Optimizing J1939 Messages Response Time by Using Evolutionary Algorithms 2009-36-0294

The J1939 protocol is a SAE recommended practice for CAN in commercial vehicles and others [3]. Due to electronics increasing, the current vehicle networks require upgrading and optimization. Some strategies must be implemented in order to allow more messages without harm the current messages time restrictions. These strategies must focus on optimization. One group of evolutionary algorithms commonly used in Optimization problems are the Genetic Algorithms. This paper proposes the usage of genetic algorithms to optimize the message response time in a set of J1939 messages over CAN. A mathematical model for temporal calculations is presented as default, representing the current condition and the problem characterization. The application of the concept of Genetics characteristics represents the current condition. The implementation of the algorithm is showed and also the comparative results.
