Distributed Bayesian Quickest Change Detection in Sensor Networks via Two-layer Large Deviation Analysis
Di Li, Soummya Kar, Fuad E. Alsaadi +1
We propose a distributed Bayesian quickest change detection algorithm for sensor networks, based on a random gossip inter-sensor communication structure. Without a control or fusio…
Learning-Based Distributed Detection-Estimation in Sensor Networks with Unknown Sensor Defects
Qing Zhou, Di Li, Soummya Kar +3
We consider the problem of distributed estimation of an unknown deterministic scalar parameter (the target signal) in a wireless sensor network (WSN), where each sensor receives a…
Power vs. Spectrum 2-D Sensing in Energy Harvesting Cognitive Radio Networks
Yanyan Zhang, Weijia Han, Di Li +2
Energy harvester based cognitive radio is a promising solution to address the shortage of both spectrum and energy. Since the spectrum access and power consumption patterns are int…
Distributed Kalman Filtering over Massive Data Sets: Analysis Through Large Deviations of Random Riccati Equations
Di Li, Soummya Kar, Jose' M. F. Moura +2
This paper studies the convergence of the estimation error process and the characterization of the corresponding invariant measure in distributed Kalman filtering for potentially u…
