A Novel Scheme for Prevention and Detection of Black Hole & Gray Hole Attack in VANET Network

Abstract

: VANET is an application used for the intelligent transportation system which improves traffic safety as well as its efficiency. We have reviewed the patents related to vehicular Ad-Hoc Network and their issue. To avoid road accidents a lot of information we need in advance. This paper has developed a framework which minimizes the possibilities of the black hole attack in VANET. According to us, there are two possible solutions for this purpose. The first is to see alternative routes for the same destination. The second compromises of exploiting the packet header's packet sequence number which is always included in each packet header. The second procedure is able to verify that 72% to 96% of route which is discovered depends on pause time t which is the minimum time for delay in the packet transition in the network when AODV routing protocol is used for packet transitions. The framework is analyzed for the possible attacks by the Black Hole, and Gray Hole attacks and also effects of the attacks are recorded and studied by practically using it. A secured VANET is essential for the future of the network. Currently acquiring this network will boost the possibility of VANET to develop and reduce the time of its implementation in the real world scenarios. In this work it is concluded that both attacks can be implemented and detected over the network apart from of the fact that both attacks are categories differently.

Detection and Mitigation of Smart Blackhole and Gray Hole Attacks in VANET Using Dynamic Time Warping

“…Kumar et al [14] introduced a multi-solution approach to remove the effects of black/ gray hole attacks in VANET. The behavior of attacker nodes was analyzed at various time intervals.…”
