Low-Latency Communications for Digital Twin Empowered Web 3.0

The vision of Web 3.0 is to promote decentralized, intelligent, and autonomous Internet by self- learning and self-adaption of user demands. Such Internet evolution is enabled by ubiquitous and low-latency communication and powerful computing, imposing significant challenges on the Web 3.0 architecture and its network orchestration. The successful implementation of Web 3.0 relies on dynamic perception and intelligent decision-making, which is difficult to conceive owing to the heterogeneity and dynamics of networks. Digital twins, as an emerging technology, can map the real-time network status and make optimal decisions to enable intelligent low- latency communications. This article introduces a digital twin architecture to achieve networking virtualization and digitalization for Web 3.0. Based on the architecture, the digital twin-empowered low-latency communication scheme is proposed by disseminating tasks to the resource- sufficient infrastructure, while considering the communication cost of deploying digital twins. Illustrated results demonstrate the superiority of digital twins for low-latency communications in Web 3.0.
