Goal-Oriented Semantic Communication for Distributed ISAC-Enabled Vehicle Coordination
Wenjie Liu, Yansha Deng
The paper proposes a goal‑oriented semantic communication framework that jointly decides when and what sensing and control signals to transmit for vehicle coordination at unsignali…
Safety-aware Goal-oriented Semantic Sensing, Communication, and Control for Robotics
Wenchao Wu, Shutong Chen, Wenjie Liu +3
Wirelessly-connected robotic systems empower robots with real-time intelligence by leveraging remote computing resources for decision-making. However, the data exchange between rob…
Goal-Oriented Semantic Communication for ISAC-Enabled Robotic Obstacle Avoidance
Wenjie Liu, Yansha Deng, Henk Wymeersch
We investigate an integrated sensing and communication (ISAC)-enabled BS for the unmanned aerial vehicle (UAV) obstacle avoidance task, and propose a goal-oriented semantic communi…
Coordinated Position Falsification Attacks and Countermeasures for Location-Based Services
Wenjie Liu, Panos Papadimitratos
With the rise of location-based service (LBS) applications that rely on terrestrial and satellite infrastructures (e.g., GNSS and crowd-sourced Wi-Fi, Bluetooth, cellular, and IP d…
GNSS Spoofing Detection Based on Opportunistic Position Information
Wenjie Liu, Panos Papadimitratos
The limited or no protection for civilian Global Navigation Satellite System (GNSS) signals makes spoofing attacks relatively easy. With modern mobile devices often featuring netwo…
Guardian Positioning System (GPS) for Location Based Services
Wenjie Liu, Panos Papadimitratos
Location-based service (LBS) applications proliferate and support transportation, entertainment, and more. Modern mobile platforms, with smartphones being a prominent example, rely…
