Wireless Network Design for Emerging IIoT Applications: Reference Framework and Use Cases

April 16, 2019
Author(s)
Yongkang Liu, Mohamed T. Hany, Kang B. Lee, Lotfi Benmohamed, Richard Candell
In this paper we propose a framework that allows a designer to assess various physical and cyber factors involved in determining the performance of a wireless use case as well as evaluate their performance impacts in search for a design that leads to an

Channel Characterization and Delay Optimization for Industrial Wireless Control Systems

March 4, 2019
Author(s)
Xiaolin Jiang, Zhibo Pang, Rick Candell, Dacfey Dzung, Michele Luvisotto, Carlo Fischione
Wireless communication is gaining popularity in industry for its simple deployment, mobility and low cost. Ultra low latency and high reliability requirements of mission critical industrial applications are highly demanding for wireless communication, and

Model-based Cosimulation for Industrial Wireless Networks

June 15, 2018
Author(s)
Ging Jeng, Honglei Li, Yanzhou Liu, Yongkang Liu, Mohamed Hany, Rick Candell, Shuvra Bhattacharyya
Wireless communications technology has the potential to provide major benefits in lowering the cost and increasing the efficiency of factory automation (FA) systems. However, design of FA systems that employ wireless networks involves stringent constraints

Dimensioning Wireless Use Cases in Industrial Internet of Things

June 12, 2018
Author(s)
Yongkang Liu, Rick Candell, Mohamed Hany, Lotfi Benmohamed
Industrial wireless is becoming increasingly needed in the Industrial Internet of Things (IIoT) for carrying mission-critical data to leverage the visibility, control, and safety of industrial environments. In this paper we propose a framework that

Guide to Industrial Wireless Systems Deployments

May 21, 2018
Author(s)
Richard Candell, Mohamed T. Hany, Kang B. Lee, Yongkang Liu, Jeanne T. Quimby, Catherine A. Remley
This document is intended to be a practical guide used by engineers and managers facilitating them to go through the process of defining the objectives of their wireless systems and examining the environments where the wireless systems are to be deployed

Fading due to static and dynamic features in a factory environment on wireless channels

April 20, 2018
Author(s)
Alexandra Curtin, David R. Novotny, Richard Candell, Galen H. Koepke, Peter B. Papazian, Jeanne T. Quimby, Catherine A. Remley
Channel sounding of dense or complex environments such as industrial or factory spaces is an important piece to the puzzle of increasing the deployment of current and next-generation wireless technologies. The deployment of machine--to-machine or vehicle

A Survey of Physics-Based Attack Detection in Cyber-Physical Systems

March 30, 2018
Author(s)
Jairo Giraldo, David Urbina, Alvaro Cardenas, Junia Valente, Mustafa Faisal, Justin Ruths, Niles O. Tippenhauer, Heinrik Sandberg, Rick Candell
Monitoring the "physics" of cyber-physical systems to detect attacks is a growing area of research. In its basic form a security monitor creates time-series models of sensor readings for an industrial control system and identifies anomalies in these
