• Securing Time Integrity in Energy IoT Against Clock Drift and Y2K38 Failures

  Saeid Jamshidi, Omar Abdul Wahab, Rolando Herrero, Foutse Khomh · 25 June 2026

  The integrity of time in distributed Internet of Things (IoT) devices is crucial for reliable operation in energy cyber-physical systems, such as smart grids and microgrids. However, IoT systems are vulnerable to clock drift, time-synchronization manipulation, and timestamp discontinuities, such as …

• TWIST: Closed-Loop token Synchronization for Application-Aware Wireless Digital Twins

  Sige Liu, Kezhi Wang · 27 May 2026

  Wireless digital twins require repeated synchronization between a time-evolving physical scene and its digital counterpart under limited and time-varying communication resources. For perception-centric twins, pixel-domain transmission or uniformly protected bitstreams can be mismatched to the semant…

• GO-GenZip: Goal-Oriented Generative Sampling and Hybrid Compression

  Pietro Talli, Qi Liao, Alessandro Lieto, Parijat Bhattacharjee, Federico Chiariotti, Andrea Zanella · 23 March 2026

  Current network data telemetry pipelines consist of massive streams of fine-grained Key Performance Indicators (KPIs) from multiple distributed sources towards central aggregators, making data storage, transmission, and real-time analysis increasingly unsustainable. This work presents a generative A…

• Securing Time in Energy IoT: A Clock-Dynamics-Aware Spatio-Temporal Graph Attention Network for Clock Drift Attacks and Y2K38 Failures

  Saeid Jamshidi, Omar Abdul Wahab, Rolando Herrero, Foutse Khomh · 2 February 2026

  The integrity of time in distributed Internet of Things (IoT) devices is crucial for reliable operation in energy cyber-physical systems, such as smart grids and microgrids. However, IoT systems are vulnerable to clock drift, time-synchronization manipulation, and timestamp discontinuities, such as …

• Q-Learning-Based Time-Critical Data Aggregation Scheduling in IoT

  Van-Vi Vo, Tien-Dung Nguyen, Duc-Tai Le, Hyunseung Choo · 25 November 2025

  Time-critical data aggregation in Internet of Things (IoT) networks demands efficient, collision-free scheduling to minimize latency for applications like smart cities and industrial automation. Traditional heuristic methods, with two-phase tree construction and scheduling, often suffer from high co…

• Real-Time Inference for Distributed Multimodal Systems under Communication Delay Uncertainty

  Victor Croisfelt, Jo\~ao Henrique Inacio de Souza, Shashi Raj Pandey, Beatriz Soret, Petar Popovski · 21 November 2025

  Connected cyber-physical systems perform inference based on real-time inputs from multiple data streams. Uncertain communication delays across data streams challenge the temporal flow of the inference process. State-of-the-art (SotA) non-blocking inference methods rely on a reference-modality paradi…
