Research and Optimization on Media Access Control Delay of CAN

Article Preview

Abstract:

With data quantity increasing dramatically and signal transmission period becoming more and more fast, the media access control delay has proved to be one of the main influence factors of CAN network real-time. Firstly, an equivalent numerical simulation model of CAN bus network is built to derivate the mathematical expression of media access control delay. Secondly, optimization measures are further proposed to improve the data communication real-time. At last, the optimization measures tested by experiments are proved to be correct and effective.
