Building Network Digital Twins Part II: Real-Time Adaptive PID for Enhanced State Synchronization
For network operators, this work provides a method to improve NDT synchronization in heterogeneous mobile networks, but the improvement is incremental.
The paper addresses real-time state synchronization in Network Digital Twins (NDTs) for dynamic mobile networks. The proposed adaptive PID controller improves synchronization, with results showing enhanced real-time traffic synchronization.
As we evolve towards more heterogeneous and cutting-edge mobile networks, Network Digital Twins (NDTs) are proving to be a promising paradigm in solving challenges faced by network operators, as they give a possibility of replicating the physical network operations and testing scenarios separately without interfering with the live network. However, with mobile networks becoming increasingly dynamic and heterogeneous due to massive device connectivity, replicating traffic and having NDTs synchronized in real-time with the physical network remains a challenge, thus necessitating the need to develop real-time adaptive mechanisms to bridge this gap. In this part II of our work, we implement a novel framework that integrates an adaptive Proportional-Integral-Derivative (PID) controller to dynamically improve synchronization. Additionally, through an interactive user interface, results of our enhanced approach demonstrate an improvement in real-time traffic synchronization.
