What is Digital Twin

Applications of Artificial Intelligence in Wireless Communication Systems
Digital twins are the digital replicas of any physical object in the physical world, in terms of its physical properties and its behaviour. They are modelled by acquiring information about their characteristics using sensors.

Abstract
Metaverse is the future of internet and an amalgamation of VR, AR, blockchain technology, AI, and 5G, and beyond. Metaverse can be seen as a self-sustaining system with its economy, structure, and trade of virtual items. Currently, there is no common platform for this in a decentralized manner. Thus, there is a need for an interdependent architecture that can provide interaction amongst layers. This chapter focuses on a seven-layered architecture that is simple to comprehend theoretically but cannot represent the true essence of all aspects of Metaverse. Hence, a novel interdependent architecture that includes physical and virtual world interaction is proposed in this chapter. Next, some potential applications and services of Metaverse are discussed. Later, two case studies, that of a virtual city and a virtual university campus using Metaverse, were analyzed based on the proposed architecture. Finally, the chapter is concluded with the open issues and challenges faced while dealing with Metaverse.
