Enhancing Real-Time Data Communication and Security in ConnectedVehicles Using MQTT Protocol

Abstract

The rapid advancement of connected vehicle technology has created a pressing need for efficient, secure, and scalable communication protocols. This paper explores the implementation of the Message Queuing Telemetry Transport (MQTT) protocol to enhance real-time data communication and security in connected vehicles. We examine the unique challenges posed by vehicular networks, including intermittent connectivity, low-latency requirements, and security concerns. The research demonstrates how MQTT's lightweight publish-subscribe model can significantly improve data transmission efficiency and reduce latency in vehicle-to-vehicle (V2V) and vehicle- to-infrastructure (V2I) communications. Our findings indicate that MQTT offers superior
scalability and lower overhead, making it particularly suitable for large-scale connected vehicle networks. Additionally, we address critical security
considerations, proposing enhanced authentication, authorization, and encryption methods tailored for vehicular applications of MQTT. Through
case studies, we illustrate the practical benefits of MQTT in real-world scenarios such as fleet management. This research contributes to the ongoing development of efficient and secure communication systems for the next generation of connected vehicles.
