Abstract

In this paper we propose an event-triggered communication protocol with dynamic priority setting for high-integrity systems. The dynamic priority scheduling involves two components: a component based on message history, and a static identifier. In order to investigate the characteristics of the proposed protocol, the worst case performance is analysed and simulation experiments are conducted. The results show that an upper bound on the message delay time can be established with this approach.
