Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

In this article, we investigate a computing task scheduling problem in space-air-ground
integrated network (SAGIN) for delay-oriented Internet of Things (IoT) services. In the …

As an important technology to ensure data security, consistency, traceability, etc., blockchain
has been increasingly used in Internet of Things (IoT) applications. The integration of …

The Internet of Things (IoT) has significant importance in the beyond fifth generation (B5G)
communication systems. However, the IoT is vulnerable to disasters because the network is …

Wireless communications have gained huge attention over the past decades because of
continuously increasing demands. The main goal of all wireless network designers is to …

Energy-efficiency (EE) is critical for device-to-device (D2D) enabled cellular networks due to
limited battery capacity and severe cochannel interference. In this paper, we address the EE …

6G networks provide faster communication for connected vehicles. These vehicles are
connected to the Internet, forming the Internet of Vehicles (IoV). Due to the development of …

The incorporation of cognitive radio (CR) and energy harvesting (EH) capabilities in wireless
sensor networks enables spectrum and energy-efficient heterogeneous CR sensor networks …

Wireless sensor networks operating in the license-free spectrum suffer from uncontrolled
interference as those spectrum bands become increasingly crowded. The emerging …

In this paper, we study resource management and allocation for energy harvesting cognitive
radio sensor networks (EHCRSNs). In these networks, energy harvesting supplies the …
