Hybrid precoding design for secure smart-grid enabled MIMO wireless communications in Industry 5.0

This paper presents a System on a Chip (SoC) Field-Programmable Gate Array (FPGA) implementation for Media Access Control (MAC) layer of a fast industrial Wireless Local Area Network (iWLAN) protocol, which is used to control industrial robots in factory automation environments. This protocol is a potential technique for industrial wireless communication system by using the Low overhead Packet Division Multiple Access (PDMA) scheme controlled by MAC layer. In our previous research, the MAC layer hardware was implemented and tested on simulation software, but the SoC design for the MAC layer has not been implemented and real tested on the FPGA. In this paper, we have successfully implemented the SoC system for MAC layer of this high-speed wireless communication protocol on the FPGA.

Physical layer security (PLS) in wireless communication systems has attracted extensive research attentions in recent years. Unlike cryptography-based methods applied in upper-layer in network, PLS methods are applied in physical layers and can provide information-theoretic security by utilizing the randomness of signals and wireless channels. In this survey, we provide a comprehensive review in the domain of physical layer authentication (PLA) in wireless communication systems, including the concepts, several key techniques of typical PLA architectures as well as future challenges and research trends in more sophisticated communication systems. The survey begins with an overview of the background and basic concepts of PLA, such as the general model of wireless security communication system, typical frameworks of key-based/less PLA systems, and the common attack models. We then discuss the major concerns and key techniques that are applied in PLA systems, where three types of authentication schemes are considered, i.e., the authentication based on channel information, radio-frequency and identity watermarks. Basic models and representative research results about key approaches and techniques applied to the authentication systems above are subsequently covered. Finally, the associated challenges and potential research trends of PLA in future communication systems are presented at the end of the survey paper.

Increasingly, smart grid solutions use wireless communications as a core component for moving information and, thus, facilitate more intelligent decision making. This article considers a synchrophasor system implemented on a distribution feeder simultaneously using two separate wireless communication technologies to transmit synchrophasor measurement data. This system was implemented to demonstrate advanced distributed-generation control and how it impacts grid support on the broader electrical feeder. For purposes of performance evaluation, both a wireless serial communications solution and a third-generation (3G) cellular solution were implemented. Phasor measurement unit (PMU ) data, which are streamed without interruption up to 60 messages/s, offer a means to continuously evaluate the two communications systems; performance data measured and archived over a one-week period provided detailed comparison information. Using this information, this article recommends which wireless technology may be better suited for various utility applications.

In order to solve the problems of low-risk assessment accuracy and long time-consuming assessment of current wireless mobile communication systems, a wireless mobile communication system based on artificial intelligence algorithms is proposed.

The purpose of the study: to develop a communication system that provides a wireless channel for transmitting information through the thickness of conductive matter.

Computer facilities and microprocessor-based technology have been successfully used in the energy industry. For protection and equipment control, this technology has been used in SCADA, remote control and monitoring applications. Particular attention is paid to the cyber security sector for automation and control systems. Protective application of the equipment and control, SCADA, monitoring and remote control, uses the technology with microprocessor. Due to the great importance of the power supply process, there is no question of being left in a state of vulnerability and neglect. Security is not perfect and will never be. For this reason, there will always be security breaches and incidents. Also, for this reason, not only protection mechanisms are in place, but also mechanisms for rapid detection of incidents and which are able to react effectively to the isolation of problems and to ensuring security. Processes security for systems will continue to evolve in the future. By definition, there are no communication systems that are 100% safe. Attacks against critical industrial infrastructures marked an increase not only in terms of number but also of the level of complexity. The destruction of the industrial control system (ICS) and critical processes were interrupted. For many organizations, the security improvement in ICS systems is great. The extreme sensitivity to ensure the availability and performance of industrial processes has led to a more conservative and rigorous approach to how security measures are implemented. Cyber-attacks that could compromise the availability, integrity, and confidentiality of ICS systems may come from within systems or from outside ICS systems. Among the ICS system infection vectors from the perspective of the SANS Institute (2014) include: external threats (state attacks, hacking etc.), malware, exploiting tools, phishing, internal attacks, cyber security protocols, and industrial espionage. This chapter addresses the cyber security issues required for the protection, automation, control and communications systems of transformation stations as well as methods that could be used to prevent computer attacks that can have a significant impact on the availability of the system Electro-energetic effect with serious consequences on extended area interruptions.

The subject of research in this article is the process of building a mobile communication system that operates under electronic countermeasures. The aim is to develop recommendations for building a wireless mobile communication system that operates effectively in a complex interfering electromagnetic environment. The strategy for building a mobile wireless communication system is based on the use of a grouping of low-altitude UAVs with ultra-wideband signal technology circulating in control and communication channels, with the integration of artificial intelligence elements into its structure. The objective of this study is to ensure the stable and secure operation of a wireless mobile communication system despite electronic countermeasures. The methods of analytical, temporal positional pulse coding, and fuzzy logical inference were used to make decisions on the transfer of service in the network. The following results were obtained. A strategy for building a wireless mobile communication system despite electronic countermeasures has been developed. It is shown that in order to obtain high noise immunity of control and communication channels and to protect information from interception, wireless ultra-wideband communication technology should be used. This will provide large volumes and speeds of information transmission. A technical solution for the design of an ultra-wideband transceiver antenna system is proposed. Moreover, it is recommended to use the results of data processing in a fuzzy decision-making system for the transfer of service between mobile network nodes in conditions of interference. Conclusions. The scientific novelty of the obtained results is as follows. The use of ultra-wideband channels makes it possible to increase the number of control and communication channels in a wireless mobile system almost unlimitedly. The preliminary distribution of orthogonal codes between the channels realizes the process of control and communication without the interception of information and mutual interference. The use of the time-position-pulse coding method prevents the occurrence of intercharacter distortions of the encoding ultrashort pulses. This also reduces the level of distortion of information signals caused by multipath propagation, which guarantees the security of information in the system. The use of a fuzzy decision-making system for the transfer of services between mobile network nodes allows dynamically changing the network topology in real time and maintaining high quality of service under electronic countermeasures.

The transfer of information from source to destination i.e transmitter to receiver is called the communication. Basically communication is possible in two ways they are wire communication and the other one is wireless communication. The satellite communication is a best example for the wireless communication. The Satellite communication has served making in many ways from instance its is used to predict weather and broadcast storm warnings and also provides a wide range of communication services in the fields of relaying television programs, point to point communication, voice, data, internet, fax. Wireless communication is the transfer of information or power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves. With radio waves distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants, and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound.

The article deals with the issues of interference and intelligence protection of radio communication means of the mobile component of the tactical command and control link in the conditions of active use of electronic warfare. The problems arising from the use of standard radio communication means that do not provide a sufficient level of protection against intentional interference and interception of signals by the enemy are analysed. The necessity of developing a scientific and methodological apparatus for adapting the radio networks of the National Guard of Ukraine to the conditions of active interference is substantiated. An analysis of modern radio communication equipment used in the military, including portable radios, satellite communication systems, tactical Wi-Fi solutions and software-based radio networks, is carried out. It is determined that the existing communication systems do not provide effective counteraction to enemy radio jammers, especially in direct contact. A new method of spatial interference rejection based on the optimal location and direction of antenna systems of ground-based transmitters and receivers of UHF/VHF and Wi-Fi radio signals is proposed. The proposed method takes into account the tactical situation, the territorial location of radio network nodes and allows to increase the interference immunity of radio channels by changing the characteristics of antenna systems. A mathematical model of interaction between the elements of the radio communication system and active radio masking means is substantiated, which allows determining the optimal parameters of antenna systems and radiation power. The threshold values of the suppression coefficient are determined, at which the required quality of signal reception is guaranteed under the conditions of targeted concentrated interference. The concept of a stable radio communication zone is expanded, in particular, the dependence of its area on the shape of the radiation pattern and the distance between the elements of the communication system is substantiated. For the first time, a comprehensive analysis of the combined effect of intentional interference and active radio jamming on the stability of radio channels is carried out, which allows a reasonable approach to planning radio communications in the conditions of electronic warfare. An algorithm for determining the area of stable exchange for the points of the operational map of combat operations is proposed, which allows to effectively plan the location of communication means and active radio masking means. The practical significance of the obtained results lies in the possibility of applying the developed method in the creation of adaptive radio communication systems that take into account the real tactical situation, which can significantly increase the efficiency of troop management in the conditions of information influence of the enemy.

In June 2022, the phreatic eruption of the Bulusan Volcano affected northwestern towns in Sorsogon, causing power outages, road closures, and forced evacuations. This study examines the role of the Very High Frequency (VHF) radio communication system in disaster response. Using a qualitative method—specifically, Focused Group Discussions (FGDs) and interviews—insights were gathered from key responders, village officials (barangay officials), and part-ner agencies with direct involvement. Thematic analysis was employed to identify key themes related to communica-tion effectiveness, system reliability, and operational challenges. Purposive sampling included diverse participants, utilizing both homogeneous groups for specific discussions and heterogeneous groups for varied perspectives. This study found that the VHF radio system enhanced coordination and information dissemination when cellular networks in Sorsogon became unavailable. These findings align with Cid et al. (2017): despite limited availability and weak signals in some areas, the resilience of VHF radio maintained communication inside and outside disaster zones. Fur-thermore, communities equipped with VHF radios enabled continuous communication at the local and municipal lev-els. Significant challenges, however, arose, such as weak signals in remote areas, limited radio availability, and delays in information flow. The findings of Andreastuti et al. (2023) suggest that community participation in collaboration with local leaders enhances local disaster response mechanisms, including VHF radio communication, before, during, and after disasters.
