Cislunar Pursuit-Evasion Game on Periodic and Quasi-Periodic Orbits
Quentin Rommel, Filippos Fotiadis, Cade Armstrong +2
Cislunar spacecraft operate in nonlinear and unstable environments that make defensive maneuver planning difficult. We formulate cislunar spacecraft pursuit and evasion as a zero-s…
Remote ID Spoofing-Aware Trajectory Planning for Small Unmanned Aerial Systems
Jeremiah Webb, Bryce Bjorkman, Abel Diaz Gonzalez +7
This work presents a decentralized, spoofing-aware trajectory planning framework for small unmanned aerial systems operating under Remote Identification (RID) location spoofing att…
Characterizing Opinion Evolution of Networked LLMs
Caleb Probine, Yigit Ege Bayiz, Filippos Fotiadis +3
Large language models (LLMs) increasingly interact with one another in multi-agent systems, from simulations of human discourse to influence operations and fully LLM-driven social…
Noncooperative Coordination via a Trading-based Auction
Jaehan Im, Filippos Fotiadis, Daniel Delahaye +2
Noncooperative multi-agent systems often face coordination challenges due to conflicting preferences among agents. In particular, when agents act in their own self-interest, they m…
Secure Coordination for Vertiport Sequencing in Advanced Air Mobility
Jaehan Im, Filippos Fotiadis, Ufuk Topcu +1
Advanced air mobility operations will require reliable coordination mechanisms for managing dense traffic near vertiports. However, sequencing decisions may become vulnerable when…
Robust Multi-Agent Reinforcement Learning for Small UAS Separation Assurance under GPS Degradation and Spoofing
Alex Zongo, Filippos Fotiadis, Ufuk Topcu +1
We address robust separation assurance for small Unmanned Aircraft Systems (sUAS) under GPS degradation and spoofing via Multi-Agent Reinforcement Learning (MARL). In cooperative s…
