Task Scheduling Scheme for Maintaining Freshness in Digital Twin Systems

Key Points

• The aim is to propose a scheduling scheme that ensures high freshness of digital objects in digital twin systems despite limited computing resources.
• Developed an algorithm that dynamically adjusts update times based on real-time freshness calculations.
• Simulated various scenarios to evaluate the effectiveness of the scheduling approach.
• Emphasized maintaining freshness over task processing rates.
• The proposed scheme effectively maintains required freshness levels by rejecting some tasks.
• Simulation results indicate a significant improvement in freshness compared to traditional task scheduling methods.
