document: Assignment of periods and priorities of messages and tasks in distributed control systems Presents a task and message-based scheduling method to guarantee the given end-to-end constraints including precedence constraints , time constraints , and period and priority of task and message . The method is an integrated one considering both tasks executed in each node and messages transmitted via the network and is designed to apply to a general distributed control system that has multiple loops and a single loop has sensor nodes with multiple sensors , actuator nodes with multiple actuators , controller nodes with multiple tasks , and several types of constraints . The assigning method of the optimal period and priority of task and message is proposed , using the presented task and message-based scheduling method
