“…4) Mobile edge computing (MoEC): MoEC, which was first proposed by the European telecommunications standards institute (ETSI) in 2014 [74], is thought to be a good alternative to the current centralized cloud by geographically distributing resources close to edge IIoT devices. MoEC aims to relieve network congestion, speed up response, attain high energy efficiency, and maintain context-awareness in 5G and beyond [75], [76].…”

Fifth generation (5G)-industrial Internet of things (IIoT) is the integration of IIoT and a private 5G network. The IIoT is a concept that involves incorporating smart objects, gadgets, and solutions into cutting-edge industrial operations to increase reliability, efficiency, and over-production costs. Furthermore, the integration of IIoT and 5G/beyond 5G (B5G) provides the potential for ubiquitous and instantaneous connectivity. The 5G architecture can handle the IIoT's stringent ultra-low latency, real-time processing, high data rate, nearby storage, and reliability requirements. A new era of economic growth is predicted for IIoT-assisted 5G/B5G wireless networks. It should be noted that the majority of the work in IIoT is focused on the architecture, with reliability and throughput being largely ignored. This paper provides a comprehensive review of B5G assisted IIoT wireless networks, with a focus on enhanced mobile broadband (eMBB) and ultra-reliable low latency communication (URLLC) services. Furthermore, it provides insights into various applications and key enabling technologies from the perspective of URLLC, eMBB, and their tradeoff.Index Terms-Fifth generation (5G), beyond 5G (B5G), sixth generation (6G), industrial Internet of things (IIoT), ultrareliable low latency communication (URLLC), enhanced mobile broadband (eMBB). I. INTRODUCTIONT HE emergence of industrial Internet of things (IIoT) has revolutionized industrial operations such as manufacturing and production by automating a huge number of connected components and devices. IIoT is a sub-category of Internet of things (IoT) that focuses on the use of IoT techniques and technologies [1]-[4] in industries such as smart cities, smart transportation, smart grid, smart health services, forestry, food, weather, agriculture, monitoring, and surveillance [5]-[18]. The machines/devices in IIoT are connected to capture smartness and autonomy in legacy systems [19]-[21]. It is estimated that by the end of 2030, roughly 80 billion devices will be connected to the Internet [22]-[24]. In IIoT, an increased degree of connectivity is involved, which has special requirements for high reliability, low latency, high speed, more flexibility, and secure communication [25]-[27].

Industrial Internet of Things is an ultra-largescale system that is much more sophisticated and fragile than conventional industrial platforms. The effective management of such a system relies heavily on the resilience of the network, especially the communication part. Imperative as resilient communication is, there is not enough attention from literature and a standardized framework is still missing. In awareness of these, this paper intends to provide a systematic overview of resilience in IIoT with a communication perspective, aiming to answer the questions of why we need it, what it is, how to enhance it, and where it can be applied. Specifically, we emphasize the urgency of resilience studies via examining existing literature and analyzing malfunction data from a real satellite communication system. Resilience-related concepts and metrics, together with standardization efforts are then summarized and discussed, presenting a basic framework for analyzing the resilience of the system before, during, and after disruptive events. On the basis of the framework, key resilience concerns associated with the design, deployment, and operation of IIoT are briefly described to shed light on the methods for resilience enhancement. Promising resilient applications in different IIoT sectors are also introduced to highlight the opportunities and challenges in practical implementations.

Power supply for small-scale battery-powered systems such as electric vehicles (EVs and mobile robots) is being actively researched. We are particularly interested in energy management, which considers the interconnection of such systems close to each other. This allows for overall redundancy to be maintained without assuming excessive redundancy with individual power sources. Its implementation necessitates a high level of integration between power management and information and communication technology. As one of these methods, this study investigates energy management based on power packetization. When the individual systems to be connected have moving parts or are mobile, wireless power transmission is a promising method for power sharing. However, power packetization has so far only been considered for wired transmission. In this paper, we address the integration of power and information in wireless channels using power packetization. We propose a power packet router circuit that can wirelessly transmit power over multiple channels selectively. Furthermore, we demonstrate that the developed system can handle both wired intrasystem power management and wireless intersystem power sharing in a unified manner.
