Most Wi-Fi sensing models are trained on simulated data built by adding noise to recorded channel estimates. We tested that assumption on six commodity receivers and found it breaks: the receiver's automatic gain control compresses the signal in ways no additive noise can reproduce. Our answer is MQTC, a measurement-calibrated model combining quantile mapping, temporal filtering, and copula-based reordering, which cuts amplitude error 8-fold and closes 89% of the fidelity gap. Classifiers trained on MQTC data recover 93% of real-world jamming-detection performance, while noise-trained ones remain near random.

A jamming attack can silence an entire wireless factory floor. CITADEL detects and classifies jamming using only Channel State Information, a signal that commodity IIoT devices already produce for free, and it recognizes attacks it has never been trained on. Across 6 known and 15 zero-day attack scenarios it reaches 100% and 97.1% detection at a 0.4% false-positive rate, resists adversarial evasion, and runs end-to-end in 14.2 ms on an edge GPU, outperforming eight baselines.

This paper is the roadmap of my doctoral thesis: a lightweight, multi-layer, ML-based security framework for the Industrial IoT. It builds on the Tm-IIoT trust model and the Hybrid IIoT architecture, adds the Trust Convergence Acceleration approach for up to 28.6% faster trust decisions on degraded networks, and extends toward physical-layer threat detection and resilience against adversarial ML, aiming at real deployments on affordable, open-source hardware rather than simulation alone.

Trust scores are only useful once they converge, and on real networks with fluctuating quality that can take far too long. TCA (Trust Convergence Acceleration) puts a Random Forest in the loop: it predicts how long convergence will take and adapts the trust model's transition probabilities on the fly. Under realistic Wi-Fi 6 conditions, TCA cuts trust-convergence time by up to 28.6% in challenging conditions while improving accuracy against malicious nodes.

Drones in 6G networks need ultra-reliable, low-latency links while moving fast through three dimensions. We tackle spectrum allocation for aerial users in user-centric cell-free massive MIMO: a deep reinforcement learning agent (DDPG) assigns frequency subbands while balancing interference, spectral efficiency, and fairness under strict bandwidth limits. The learned policy adapts to altitude-varying conditions better than two bio-inspired optimizers (BGWO and BMFO) and shows the architecture can meet 6G performance targets for aerial networks.

FITNESS is a national research initiative funded by the French Research Agency (ANR) under France 2030, asking what still stands between the IoT and large-scale adoption. This white paper presents the project's vision and first findings on three fronts: IoT architecture and interoperability, the place of artificial intelligence in IoT, and energy efficiency, validated against concrete industrial use cases on the road to a secure, efficient, and interoperable IoT ecosystem.
