Abstract Cognitive Radio Networks have been emerged as a promising solution for solving
the problem of spectrum scarcity and improving spectrum utilization by opportunistic use of …

The demand for spectrum resources has increased dramatically with the advent of modern
wireless applications. Spectrum sharing, considered as a critical mechanism for 5G …

The three-tier spectrum sharing framework (3-TSF) is a spectrum sharing model adopted by
the Federal Communications Commission. According to this model, under-utilized federal …

New research directions will lead to fundamental changes in the design of future WiFi
networks. However, with an explosion of wireless mobile applications and services, there …

We consider a secondary spectrum market where primaries set prices for their unused
channels. The payoff of a primary then depends on the availability of channels for its …

To meet the ever growing need for wireless spectrum, the Federal Communication
Commision (FCC) introduced a spectrum sharing model called the 3-Tier Sharing …

The performance of cognitive radio‐based wireless local area networks (WLANs) is affected
by channel conditions, the contention processes of unlicensed/secondary users (SUs) and …

The demand for wireless technology has outpaced the ability for the many disparate
spectrum systems to coexist and satisfy increasing performance constraints, warranting the …

With the increasing use of smart devices recently, mobile traffic has been increasing rapidly,
which in turn has resulted in greater demand for frequency. Many countries have attempted …

Wi-Fi is a term that most of us hear almost every day and is a service most would consider
an integral part of our lives. From our smart phones to our game consoles and computers …
