Abstract:

In order to improve the reliability of the multifunction vehicle bus (MVB) network system, a method of twomode hot redundancy was adopted to design a model of redundancy ring network for MVB, and proposed a corresponding media redundancy protocol MRPM. To analyze the reliability of MVB redundant ring network, OMNeT++ simulation platform was used to establish the model of MVB redundancy ring network. The results show that when the MVB redundant ring network fails, the MRPM can switch to the monitor bus in reliable and realtime, making the rebliability of the MVB network system improved effectively.

Key words: multifunction vehicle bus (MVB), redundancy, media redundancy protocol, reliability
