Wireless low-power communication technologies play a vital role in building Industrial Internet of Things (IIoT) systems. The 6TiSCH layer is being developed for IIoT applications to use IPv6 upper stack over IEEE 802.15.4e TSCH MAC. 6TiSCH layer defines the scheduling scheme to achieve stringent industrial requirements and QoS advancement. This paper proposes a novel 6TiSCH traffic-aware autonomous scheduling technique for the IIoT network. In this technique, the schedule is created as per the traffic condition at the node, reducing the packet loss. It divides the slotframe into a number of segments and allocates a consecutive segment for the node as per its hop distance from the root. Supplementary cells are allocated to the nodes that are close to the root as these nodes have more traffic than the other nodes in the network. The proposed technique outperforms by improving the Packet Delivery Ratio (PDR) and reducing end-to-end delay compared to other scheduling techniques. The result shows that PDR is improved up to 23% and reduces delay up to 37%. © 2022 Informa UK Limited, trading as Taylor & Francis Group.
