Confidence Boosts Trust-Based Resilience in Cooperative Multi-Robot Systems
Luca Ballotta, Áron Vékássy, Stephanie Gil +1
Wireless communication-based multi-robot systems open the door to cyberattacks that can disrupt safety and performance of collaborative robots. The physical channel supporting inte…
Multi-Agent Trustworthy Consensus under Random Dynamic Attacks
Orhan Eren Akgün, Sarper Aydın, Stephanie Gil +1
In this work, we study the consensus problem in which legitimate agents send their values over an undirected communication network in the presence of an unknown subset of malicious…
Friedkin-Johnsen Model with Diminishing Competition
Luca Ballotta, Áron Vékássy, Stephanie Gil +1
This letter studies the Friedkin-Johnsen (FJ) model with diminishing competition, or stubbornness. The original FJ model assumes that each agent assigns a constant competition weig…
Fast Distributed Optimization over Directed Graphs under Malicious Attacks using Trust
Arif Kerem Dayı, Orhan Eren Akgün, Stephanie Gil +2
In this work, we introduce the Resilient Projected Push-Pull (RP3) algorithm designed for distributed optimization in multi-agent cyber-physical systems with directed communication…
Multi-Agent Resilient Consensus under Intermittent Faulty and Malicious Transmissions (Extended Version)
Sarper Aydın, Orhan Eren Akgün, Stephanie Gil +1
In this work, we consider the consensus problem in which legitimate agents share their values over an undirected communication network in the presence of malicious or faulty agents…
How Physicality Enables Trust: A New Era of Trust-Centered Cyberphysical Systems
Stephanie Gil, Michal Yemini, Arsenia Chorti +3
Multi-agent cyberphysical systems enable new capabilities in efficiency, resilience, and security. The unique characteristics of these systems prompt a reevaluation of their securi…
Projected Push-Pull For Distributed Constrained Optimization Over Time-Varying Directed Graphs (extended version)
Orhan Eren Akgün, Arif Kerem Dayı, Stephanie Gil +1
We introduce the Projected Push-Pull algorithm that enables multiple agents to solve a distributed constrained optimization problem with private cost functions and global constrain…
Exploiting Trust for Resilient Hypothesis Testing with Malicious Robots (evolved version)
Matthew Cavorsi, Orhan Eren Akgün, Michal Yemini +2
We develop a resilient binary hypothesis testing framework for decision making in adversarial multi-robot crowdsensing tasks. This framework exploits stochastic trust observations…
