车辆和智能交通基础设施之间无处不在的连接将促进必要的信息流，以增强智能服务，实现高效、安全和环保的人员和货物运输。尽管车载通信技术正在迅速向无处不在的联网汽车发展，但针对这类汽车的网络协议设计仍处于初级阶段，面临着多重令人生畏的挑战。在这篇文章中，我们倡导使用以信息为中心的网络(ICN)范式来充分实现互联汽车，即集成车载计算系统和汽车到数字世界。我们讨论了为互联汽车设计基于ICN的协议所面临的新挑战，并正式讨论了当前的辩论，即这种协议的设计应该采用哪种传输模式(广播或单播)。关于这场辩论，我们建议对广播和面向单播的解决方案中最新的和有代表性的协议进行分类，并强调每种方法的权衡。基于一项关键的定性评估，我们主张自适应和混合方法对于以信息为中心的联网汽车将表现得更好。因此，我们为进一步设计基于ICN的互联汽车协议提供了指导。最后，我们讨论了未来可能考虑的一些研究方向，以推进互联汽车的内容分发过程。
The ubiquitous connectivity between vehicles and smart transportation infrastructure will facilitate the information flow necessary for empowering smart service for efficient, safe, and eco-friendly transportation of people and goods. Although vehicular communication technologies is quickly advancing toward ubiquitously connected cars, the design of networking protocols for such vehicles is still in its infancy, facing multiple daunting challenges. In this article, we advocate for the use of the information-centric networking (ICN) paradigm for the full realization of connected cars, that is, the integration of both in-car computing systems and the car-to-digital world. We discuss the emerging challenges for the design of ICN-based protocols for connected cars, and we formally put the current debate into perspective regarding which transmission mode (broadcast or unicast) should prevail for the design of such protocols. Concerning this debate, we propose to classify recent and representative protocols in broadcast and unicast-oriented solutions, and we highlight the trade-offs of each approach. Based on a critical qualitative evaluation, we advocate that adaptive and hybrid approaches would perform better for information-centric connected cars. Hence, we provide a guideline for the further design of ICN-based protocols for connected cars. Finally, we discuss some future research directions that might be considered to advance the process of content distribution in connected cars.
