Measurement partitioning and observational equivalence in state estimation
Mohammadreza Doostmohammadian, Usman A. Khan
This letter studies measurement partitioning and equivalence in state estimation based on graph-theoretic principles. We show that a set of critical measurements (required to ensur…
Networked estimation under information constraints
Usman A. Khan, Ali Jadbabaie
In this paper, we study estimation of potentially unstable linear dynamical systems when the observations are distributed over a network. We are interested in scenarios when the in…
Higher Dimensional Consensus: Learning in Large-Scale Networks
Usman A. Khan, Soummya Kar, Jose M. F. Moura
The paper presents higher dimension consensus (HDC) for large-scale networks. HDC generalizes the well-known average-consensus algorithm. It divides the nodes of the large-scale ne…
Distributed Sensor Localization in Random Environments using Minimal Number of Anchor Nodes
Usman A. Khan, Soummya Kar, Jose' M. F. Moura
The paper develops DILOC, a \emph{distributive}, \emph{iterative} algorithm that locates M sensors in , with respect to a minimal number of m+1 anchors with…
Distributing the Kalman Filter for Large-Scale Systems
Usman A. Khan, Jose M. F. Moura
This paper derives a \emph{distributed} Kalman filter to estimate a sparsely connected, large-scale, dimensional, dynamical system monitored by a network of sensors. Local…
