Data Exchange with the MQTT Protocol: Dynamic Bridge Approach

The interconnection of our vehicles increases the efficiency and responsiveness of driving systems and passengers' comfort. Knowing this specificity, systems must be able to exploit an incalculable amount of more or less essential data. This data requires a particular organisation and many existing protocols allow its hierarchy, its archival in an orderly way or its simplified propagation within the network. This problematic is the same as the one encountered in the field of Internet of Things (IoT) suitable for vehicles. This paper focuses on exchanges between vehicle groups with IoT linked by Message Queue Telemetry Transport (MQTT) protocol and their hot connectivity to ensure the highest availability of data in the network.
