Detection and Mitigation of Misbehaving Vehicles from VANET

Abstract

VANET means vehicular ad hoc network is nothing but the group of independent vehicles nodes which are moving throughout the wireless network freely. Such kind of networks are temporary as the vehicles and their positions are not fixed and hence the all the routing paths which are established in order to make the communication in between the source and destination are on demand and depends on the nodes movement into the network. The architecture is not at all needed for such kind of networks. Role of routing protocols is most important for the VANET which is used to route the data from source to destination, but they are also vulnerable to the many of the security attacks in the VANET. Due to the unprotected nature of the VANET networks routing protocols, such networks also unprotected from the malicious vehicles in the network itself. This paper presents new approach for not only the detection of malicious vehicles attack but also their prevention from the VANET. Proposed algorithm is referred as Detection and Prevention of Malicious Vehicles (D&PMV). The malicious vehicles detected using the monitoring process over the VANET, once they are detected, proposed algorithm is applied for the prevention of the same. The detection of malicious vehicles is based on DMV algorithm presented earlier.
