TSCH TSCH METHOD FOR SUPPORTING MULTIPATH TRANSMISSION FOR TSCH MAC ENVIRONMENTS NODE APPARATUS IN A MULTIPATH TRANSMITTING TSCH MAC ENVIRONMENT

摘要

The present invention relates to a method for improving reliability of paths and reducing transmission delay by distributing traffic by using a multipath technique rather than a single path in a communication environment using TSCH, a schedule for forwarding traffic A schedule setting unit that sets the same as a plurality of parent node devices, a traffic assignment unit that sets a traffic rate using statistical information received from the parent node device, and an ASN (Absolute Slot) of a plurality of parent node devices in response to the traffic rate Number) slot management unit for setting, and a communication unit for transmitting ASN and traffic to a plurality of parent node devices in response to a schedule.
