Distributed Detection and Mitigation of Biasing Attacks over Multi-Agent Networks
Mohammadreza Doostmohammadian, Houman Zarrabi, Hamid R. Rabiee +2
This paper proposes a distributed attack detection and mitigation technique based on distributed estimation over a multi-agent network, where the agents take partial system measure…
Analysis of Contractions in System Graphs: Application to State Estimation
Mohammadreza Doostmohammadian, Themistoklis Charalambous, Miadreza Shafie-khah +2
Observability and estimation are closely tied to the system structure, which can be visualized as a system graph--a graph that captures the inter-dependencies within the state vari…
On the Observability and Controllability of Large-Scale IoT Networks: Reducing Number of Unmatched Nodes via Link Addition
Mohammadreza Doostmohammadian, Hamid R. Rabiee
In this paper, we study large-scale networks in terms of observability and controllability. In particular, we compare the number of unmatched nodes in two main types of Scale-Free…
Cyber-Social Systems: Modeling, Inference, and Optimal Design
Mohammadreza Doostmohammadian, Hamid R. Rabiee, Usman A. Khan
This paper models the cyber-social system as a cyber-network of agents monitoring states of individuals in a social network. The state of each individual is represented by a social…
Structural cost-optimal design of sensor networks for distributed estimation
Mohammadreza Doostmohammadian, Hamid R. Rabiee, Usman A. Khan
In this letter we discuss cost optimization of sensor networks monitoring structurally full-rank systems under distributed observability constraint. Using structured systems theory…
Distributed Estimation Recovery under Sensor Failure
Mohammadreza Doostmohammadian, Hamid R. Rabiee, Houman Zarrabi +1
Single time-scale distributed estimation of dynamic systems via a network of sensors/estimators is addressed in this letter. In single time-scale distributed estimation, the two fu…
Observational Equivalence in System Estimation: Contractions in Complex Networks
Mohammadreza Doostmohammadian, Hamid R. Rabiee, Houman Zarrabi +1
Observability of complex systems/networks is the focus of this paper, which is shown to be closely related to the concept of contraction. Indeed, for observable network tracking it…
Sensor Selection Cost Optimization for Tracking Structurally Cyclic Systems: a P-Order Solution
Mohammadreza Doostmohammadian, Houman Zarrabi, Hamid R. Rabiee
Measurements and sensing implementations impose certain cost in sensor networks. The sensor selection cost optimization is the problem of minimizing the sensing cost of monitoring…
