR) networks, secondary users should effectively use unused licensed
spectrums, unless they cause any harmful interference to the primary users. Therefore …

The quality of service (QoS) is important issue for cognitive radio networks. In the cognitive
radio system, the licensed users, also called primary users (PUs), are authorized to utilize …

In this paper, we propose a cross-layer architectural framework for network and channel
selection in a heterogeneous cognitive wireless network (HCWN). Existing research on …

Real-time information exchange on traffic and channel selection results among users in
dynamic spectrum access (DSA) system consumes scarce spectrum resources. However, it …

This study introduces two novel approaches, pre-partitioning and weight-driven exploration,
to enable an efficient learning process in the context of cognitive radio. Learning efficiency is …
