In this paper we consider resource allocation for an OFDMA-based cognitive radio point-to-
multipoint network with fixed users. Specifically, we assume that secondary users are …

The new era of the Internet of Things (IoT) applications is driving the evolution of
conventional Vehicle Ad-hoc Networks into the Internet of Vehicles (IoV). In the IoV …

As a futuristic solution to the serious scarcity of spectrum and radio resources in today's
scenario, cognitive radio offers great solutions. Cognitive radio is a groundbreaking …

The increasing demand of diverse vehicular network oriented applications (both safety and
non-safety related services would undoubtedly lead to shortage of spectral resource …

In cognitive radio (CR) systems, reasonable power allocation can increase transmission rate
of CR users or secondary users (SUs) as much as possible and at the same time insure …

Cognitive radio (CR) in conjunction with multiple-input multiple-output (MIMO) orthogonal
frequency-division multiple access is a candidate technology for future mobile radio …

In this paper, we investigate the energy consumption issue in cognitive radio (CR) networks.
We aim to maximize the energy efficiency of the CR network while considering practical …

The Internet of Things (IoT) is a network of interconnected objects, in which every object in
the world seeks to communicate and exchange information actively. This exponential growth …

With rapid development of the Internet of Things (IoT), various machine-to-machine
communications technologies have emerged in recent years to provide ubiquitous wireless …

There are different types of messages containing different priorities in vehicular ad hoc
networks. Hence, queue rescheduling is required according to priorities of arrived …
