The ever-growing demand for higher network data rates, lower delay, and conservative
energy consumption at reduced costs, to support Internet-of-things (IoT) communications …

The problem of inefficient and unevenly distributed spectrum usage in industrial wireless
networks has led to the emergence of the concept of industrial cognitive radio (CR) …

Collision-free transmission and efficient data transfer between nodes can be achieved
through a set of channels in multichannel wireless sensor networks (MWSNs). While using …

In the era of Internet-of-things (IoT), the future 5G networks are supposed to provide
ubiquitous connectivity, high speed, as well as low latency and energy efficiency at low cost …

In this paper, we propose a novel system state aware multichannel protocol for energy
harvesting cognitive radio networks (EH-CRNs). In contrast with the state-of-the-art …

Cognitive Sensor Networks (CSNs) are significantly different from the traditional WSNs in
terms of Cognitive Radio (CR) technology. According to the surrounding environment …

The spectrum scarcity crisis has resulted in a shortage of resources for many emerging
wireless services, and research on dynamic spectrum management has been used to solve …

Wireless communication technologies are develo** directly proportional to the need and
demand for these technologies. Therefore, studies in this direction are gaining importance …

We study the minimum diameter spanning tree problem under the reload cost model
(Diameter‐Tree for short) introduced by Wirth and Steffan. In this problem, given an …

Abstract As the Cognitive Radio (CR) overwhelms spectrum deficiency, it offers a substantial
communication environment to accommodate IoT devices demanding connectivity and …
