The article presents the discussion on paradigm of virtualization evolving from a virtualized local area network (LAN) and private networks to the solidification of network function virtualization (NFV). Topics include coupled with the pervasive utilization of artificial intelligence (AI) at all network levels; and the Digital Twin (DT) paradigm recently deemed as a promising tool for network design, optimization, management.

The article presents the discussion on considerable aspects of face-to-face human interactions remain difficult to relay. Topics include computer's ability capturing a human's emotion called affective sensing, alternatively called emotion sensing and more recently emotional artificial intelligence (emotional AI); and use of emotions in crowd and traffic management; to relaying emotions to and from the metaverse.

The article presents the discussion on meaning or semantics of the data. Topics include advancements in artificial intelligence (AI) providing a powerful tool for solving fundamental problems in semantic communications; and semantic communications in emerging wireless networks such as virtual reality and autonomous driving.

The article discusses the met averse services and business models and Met averse architectures. Topics include the ways of social interaction are significantly augmented with persistent virtual content, consumed via VR or AR; met averse is an emerging concept which embraces three important elements, and Experimental demonstrations and prototypes of met averse.

The article reports that over time, the capacity of networks has dramatically increased, thanks to advances in optical communications. However, the Internet traffic is still growing every year which forces network operators to look for efficient solutions to manage this traffic. Since the advent of Software-Defined Networking (SDN), the majority of researchers focus their attention on centrally managed networks with efficient traffic management solutions.

The article reports that In contrast to the Shannon paradigm whose underlying principle is to guarantee the correct reception of each single transmitted packet regardless of its meaning, semantic communication is concerned with the problem of how transmitted symbols convey a desired meaning to the destination, as well as how effectively the received meaning affects the action in a desired way.

The article reports that The metaverse is an emerging concept which embraces three important elements. First, it embraces a social element, i.e. it is not only a virtual space where users spend time (and money) on their own or with a selected few. Rather, the metaverse is intended to resonate with the very social fabric which underpins human society.

The article reports that With the continued growth of IoT devices and their deployment, manually managing and connecting them is impractical and presents multiple challenges. To that end, Zero Touch Networks that rely on software-based modules instead of dedicated propriety hardware become a viable potential solution. The overall aim of zero-touch networks is for machines to learn how to become more autonomous so that we can delegate complex, mundane tasks to them.

The article offers information on the journal's call for papers on topics like military communications and networks, internet of things, and artificial intelligence and data science for communications.
