Abstract :
FlexRay is an automotive communication protocol that combines the comprehensive time-triggered paradigm with an adaptive phase that is more suitable for event-based communication. We study optimization of average response times by assigning priorities and frame identifiers to tasks and messages. Our optimization approach is based on immune genetic algorithms, where in addition to the crossover and mutation operators, we use a vaccination operator that results in considerable improvements in optimization time and quality.
