Digital Twin-Assisted Edge Computation Offloading in Industrial Internet of Things With NOMA

Abstract: Integrating digital twins (DTs) and multi-access edge computing (MEC) is a promising technology that realizes edge intelligence in 6G, which has been recognized as the key enabler for Industrial Internet of Things (IIoT). In this paper, we explore a DT-assisted MEC system for the IIoT scenario where a DT server is created as a digital counterpart of the MEC server, via estimating the computation state of the MEC server within the DT modelling cycle. To achieve energy and spectrally efficient offloading, we con… Show more

“…This promising technology enables edge intelligence in 6G networks, recognized as a key factor supporting the development of the Industrial Internet of Things (IIoT). This solution could facilitate more effective monitoring and management of critical infrastructures and industrial processes, thereby contributing to increased security levels in industry and IoT sectors [32]. Another interesting solution may be the combination of the IIoT and federated learning (FL), considered promising for enabling Industry 4.0 and beyond.…”

“…Digital twin technology, which creates a virtual replica of the real world in a computerized environment, differs from other simulation technologies by reflecting changes in real-time and allowing AI to analyze big data collected by IoT devices to understand subtle phenomena occurring in the physical world. Long Zhang et al discussed this approach in their support system for industrial IoT scenarios [7], aiming to minimize the total task completion delay across industrial IoT devices. This technology could enhance the performance of log acquisition and recording in IoT environments.…”

“…ICN is a new network architecture designed to avoid the network congestion and response degradation that are expected to occur when mobile and IoT devices communicate at scale. In addition to ICN, research is being conducted to solve these problems using edge computing and Reconfigurable Intelligent Surfaces (RIS) [3,4].…”
