Abstract
Vehicular ad hoc networks (VANETs) are becoming promising and popular technologies in the recent intelligent transportation world. They are used to provide an Intelligent Transportation System (ITS), efficient Traffic Information System (TIS), and Life Safety. The mobility of the vehicles and the volatile nature of the connections in the network have made VANET vulnerable to many security threats. Black hole attack is one of the security threat in which node presents itself in such a way to the other vehicles that it has the freshest and the shortest path to the destination. Hence in this research paper an efficient approach for the detection and prevention of the Black hole attack in the Vehicular Ad Hoc Networks (VANET) is presented. The proposed solution is implemented on AODV (Ad hoc On demand Distance Vector) routing protocol one of the most popular routing protocol for VANET. The proposed strategy can detect both the single and the Cooperative Black hole attacks in the early phase of route discovery. The simulation is carried on NS-2 and the results of the proposed scheme are compared to the fundamental DYMO routing protocol, this results are examined on various network performance metrics such as packet delivery ratio, throughput and end-to-end delay. The found results show the efficiency of the proposed method as the delivery ratio and end to end delay of the network does not deteriorate under a black hole attack.
Highlights
Because the high number of road accidents and with the improvement in the wireless communication technologies and, vehicular ad hoc network (VANET) are used to provide an efficient Traffic Information System (TIS)
Black hole attack is one such attack and a kind of denial of service (DoS) attacks [7] where a malicious node exploits the vulnerabilities of the route discovery process of the routing protocol to advertise itself as having the shortest and the freshest path to the destination even if no such route exists in its routing table since in Ad Hoc On-Demand Distance Vector (AODV), any intermediate node that has a fresh route could respond to Route Request (RREQ) message
This paper provides routing security to the AODV routing protocol by detecting and preventing the threat of Black Hole attacks
Summary
Because the high number of road accidents and with the improvement in the wireless communication technologies and, vehicular ad hoc network (VANET) are used to provide an efficient Traffic Information System (TIS). VANET is a subclass of Mobile Ad-hoc Network (MANET) which consists of number of nodes (vehicles) communicating with each other without a fixed infrastructure [19]. Aiming to maximize Packet Delivery Ratio (PDR) and throughput while minimizing packet lose ratio and controlling overheads In this direction many routing protocol has been proposed which has important role in organizing the network safety. AODV is the most frequently used reactive routing protocol in VANET [4]. We will concentrate on well-known and Intelligent black hole attack in AODV base VANET. AODV is a reactive routing protocol as it is mentioned above; nodes will only send the control data only when is necessary. The remaining of this paper is organized as follows: In section II we introduced background of AODV routing protocol and black hole attack.
