Traffic-Aware Time-Critical Scheduling in Heavily Duty-Cycled IEEE 802.15.4e for an Industrial IoT

In the last few years, the new requirements of the emerging Internet of Thing (IoT) applications could not be satisfied anymore by the traditional IEEE 802.15.4. Thus, they entail the need for additional MAC layer options, enabling channel hopping, sampled listening and able to improve power consumption, resilience to inference, and reliability. The Time Synchronized Channel Hopping (TSCH) protocol is part of the newly defined IEEE 802.15.4e standard and represents the latest generation of highly reliable low-power MAC protocols. In this paper, the authors propose a novel Traffic Aware Scheduling Algorithm (TASA) able to support emerging IoT industrial applications requiring low latency at low duty cycle and power consumption. Their findings are supported by various theoretical and some preliminary simulation results.
