V. Lakshmi Praba, A. Ranichitra . Detecting Malicious Vehicles and Regulating Traffic in VANET using RAODV Protocol. International Journal of Computer Applications. 84, 1 ( December 2013), 36-41. DOI=10.5120/14544-2626
Recent developments in wireless communication technologies led to the evolution of Vehicular Ad-hoc Network (VANET). The main goal of VANET is to provide communication between vehicles without compromising security. Controlling the traffic and identifying misbehaving (malicious) vehicles plays an important role in road safety. A vehicle can be defined as malicious if it doesn't send acknowledgement to a trusted authority or if the speed of the vehicle suddenly changes or if its registration renewal time expires. Such malicious vehicles have to be isolated and should not be allowed to participate in the network further. In this paper, traffic control is achieved by maintaining the distance between the vehicles and the defined malicious vehicles are isolated and further communication is stopped with the malicious vehicle. The existing Ad-hoc On Demand Distance Vector (AODV) protocol has been suitably modified to achieve the above mentioned road safety measures and has been made as Robust AODV protocol (RAODV). RAODV was analyzed using the performance metrics Packet delivery ratio, Dropped packets, average End_to_End delay and Routing Overhead to show that it achieves the goals presented above.
