A Survey on Security in VANETs

摘要

Vehicular Ad-hoc network (VANET) is a very promising and upcoming technologyusedfor traffic management and for facilitating road safety along with entertainment system. Implementation of VANET requires building trust among the vehicle owners. Without developing trust, it cannot make any vehicle owners to be a part of vehicular network and without active participation of vehicle owners, V ANETs cannot be completely implemented. Therefore, providing security and maintaining the owner's privacy has become a major issue in V ANETs. To provide better security and maintain privacy, one should understand the various possible attacks on the network and the nature of their behavior. Various research papers over the years have discussed about V ANET architecture, Application areas, Challenges and security issues. Most of the papers discuss about the security services and the related work on security but a deeper understanding on each type of attacks on network will help any researcher to develop a security mechanism and the proposed solution can work optimally against one or multiple security attacks. This paper presents a comprehensive survey on various attacks and the proposed solutions by the various researchers and also analysis and comparison of results for the simulated proposed solutions.
