Communications Survival Strategies for Industrial Wireless Control

Industrial wireless control systems are mainly designed on the premise of time-sensitive ultra-reliable low-latency communications (URLLC). With introduction survival time to quality service requirements such systems, design paradigm has evolved from typical link reliability (i.e., minimizing packet error rate), availability, that is, chance burst errors, which can cause loss communication for longer than time. In this article, we address implications evolution and present a set strategies guarantee end-to-end dependable industrial control. To ensure transmissions divided into normal modes. The presented include scheduling adaptation target differences between these modes operation, traffic prioritization enhance availability users in mode, more efficient multi-node, multi-path, multi-carrier techniques.
