Edge Augmentation with Controllability Constraints in Directed Laplacian Networks
Waseem Abbas, Mudassir Shabbir, Yasin Yazıcıoglu +1
In this paper, we study the maximum edge augmentation problem in directed Laplacian networks to improve their robustness while preserving lower bounds on their strong structural co…
Interplay Between Resilience and Accuracy in Resilient Vector Consensus in Multi-Agent Networks
Waseem Abbas, Mudassir Shabbir, Jiani Li +1
In this paper, we study the relationship between resilience and accuracy in the resilient distributed multi-dimensional consensus problem. We consider a network of agents, each of…
Strong Structural Controllability of Diffusively Coupled Networks: Comparison of Bounds Based on Distances and Zero Forcing
Yasin Yazicioglu, Mudassir Shabbir, Waseem Abbas +1
We study the strong structural controllability (SSC) of diffusively coupled networks, where the external control inputs are injected to only some nodes, namely the leaders. For suc…
Improving Network Robustness through Edge Augmentation While Preserving Strong Structural Controllability
Waseem Abbas, Mudassir Shabbir, Hassan Jaleel +1
In this paper, we consider a network of agents with Laplacian dynamics, and study the problem of improving network robustness by adding a maximum number of edges within the network…
Resilient Distributed Vector Consensus Using Centerpoints
Waseem Abbas, Mudassir Shabbir, Jiani Li +1
In this paper, we study the resilient vector consensus problem in networks with adversarial agents and improve resilience guarantees of existing algorithms. A common approach to ac…
Resilient Supervisory Control of Autonomous Intersections in the Presence of Sensor Attacks
Amin Ghafouri, Xenofon D. Koutsoukos
Cyber-physical systems (CPS), such as autonomous vehicles crossing an intersection, are vulnerable to cyber-attacks and their safety-critical nature makes them a target for malicio…
Vulnerability of Fixed-Time Control of Signalized Intersections to Cyber-Tampering
Amin Ghafouri, Waseem Abbas, Yevgeniy Vorobeychik +1
Recent experimental studies have shown that traffic management systems are vulnerable to cyber-attacks on sensor data. This paper studies the vulnerability of fixed-time control of…
Sensor placement for fault location identification in water networks: A minimum test cover approach
Lina Sela Perelman, Waseem Abbas, Xenofon Koutsoukos +1
This paper focuses on the optimal sensor placement problem for the identification of pipe failure locations in large-scale urban water systems. The problem involves selecting the m…
Resilient Continuous-Time Consensus in Fractional Robust Networks
Heath J. LeBlanc, Haotian Zhang, Shreyas Sundaram +1
In this paper, we study the continuous-time consensus problem in the presence of adversaries. The networked multi-agent system is modeled as a switched system, where the normal age…
