Abstract

The main contribution of this manuscript is an innovative framework for integrating Artificial Intelligence (AI) in 6G wireless systems. With increased complexity, including bursty traffic, network complexity, and dynamic variability, there is a need for intelligence. This study develops and validates an AI-driven approach that enhances network performance through quantum communication decoding, beamforming, and decentralized edge processing. Kalman filtering predictive models are used to estimate variable channel conditions in a Terahertz (THz) network to support beamforming to optimize beamforming. Artificial Intelligence exploits smart reflective surfaces (IRS) strengthening signals and improving their coverage. Also, strong security of Quantum Key Distribution (QKD) protocols due to AI enhanced error correction technology, and rapid, yet privacy information conducting at edge nodes due to decentralised processing through federated learning are examples of enhanced capabilities. Extensive ns-3 simulations across 100 independent runs validate the framework's effectiveness and prove the system in practical 6G deployment scenarios including THz links, IRS component and edge nodes. The simulation results demonstrate that the proposed framework achieves superior performance compared to conventional approaches, with statistical validation across multiple deployment scenarios. The system decreases latency by 30%, and adds 25% to spectral efficiency. In bursty traffic, the energy…
