# Information-Centric Network-Based Vehicular Communications: Overview and Research Opportunities
## 7 Conclusions  
In this paper, we addressed a promising paradigm, Vehicular Ad hoc Network (VANET), based on Information-Centric Network (ICN), with its potential deployment in three other emerging models, i.e., Software Defined Network (SDN), Cloud, and Edge computing. We explored the applications of VANET in the mentioned three architectures corresponding to ICN that face numerous problems in the IP-based Internet model. VANET-based ICN influences contents in the stated models in a perfect way among VANET nodes (e.g., RSUs and vehicles). We presented the ICN-based VANET concept along with its challenges in terms of security, mobility, routing, naming, caching, 5G communications. However, the practicality of ICN-based VANET with SDN, Cloud, and Edge imposes more elaboration and requires detailed analysis as these models are not fully developed.
