Distributed Average Consensus in Wireless Multi-Agent Systems with Over-the-Air Aggregation
Themistoklis Charalambous, Zheng Chen, Christoforos N. Hadjicostis
In this paper, we address the average consensus problem of multi-agent systems over wireless networks. We propose a distributed average consensus algorithm by invoking the concept…
Decentralized State Estimation and Opacity Verification Based on Partially Ordered Observation Sequences
Dajiang Sun, Christoforos N. Hadjicostis, Zhiwu Li
In this paper, we investigate state estimation and opacity verification problems within a decentralized observation architecture. Specifically, we consider a discrete event system…
Average Consensus over Directed Networks in Open Multi-Agent Systems with Acknowledgement Feedback
Evagoras Makridis, Andreas Grammenos, Gabriele Oliva +3
In this paper, we address the distributed average consensus problem over directed networks in open multi-agent systems (OMAS), where the stability of the network is disrupted by fr…
Global and Local Error-Tolerant Decentralized State Estimation under Partially Ordered Observations
Dajiang Sun, Christoforos N. Hadjicostis, Zhiwu Li
We investigate decentralized state estimation for a discrete event system in a setting where the information received at a coordinator may be corrupted or tampered by a malicious a…
Distributed Optimization for Quadratic Cost Functions over Large-Scale Networks with Quantized Communication and Finite-Time Convergence
Apostolos I. Rikos, Andreas Grammenos, Evangelia Kalyvianaki +3
We propose two distributed iterative algorithms that can be used to solve, in finite time, the distributed optimization problem over quadratic local cost functions in large-scale n…
Distributed Computation of Exact Average Degree and Network Size in Finite Number of Steps under Quantized Communication
Apostolos I. Rikos, Themistoklis Charalambous, Christoforos N. Hadjicostis +1
We consider the problems of computing the average degree and the size of a given network in a distributed fashion under quantized communication. We present two distributed algorith…
