In this survey paper, we characterize the learning problem in cognitive radios (CRs) and
state the importance of artificial intelligence in achieving real cognitive communications …

This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

In this paper, a new spectrum sharing model referred to as riding on the primary (ROP) is
proposed for wireless-powered IoT devices with ambient backscatter communication …

Dynamic spectrum leasing (DSL) was proposed recently as a new paradigm for dynamic
spectrum sharing (DSS) in cognitive radio networks (CRN's). In this paper, we propose a …

Cognitive Radio (CR) is a dynamic spectrum access approach, in which unlicensed users
(or secondary users, SUs) exploit the underutilized channels (or white spaces) owned by the …

Dynamic spectrum leasing (DSL) is one of the schemes proposed for dynamic spectrum
sharing (DSS) in cognitive radio networks. In DSL, spectrum owners, denoted as primary …

Dynamic spectrum leasing (DSL) has been proposed as a solution for better spectrum
utilization. Most of the work focused on non-cooperative game to model primary/secondary …

We propose a new architecture for dynamic spectrum sharing called the distributed dynamic
spectrum leasing (D-DSL) and a game-theoretic framework for its implementation on a …

Wireless systems, spectrum handover, and radio networks have experienced a drastic
transition due to modern-day technological initiatives. This advancement is evident in the …

The problem of resource allocation in a spectrum leasing scenario in cooperative cognitive
radio networks is addressed. The system model consists of a number of primary user (PU) …
