Abstract

Urban Internet of Thing (IoT) networks face severe reliability threats from diverse wireless interference, including jamming and spoofing, which are difficult to detect and localize in multipath-rich environments. Existing schemes often suffer from high false alarms, poor generalization, and low localization accuracy. This article presents an end–edge–cloud interference detection and localization framework integrating zero-shot detection, game-theoretic collaborative sensing, and GNN-based localization. Experiments on a city-scale prototype show that the system achieves 98.5% detection accuracy with recall of 96.7%, while reducing false alarms to 3.2%. The proposed graph neural network (GNN) reduces median localization error to 12.3 m, significantly outperforming baseline methods. Furthermore, the architecture reduces energy consumption by nearly 40% compared with cloud-only designs and maintains end-to-end latency under 120 ms. These results demonstrate that the proposed system enables robust, real-time interference awareness for large-scale IoT deployments, paving the way toward resilient 6G smart cities.

Locality-Preserving Graph Laplacian Manifold Learning Based Model Predictive Control for Three-Phase Inverters

This article presents a model predictive control (MPC) strategy for three-phase inverters based on locality preserving projections (LPPs). Unlike conventional machine learning–based MPC approaches that rely on predefined or high-dimensional input features, the proposed LPP-MPC automatically extracts compact, informative representations by preserving the data’s intrinsic geometric structure. This dimensionality reduction enables fast linear control-law evaluation with computational complexity O(1), making the controller well-suited for real-time implementation. Experimental results demonstrate that the LPP-MPC achieves lower total harmonic distortion (THD) and reduced tracking error compared to quadratic-programming MPC under both linear and nonlinear load conditions, and the proposed controller maintains consistently lower THD throughout load transients than other methods such as two-degree-of-freedom MPC. Compared to existing model-free MPC and deep learning neural network, the LPP-MPC has the lowest THD and root mean square error with the least computational time owing to its efficient linear structure and strong generalization capability.
