摘要
Disclosed are a scheduling apparatus and method using a virtual slotframe in an industrial wireless sensor network in which devices on the network generate schedules that are efficient with regard to data traffic having various cycles by performing scheduling in a distributed manner through a virtual slotframe scheme, the scheduling apparatus and method including a packet classifier configured to manage, in a list, a point in time when a packet was generated by referring to a packet transmission record, a transmission record analyzer configured to analyze a traffic pattern on the basis of a list indicating the point in time when the packet was generated, a virtual slotframe schedule generation manager configured to generate a virtual slotframe schedule according to the traffic pattern when the traffic pattern is classified, and a schedule converter and aggregator configured to perform a conversion and an aggregation for a direct link schedule to be used for TSCH (Time Slotted Channel Hopping) operation.
