Title:
DEVICE AND METHOD FOR SCHEDULING IN TSCH AND RPL-BASED INDUSTRIAL IOT NETWORK
Document Type and Number:
WIPO Patent Application WO/2018/080113
Kind Code:
A2
Abstract:
The present invention relates to a device and method for scheduling in a TSCH and RPL-based industrial IoT network, wherein delay time is reduced and network efficiency is increased due to a small scheduling overhead in a TSCH and RPL-based industrial IoT network. The device includes: a parent selection management module which selects a parent node by determining network participation and determining rank value, and changes the parent node; a scheduling message transmission module for delivering a join request message to a root node, and transmitting a deallocation request message; a scheduling message receiving module for receiving the join request message, and receiving the deallocation message, and slot information; a scheduling message processing module for performing a join request message process, a deallocation request message process, and a slot information process; a DIO message processing module for receiving a DIO message and updating neighbor node information; a scheduling manager module for performing scheduling message reception, a scheduling algorithm process, and slot information transmission; and a slot management module for performing scheduling table management, active slot addition, and active slot deletion.
