The Internet of vehicles (IoV) is a newly emerged wave that converges Internet of things (IoT) into vehicular networks to benefit\nfrom ubiquitous Internet connectivity. Despite various research efforts, vehicular networks are still striving to achieve higher data\nrate, seamless connectivity, scalability, security, and improved quality of service, which are the key enablers for IoV. It becomes\neven more critical to investigate novel design architectures to accomplish efficient and reliable data forwarding when it comes to\nhandling the emergency communication infrastructure in the presence of natural epidemics. The article proposes a heterogeneous\nnetwork architecture incorporating multiple wireless interfaces (e.g., wireless access in vehicular environment (WAVE), longrange\nwireless fidelity (WiFi), and fourth generation/long-term evolution (4G/LTE)) installed on the on-board units, exploiting\nthe radio over fiber approach to establish a context-aware network connectivity. This heterogeneous network architecture attempts\nto meet the requirements of pervasive connectivity for vehicular ad hoc networks (VANETs) to make them scalable and\nadaptable for IoV supporting a range of emergency services. The architecture employs the Best Interface Selection (BIS) algorithm\nto always ensure reliable communication through the best available wireless interface to support seamless connectivity required\nfor efficient data forwarding in vehicle to infrastructure (V2I) communication successfully avoiding the single point of failure.\nMoreover, the simulation results clearly argue about the suitability of the proposed architecture in IoV environment coping with\ndifferent types of applications against individual wireless technologies.
