Abstract:
Vehicular Ad hoc Network (VANET) is a new type of Mobile Ad hoc Network (MANET) which refer
to a set of smart vehicles used on the road. Based on wireless Local Area Network (LAN) technology,
these cars deliver communication services to each other and to Road Side Infrastructure (RSU). Road
accidents and related sequences are becoming more common over the world, necessitating the
development of methods that include road safety and regulation. Even vehicles with short-range
networks can successfully use VANET to construct an intelligent transportation system (ITS). Travelers
will benefit from VANET since it will improve road safety and convenience. However, such technology
is already subject to a number of vulnerabilities, posing a slew of security issues that must be addressed
before VANET technology can be used realistically and securely. The key advantages of VANETs are
such that they improve traffic safety and vehicle protection while also safeguarding drivers' privacy from
malicious attacks. Because the information communicated is dispersed in a freely accessible
environment, safety is among the most important challenges associated to VANETs. This paper offers a
summary of security concerns and the challenges they provide. The various types of VANET
applications are discussed, as well as certain security needs, threats, and designs for addressing the
security issue.
