Special Issue Information

Dear Colleagues,

The introduction of 5G technology globally is driving radio access network densification, new network architectures, and innovative use cases with stringent performance requirements (e.g., throughput, latency, and reliability). To fulfill the ever-increasing demand of high data rates and improvement in the user-experienced quality-of-service (QoS), and to accommodate massive device connectivity to the network, the communication industry is readily advancing towards the implementation and realization of 5G and beyond 5G (B5G) wireless technologies, respectively. Consequently, an emerging trend of 5G and B5G technology in mobile communications systems is creating a new demanding challenge for antenna designers and researchers. Along with antenna miniaturization aspects, the industry demands designing an antenna that should meet all commercial aspects within a single structure, which makes them more attractive. Due to an increasingly demanding compatibility of standards such as Bluetooth, Wi-Fi, 4G/5G, GPS, etc., the designers must face challenges while designing antennas that must include interference problems, integration of different wireless standards, and tuning capabilities.

The increase in mobile data traffic given in this 5G and B5G mobile communication will lead to the already well-known expansion methods or the implementation of new ones such as the use of multi-beam antennas, which means an increase in coverage. Similarly, miniaturization procedures, integrated antennas, MIMO systems, group optimization, and bandwidth enhancements, among others, obtained great significance. In the future, 6G will have a broader frequency band, improved spectrum efficiency, higher transmission rate, shorter delay, no latency issues, greater connection capacity, wider coverage, stronger anti-interference capability, and multi-standard wireless application to satisfy various networks requirements.

This Special Issue aims to collect relevant papers describing the latest advances and prospects in antenna design for mobile communications. You are cordially invited to submit a contribution of either original research or a review article to this Special Issue. The objective of this Special Issue is to report a novel trend in the development of antennas and microwave components including active circuits and passive structures for mobile communication applications. The topic of interest covers design and modeling techniques, optimization techniques, synthesis methods, integration techniques, including but not limited to:

  • 5G and beyond mobile communication
  • MIMO antennas
  • Antenna design challenges
  • Reconfigurable antennas
  • Integrated antennas for multi-wireless applications
  • Mutual coupling reduction in MIMO antennas
  • Fractal antennas
  • Switchable antennas for wireless communication
  • Miniaturization of mobile antennas
  • URLLC application
  • URLLC antenna challenges
  • UWB antennas for microwave imaging applications

The deployment of millimeter waves can fulfil the stringent requirements of high bandwidth and high energy efficiency in fifth generation (5G) networks. Still, millimeter waves communication is challenging because it requires line of sight (LOS). The heterogeneous network (HetNet) of millimeter waves and microwaves solves this problem. This paper proposes a millimeter -microwaves heterogeneous HetNet deployed in an indoor factory (InF). In InF, the manufacturing and production are performed inside big and small halls. We consider non standalone dual-mode base stations (DMBS) working on millimeter waves and microwaves. We analyze the network in terms of throughput and energy efficiency (EE). We formulate mixed-integer-non-linear-programming (MINLP) to maximize the throughput and EE of the network. The formulated problem is a complex optimization problem and hard to solve with exhaustive search. We propose a novel outer approximation algorithm (OAA) to solve this problem, and the proposed algorithm OAA achieves optimal solution at β = 10−3. At this β, the average throughput value obtained is approximately 50 Mbps, whereas the value of EE is 4.4 Mbits/J. We also compare the performance of OAA with the mesh-adaptive-direct-search-algorithm (NOMAD), and the experimental results verify that OAA outperforms NOMAD in terms of throughput and EE maximization. We also compare the performance of OAA with particle swarm optimization (PSO), genetic algorithm (GA), and many others optimization algorithms. Experimental results verify that OAA outperforms all other algorithms. Full article

A mobile ad hoc network (MANET) is a group of nodes constituting a network of mobile nodes without predefined and pre-established architecture where mobile nodes can communicate without any dedicated access points or base stations. In MANETs, a node may act as a host as well as a router. Nodes in the network can send and receive packets through intermediate nodes. However, the existence of malicious and selfish nodes in MANETs severely degrades network performance. The identification of such nodes in the network and their isolation from the network is a challenging problem. Therefore, in this paper, a simple reputation-based scheme is proposed which uses the consumption and contribution information for selfish node detection and cooperation enforcement. Nodes failing to cooperate are detached from the network to save resources of other nodes with good reputation. The simulation results show that our proposed scheme outperforms the benchmark scheme in terms of NRL (normalized routing load), PDF (packet delivery fraction), and packet drop in the presence of malicious and selfish attacks. Furthermore, our scheme identifies the selfish nodes quickly and accurately as compared to the benchmark scheme. Full article

Fifth-generation (5G) technology will play a vital role in future wireless networks. The breakthrough 5G technology will unleash a massive Internet of Everything (IoE), where billions of connected devices, people, and processes will be simultaneously served. The services provided by 5G include several use cases enabled by the enhanced mobile broadband, massive machine-type communications, and ultra-reliable low-latency communication. Fifth-generation networks potentially merge multiple networks on a single platform, providing a landscape for seamless connectivity, particularly for high-mobility devices. With their enhanced speed, 5G networks are prone to various research challenges. In this context, we provide a comprehensive survey on 5G technologies that emphasize machine learning-based solutions to cope with existing and future challenges. First, we discuss 5G network architecture and outline the key performance indicators compared to the previous and upcoming network generations. Second, we discuss next-generation wireless networks and their characteristics, applications, and use cases for fast connectivity to billions of devices. Then, we confer physical layer services, functions, and issues that decrease the signal quality. We also present studies on 5G network technologies, 5G propelling trends, and architectures that help to achieve the goals of 5G. Moreover, we discuss signaling techniques for 5G massive multiple-input and multiple-output and beam-forming techniques to enhance data rates with efficient spectrum sharing. Further, we review security and privacy concerns in 5G and standard bodies’ actionable recommendations for policy makers. Finally, we also discuss emerging challenges and future directions.
