Abstract

IETF 6TiSCH is emerging as a promised open-standard for industrial internet of things (IIoT). With employing Time Slotted Channel Hopping (TSCH) mode, 6TiSCH can meet critical requirements in the industrial sector such as reliability, determinism and real time. 6TiSCH is currently focusing on monitoring applications. This paper considers its applicability in industrial control, in which sensor and actuator are coexistent in the network. We first investigate applicable wireless sensor-actuator models based on 6TiSCH. Then, an efficient data transmission scheme between sensor and actuator is proposed. Through simulation results, we show that our solution achieves a significant improvement in terms of end-to-end latency and energy consumption compared to the bursty transmission in the 6TiSCH networks.
