Green Technologies for the Sustainable Metaverse and Web 3.0

The concepts of Metaverse and Web 3.0 have surged in popularity, heralded as the “successor to the mobile Internet.” Web 3.0 represents a transformative shift in the Internet landscape, emphasizing user-centric decentralization. These core principles of Web 3.0 find their fullest realization in the Metaverse, which represents the next evolutionary stage of the Internet. The Metaverse envisions a seamless and interoperable fusion of Artificial Intelligence (AI) driven virtual worlds, enriched by user-generated content (UGC), and accessible through virtual/augmented reality (VR/AR) technologies. However, the around-the-clock maintenance of the Metaverse will require intensive computation load and heavy data traffic. Therefore, network densification must continually increase while adhering to stringent data rate and latency constraints, as well as the extreme bandwidth demands imposed by Metaverse applications. Under these circumstances, it becomes imperative to explore green technologies as a means to realize the sustainable development of the Metaverse. In this Special Issue, we have received a large number of submissions, and after rounds of careful reviews, we chose 10 papers for publication after a thorough revision process by at least two independent referees.
