车联网（IoV）是一个活跃的创新领域，也是通过车辆与物联网（IoT）集成实现智慧城市的重要工具。车联网是一种分布式网络，有助于处理车辆传感器和车辆到一切通信（V2X）生成的数据，从而实现自动驾驶和排队等新应用，同时提高安全性和能源效率。在物联网中，传感器和相互依赖的设备传递关键信息，以便在生态系统中有效实施实时应用。尽管取得了所有这些进步，但一个至关重要的挑战是在互联设备之间建立顺畅的通信，具体来说，就是车联网中的互操作性-这是一个看似简单的概念，但尚未完全解决，以实现完全集成的生态系统。这主要是因为家庭、电网和医疗保健等网络领域都是在孤岛中开发的，独立运行不同的流程和协议。因此，在整个生态系统中尚未实现无缝的信息交换，这阻碍了车联网最大限度地发挥其全部潜力。在本文中，我们深入分析了互操作性的现状，并全面调查了车联网中的挑战。我们提出了一个分类的互操作性的方法，审查以前的工作提出的解决方案，并提供有关如何解决当前的挑战的见解。最后，我们确定了持续存在的开放问题和未来的研究方向。
The Internet of Vehicles (IoV) is an active area for innovation and an essential tool in achieving smart cities through the integration of vehicles with the Internet of Things (IoT). IoV is a distributed network that aids in handling the data generated by vehicular sensors and vehicle-to-everything communication (V2X), thus enabling novel applications such as autonomous driving and platooning while increasing safety and energy efficiency. In IoV, the sensors and the interdependent devices relay critical information for the efficient implementation of real-time applications in the ecosystem. Despite all these advancements, a vital challenge is establishing smooth communication among interconnected devices, concretely, interoperability in the IoV—a deceptively simple notion that is not yet fully addressed to achieve a fully integrated ecosystem. This is mainly because the networked domains, such as home, grid, and health care, are developed in silos, operating independently with diverse processes and protocols. Hence, seamless exchange of information is yet to be achieved across the ecosystem, hindering the maximization of the full promise of IoV. In this paper, we provide an in-depth analysis of the present state of interoperability and comprehensively survey the challenges in IoV. We present a taxonomy of interoperability approaches, review solutions that prior work have proposed, and provide insights on how to address the current challenges. Finally, we identify open problems that persist and future directions for research.
