With growing concern about environmental issues and an emerging green communications
paradigm, cognitive radio (CR) networks (CRNs) have to be considered from the energy …

IEEE 802.15. 4e Time Slotted Channel Hopping (TSCH) standard has gained a lot of
attention within the Industrial Internet of Things research community due to its effectiveness …

In this paper, we develop an opportunistic spectrum-scheduling scheme for multichannel
cognitive radio networks. In the proposed scheme, the primary user activity and channel …

Spectrum sharing is a key function to provide fairness allocation as well as service
satisfaction across multiple users in cognitive radio networks. Even though spectrum sharing …

The massive influx of mobile devices and their increasing use in recent years have resulted
in the overprovision of access points (APs) in networks. Unlike in residential environments …

In this paper, we define a cluster based scheduling algorithm for Cognitive Radio Sensor
Networks. To avoid inter-clusters collision, we assign fixed channels only to nodes having …

The proliferation of wireless technologies and services has intensified the demand for the
radio spectrum. However, the currently existing fixed spectrum assignment policy leads to an …

This paper investigates the problem of spectrum assignment and sharing to minimize the
total delay of multiple concurrent flows in multi-hop cognitive radio networks. We first …

Current Wireless Sensor Networks (WSNs) are deployed over unlicensed frequency bands
that face an increased level of interference from various wireless systems. Cognitive Radio …

Abstract Internet of Things (IoT) is a widely adoptable technology in industrial, smart home,
smart grid, smart city and smart healthcare applications. The real world objects are remotely …
