Resource Allocation for NOMA-based LPWA Networks Powered by Energy Harvesting
Fatma Benkhelifa, Julie A. McCann
In this paper, we explore perpetual, scalable, Low-powered Wide-area networks (LPWA). Specifically we focus on the uplink transmissions of non-orthogonal multiple access (NOMA)-bas…
Dataset: LoED: The LoRaWAN at the Edge Dataset
Laksh Bhatia, Michael Breza, Ramona Marfievici +1
This paper presents the LoRaWAN at the Edge Dataset (LoED), an open LoRaWAN packet dataset collected at gateways. Real-world LoRaWAN datasets are important for repeatable sensor-ne…
Spatiotemporal Modelling of Multi-Gateway LoRa Networks with Imperfect SF Orthogonality
Yathreb Bouazizi, Fatma Benkhelifa, Julie McCann
Meticulous modelling and performance analysis of Low-Power Wide-Area (LPWA) networks are essential for large scale dense Internet-of-Things (IoT) deployments. As Long Range (LoRa)…
Control Communication Co-Design for Wide Area Cyber-Physical Systems
Laksh Bhatia, Ivana Tomić, Anqi Fu +2
Wide Area Cyber-Physical Systems (WA-CPSs) are a class of control systems that integrate low-powered sensors, heterogeneous actuators and computer controllers into large infrastruc…
Contact-Aware Opportunistic Data Forwarding in Disconnected LoRaWAN Mobile Networks
Po-Yu Chen, Laksh Bhatia, Roman Kolcun +2
LoRaWAN is one of the leading Low Power Wide Area Network (LPWAN) architectures. It was originally designed for systems consisting of static sensor or Internet of Things (IoT) devi…
The Limits of LoRaWAN in Event-Triggered Wireless Networked Control Systems
Ivana Tomić, Laksh Bhatia, Michael J. Breza +1
Wireless sensors and actuators offer benefits to large industrial control systems. The absence of wires for communication reduces the deployment cost, maintenance effort, and provi…
The Separator, a Two-Phase Oil and Water Gravity CPS Separator Testbed
Michael Breza, Laksh Bhatia, Ivana Tomic +4
Industrial Control Systems (ICS) are evolving with advances in new technology. The addition of wireless sensors and actuators and new control techniques means that engineering prac…
