This paper 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 the integrated one considering both tasks executed in each node and messages transmitted via the network and is designed to apply to the 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.
