Abstract This paper investigates mobility-aware online optimization for digital twin (DT)-assisted task execution in edge computing environments. In such systems, DTs, hosted on edge servers (ESs), require proactive migration to maintain proximity to their mobile physical twin (PT) counterparts. To minimize task response latency under a stringent energy consumption constraint, we jointly optimize three key components: the status data uploading frequency from the PT, the DT migration decisions, and the allocation of computational and communication resources. To address the asynchronous nature of these decisions, we propose a novel two-timescale mobility-aware online optimization (TMO) framework. The TMO… More >
