Networked Control System Under Controller-Actuator Channel Jamming
Chen Quan, Geethu Joseph, Gourab Ghatak
Wireless channels in the networked control systems are vulnerable to intentional interference, such as jamming attacks. This paper investigates jamming attacks on the wireless cont…
Information Age-Controllability Trade-offs in Communication-Constrained Networks
Songita Das, Gourab Ghatak, Chen Quan +1
We investigate the trade-off between controllability, channel access, and age-related performance in a wireless network of control systems. Controllers share a random-access channe…
An Energy-efficient Ordered Transmission-based Sequential Estimation
Chen Quan, Geethu Joseph, Nitin Jonathan Myers
Estimation problems in wireless sensor networks typically involve gathering and processing data from distributed sensors to infer the state of an environment at the fusion center.…
Channel Access Strategies for Control-Communication Co-Designed Networks
Gourab Ghatak, Geethu Joseph, Chen Quan
We develop a framework for communication-control co-design in a wireless networked control system with multiple geographically separated controllers and controlled systems, modeled…
