Vehicle to Everything (V2X) communication capability has drawn the attention of various government agencies, industries, and research communities to implement the Vehicular Ad hoc Networks (VANETs) in real-time. Excellent results have been yielded for the ephemeral nature of communicating cars in the VANET domain, aiming to provide safety in emergencies. Though some crucial factors might be overlooked in some literature, this study provides a systematic analysis for selecting the relevant criteria for clustering in VANETs. Moreover, this survey contributes to effectively validate new designs and promote VANET technology towards deployment. With the above aim, to keep the newcomers and researchers abreast of the latest communication technologies in VANETs, the relevant directions for future work in this space are suggested.

车用万物（V2X）的通信功能已吸引了各个政府机构，行业和研究社区的关注，以实时实现车载自组织网络（VANET）。在VANET领域，通讯车辆的短暂性已经取得了出色的结果，旨在在紧急情况下提供安全性。尽管一些文献中可能忽略了一些关键因素，但本研究为选择VANET中的聚类相关标准提供了系统的分析。此外，该调查有助于有效地验证新设计并促进VANET技术的部署。出于上述目的，为了使新手和研究人员了解VANET中的最新通信技术，建议了该领域未来工作的相关方向。
