As the data traffic is increasing, the spectrum bands are getting congested. It causes low
latency and unreliable communication. Additional spectrum can be utilized to solve this …

Cognitive Radio (CR) is an emerging wireless communication technology that offers a great
solution to scarcity of radio spectrum. Cognitive Radio Network (CRN) is an intellectual …

With the increasing number of wireless communication devices, there may be a shortage of
non-licensed spectrum, and at the same time, licensed spectrum may be underutilized by …

The cognitive network suffers from scarcity of channels. The Unlicensed users (UU) borrow
channels from the licensed users (LU). But when the LUs want them, the UUs have to stop …

Cognitive radio networks sets priority for users to provide improved QoS for primary users. In
most cognitive radio networks the primary user is assigned highest priority for …

Cognitive radio is a wireless technology that provides solution to meet scarcity of radio
spectrum. Here primary channel sensing and selection of appropriate vacant channel for …

In this paper, we propose an efficient distributed channel selection strategy DCSSfor
