The Internet of Vehicles represents a connected ecosystem where vehicles, infrastructure, and users communicate in real time to enable intelligent transportation. Connected cars rely on advanced communication technologies to exchange data, improving safety, efficiency, and user experience. In this environment, MQTT stands out as a highly suitable protocol due to its lightweight, publish-subscribe design and ability to operate efficiently in low-bandwidth and unstable network conditions. It enables reliable, low-latency communication between vehicles and cloud systems, supporting scalable data exchange. This makes MQTT a key enabler for building responsive, efficient, and interconnected smart mobility solutions.
