Digital Twin AI for Hyper-Local Wildfire Spread Prediction Using 5G IoT Mesh Networks

Wildfire spread prediction demands hyper-local accuracy at scales unattainable by traditional physics-based models or coarse satellite observations. This paper introduces a novel Digital Twin AI framework leveraging 5G IoT mesh networks to deliver real-time, 10m×10m resolution fire propagation forecasts with 5-60-minute lead times. Deployed across 1,200 self-healing sensor nodes, the system fuses multi-modal environmental data thermal anomalies, 3D winds profiles, dynamic fuel moisture at 100Hz through graph attention networks, feeding physics-informed neural twins synchronized via unscented Kalman filtering. The edge-optimized prediction engine combines convolutional cellular automata with graph neural networks, achieving 42% IoU improvement over FARSITE baselines while executing 8.2ms inference cycles on Jetson Orin NPUs. Federated learning across mesh nodes enables continuous adaptation without compromising operational privacy, while INT4 quantization and RTOS scheduling guarantee sub-10ms end-to-end latency critical for first responder activation. The framework scales linearly to 10K nodes, reduces false alerts by 73%, and maintains 99.999% uptime through dynamic routing around fire-damaged sensors. This work establishes a new paradigm for autonomous wildfire intelligence, transforming reactive response into proactive hyper local containment.
