Security Issues and Research of Vehicular Ad-Hoc Networks (VANET)

Kusum Mehta

Abstract


Vehicular Ad Hoc Networks is a kind of special wireless ad hoc network, which has the characteristics of high node mobility and fast topology changes. The Vehicular Networks can provide wide variety of services, range from safety-related warning systems to improved navigation mechanisms as well as information and entertainment applications.The security of Vehicular Ad Hoc Networks (VANET) has mostly directed the attention of today research efforts, while comprehensive solutions to protect the network from adversary and attacks still need to be improved, trying to reach a satisfactory level, for the driver and manufacturer to achieve safety of life and infotainment. The need for a robust VANET networks is strongly dependent on their security and privacy features, which will discussed in this paper. VANET facing many challenges that been addressed in this research, we also discuss a set of solutions presented for these challenges and problems; and we made critics for these solutions and proposed suitable solutions for some of these problems.
