Abstract

Disclosed is a link-based autonomous cell scheduling device including: a routing information manager that records and manages information on a node's preferred parent node and child nodes in a routing information table; a slot frame manager that generates and modifies a number of slot frames by referring to routing information in the routing information table, packet queue information, and transmission/reception result information; a slot frame schedule determiner that integrates a number of slot frames to generate one integrated slot frame corresponding to a global slot frame size and record the same in an integrated slot frame table, by referring to a link unicast slot frame table, a broadcast slot frame table, and an EB slot frame table; and a TSCH MAC layer driver that operates after checking for a cell assigned to the integrated slot frame by referring to the integrated slot frame table at the TSCH MAC layer.
