“…Low-cost systems and battery-powered devices, such as the IoT devices, may not afford the high complexity and hardware requirements of CS. For this reason, many studies focus on analyzing and lowering the cost of applying the CS in IoT networks [ 27 , 193 , 194 , 195 ].…”

Spectrum Sensing (SS) plays an essential role in Cognitive Radio (CR) networks to diagnose the availability of frequency resources. In this paper, we aim to provide an in-depth survey on the most recent advances in SS for CR. We start by explaining the Half-Duplex and Full-Duplex paradigms, while focusing on the operating modes in the Full-Duplex. A thorough discussion of Full-Duplex operation modes from collision and throughput points of view is presented. Then, we discuss the use of learning techniques in enhancing the SS performance considering both local and cooperative sensing scenarios. In addition, recent SS applications for CR-based Internet of Things and Wireless Sensors Networks are presented. Furthermore, we survey the latest achievements in Spectrum Sensing as a Service, where the Internet of Things or the Wireless Sensor Networks may play an essential role in providing the CR network with the SS data. We also discuss the utilisation of CR for the 5th Generation and Beyond and its possible role in frequency allocation. With the advancement of telecommunication technologies, additional features should be ensured by SS such as the ability to explore different available channels and free space for transmission. As such, we highlight important future research axes and challenging points in SS for CR based on the current and emerging techniques in wireless communications.

“…The emerging wireless power transfer technology promotes wireless powered networks (WPNs) where nodes are powered by energy access point to communicate with data access point [1]. In order to maintain continuous and uninterrupted information acquisition and transmission, reduce maintenance costs and improve energy efficiency, naturally it has become necessary to supply energy to WSN with environmental energy [2], [3].…”

In the wireless powered communication network (WPCN), the wireless energy acquisition is weak due to the fading characteristic of the wireless link, which is hard to supply energy to wireless sensor. Reconfifigurable intelligent surface (RIS) is a promising performance enhancing technology for WPCN, which can improve the energy and spectral effificiency, expand the network coverage, and thus improve the throughput. This paper proposes a new framework for energy harvesting and information transmission of non-orthogonal multiple access (NOMA) based WPCN aided by the RIS. The total transmission capacity is maximized by joint optimization energy beamforming, information beamforming and the RIS phase shift, which turns out to be a non-convex problem. By exploiting the iterative optimization and maximal ratio combining (MRC) algorithm, the energy beamforming and information beamforming are determined for single-and multi-user system, respectively. Numerical results prove that compared with the non-RIS-aided system, the proposed scheme can increase the throughput of the multi-user system.

Security of data is very important while providing communication either by the wired or wireless medium. It is a very challenging issue in the world and the wireless mobile network makes it more challenging. In a wireless mobile network, there is a cluster of self-contained, self-organized networks that form a temporarily multi-hop peer-to-peer radio network, lacking any use of the pre-determined organization. As these networks are mobile and wireless connection links are used to connect these networks through each other, many of the times these kinds of networks are accomplished of self-manage, self-define, and self-configure. Due to their dynamic nature, wireless mobile networks/systems do not have a fixed infrastructure and, due to this, it is more vulnerable to many types of hostile attacks. Different kinds of security attacks that are present in wireless mobile networks are stated in the paper with their spotting and precaution techniques. Furthermore, the paper deliberates on the various types of mobile networks along with their numerous challenges and issues. Moreover, the paper defines the need and goals of security in wireless mobile networks as well as many security attacks along with their detection or prevention methods.
