Security Analysis of Vehicular Ad Hoc Networks

The wireless ad hoc network is the decentralized type of network and vehicular ad hoc network is the type of wireless networks. In the vehicular ad hoc network vehicles can move freely in the network with the variable speed. The security is the major issue of the network which reduces network performance. In this paper, various security issues related to vehicular ad hoc network is discussed and propose novel technique for the isolation of DDOS attack in VANETs.
