学术界和工业界已经发表了关于车辆自组织网络（VANET）安全性和非安全性应用的各种正在进行的研究成果。在VANET中仍然缺乏重要研究贡献的一个主要领域是设计可靠的介质访问控制（MAC）协议。现有的关于VANET中MAC协议的调查大多讨论了通用的MAC方法，包括基于争用的MAC协议和无争用的MAC协议。为了提高VANET的网络性能，提出了一种同时采用基于争用和无争用MAC的混合MAC协议，值得进一步探索。因此，本文对VANET的混合MAC协议进行了综述。在对现有混合MAC协议进行分类的基础上，讨论了它们的优点和局限性，为车载网络高性能MAC协议的最新进展提供了一些见解。最后，提出了一些有待进一步研究的开放性问题。
Various ongoing research efforts in Vehicular Ad hoc Network (VANET) related to safety and non-safety applications have been published in academia and industry. One of the main areas in VANET that is still lacking of significant research contributions is toward designing reliable Medium Access Control (MAC) protocols. Existing surveys on MAC protocols in VANET mostly discuss general MAC methods, that include contention-based and contention-free MAC protocols. A hybrid MAC protocol that adopts both contention-based and contention-free MAC, proposed to enhance the network performance in VANET, is fruitful to be explored further. Hence, a survey of hybrid MAC protocols for VANET is presented in this paper. The benefits and limitations of the existing hybrid MAC protocols are discussed based on their classification to provide some insights into the recent advancement of high-performance MAC protocols for vehicular networks. Finally, some open research issues are highlighted as part of future research directions that need further investigations.
