APPARATUS AND METHOD TO PERFORM SCHEDULING IN INDUSTRIAL INTERNET OF THINGS NETWORK BASED ON TSCH AND RPL

摘要

The present invention relates to an apparatus and a method to perform scheduling in an industrial Internet of things (IoT) network based on time slotted channel hopping (TSCH) and RPL, capable of reducing a delay time and increasing network efficiency by scheduling with small overhead in the TSCH and the RPL based industrial IoT network. According to the present invention, the apparatus comprises: a parent selection management module to determine network join and a link value to select a parent node, and change a parent node; a scheduling message transmission module to transfer a join request message to a root node and to transmit a deallocation request message; a scheduling message reception module to receive the join request message and to receive the deallocation request message and slot information; a scheduling message processing module to perform join request message processing, deallocation request message processing, and slot information processing; a DIO message processing module to receive a DIO message and to update neighboring node information; a scheduling manager module to perform scheduling message reception, scheduling algorithm processing, and slot information transmission; and a slot management module to perform scheduling table management, active slot addition, and active slot removal.;COPYRIGHT KIPO 2018
