A Comprehensive Study on Vehicular Ad Hoc Networks: Architecture, Security and Privacy Challenges, and Future Trends

Abstract

The vehicular ad hoc network (VANET) is an interesting research area in the domain of mobile ad hoc networks (MANET). The VANET is a subform of MANET which composed of several vehicles, wireless gadgets, and roadside base stations. Through a wireless strategy, they interact with each other to create a smart and secure transport system. Due to high mobility, dynamic topology, and no power constraints, VANET is much attracted to both researcher and business persons. Regardless of its facilities and advantages, it suffers from many security and privacy issues which needed more focused on. In this paper, we have discussed security and privacy aspect of VANET. In this paper, VANET architecture, VANET models, security and privacy requirements, application of VANET, and other aspects are investigated. Additionally, we also provide some open issues and future trends, which still create a barrier for the wide adoption of VANET. The given security and privacy challenges and solutions will provide directions to researchers for designing a more secure and reliable VANET system.
