This paper describes a scheduling method of wireless control networks for factory automation using IEEE 802.15.4 networks. The superframe of IEEE 802.15.4 is used for the transmission of real-time mixed data for wireless control systems. The schedulability of real-time data is defined, and scheduling algorithms are proposed for the efficient transmission of real-time mixed traffic. Simulation results show enhancements in the average network utilization and packet drop rate for real-time data.
