Resumo

This paper presents a systematic scheduling method to guarantee the end-to-end constraints including precedence constraints of tasks, messages and both. The presented systematic method is the integrated or joint one of both tasks executed in each node and messages transmitted via the network. The presented method is designed to apply to the general distributed control system that has multiple loops and in a single loop has sensor nodes with multiple sensors, actuator nodes with multiple actuators, controller nodes with multiple tasks, and several constraints. The worst-case response time is analysed using the proposed method.
