Ryan Brummet, Md Kowsar Hossain, Octav Chipara, Ted Herman, David E., Steward

TL;DR
Recorp introduces receiver-oriented policies for industrial wireless networks, combining offline synthesis and runtime adaptation to ensure predictable performance, high reliability, and reduced latency in IIoT systems.
Contribution
This paper presents Recorp, a novel receiver-oriented policy framework that improves predictability and performance in industrial wireless networks through combined offline and online strategies.
Findings
Median increase of 50% to 142% in real-time capacity
Median decrease of 27% to 70% in worst-case latency
Policies meet 99% end-to-end reliability threshold
Abstract
Future Industrial Internet-of-Things (IIoT) systems will require wireless solutions to connect sensors, actuators, and controllers as part of high data rate feedback-control loops over real-time flows. A key challenge in such networks is to provide predictable performance and adaptability in response to link quality variations. We address this challenge by developing RECeiver ORiented Policies (Recorp), which leverages the stability of IIoT workloads by combining offline policy synthesis and run-time adaptation. Compared to schedules that service a single flow in a slot, Recorp policies share slots among multiple flows by assigning a coordinator and a list of flows that may be serviced in the same slot. At run-time, the coordinator will execute one of the flows depending on which flows the coordinator has already received. A salient feature of Recorp is that it provides predictable…
