The Internet of Vehicles (IoV) has emerged as a critical research domain that integrates vehicular networks, Internet of Things (IoT), cloud/edge computing, artificial intelligence, and 5G/6G technologies to enable intelligent transportation systems, autonomous driving, and smart mobility services. Research papers in this field explore diverse areas such as vehicle-to-everything (V2X) communication, secure data sharing, traffic optimization, intelligent routing, edge-assisted computing, blockchain-enabled trust management, and privacy-preserving architectures for connected vehicles. Recent studies also address challenges in real-time decision-making, interoperability, cybersecurity, energy efficiency, and quality of service (QoS) to ensure reliable and scalable IoV deployments. With rapid advancements in AI-driven analytics, federated learning, and zero trust architectures, IoV research continues to play a vital role in shaping the future of smart transportation ecosystems and sustainable urban mobility.
