Abstract
A digital twin DT is a technology that creates virtual representations of real-world entities. In the context of the networking area, this concept is applied as the network digital twin NDT for efficient network management. Recently, this promising technology has been thoroughly discussed in recent research, and several surveys have studied NDT from different perspectives. This review focuses on the specific applications and objectives of NDT within the Internet of Vehicles IoV ecosystem. It classifies NDT use cases in IoV networks into the four main classes, including resource management, path planning, power management, and predictive maintenance. The classification indicates that NDT can assume various models and multiple capabilities to address the complex challenges of modern IoV networks. This comprehensive overview has a twofold objective: to show how IoV can benefit from NDT, and to outline the principal challenges and opportunities that need to be addressed by future research.
期刊介绍：
Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
