Security of Vehicular Ad-Hoc Networks (VANET): A survey

Abstract

Abstract In the previous couple of years, various types of researchers concentrate on Vehicular Ad-hoc networks (VANET) field due to various facilities it provides. VANET a subgroup of mobile ad-hoc network (MANET), refers to a group of intelligent nodes i.e. (vehicles) on the road. These intelligent vehicles interact with one other or with the road side unit (RSU) for providing safer roads and a more efficient driving experience and providing security against attackers. In VANET messages are conveyed in an open wireless channels Security is therefore the most concerning issue in VANET. In this paper several types of the security issues, requirements, attacks, attackers in VANET have been described and some recent solutions to solve the security problems with their advantages and disadvantages have been discussed.
