Trust Score Evaluation Scheme for Secure Routing in VANET

Abstract

An Intelligent Transportation System has given a new dimension for Vehicular Communication so called VANET. This Vehicular network is the subcategory of Mobile Adhoc Network. The Vehicular technology enables the communication between the transporting system and with infrastructure through a wireless medium. The purpose of communication is to share environmental related information other messages in order to alert the vehicles that are coming behind. This will make the user know the information well in prior which avoids unnecessary accidents and uncomforted situations. The messages are gathered by the vehicles which on in front will pass that to other transports or infrastructure. The message dissemination happens between the transports and the infrastructure which are connected in the network. For this, it is necessary to check the genuineness of the transport, where there can be a possibility for disseminating bogus messages for their own benefits. These vehicles are believed to be untrusted transport that needs to be identified and has to be eliminated from the network topology to guarantee a secure network. In this proposed work, a trust evaluation scheme for effective trust calculation in identifying the bogus transport. The primary focus of this proposed method is to detect anonymous transport and find the optimal path for the message to reach the destination. The parameters that are mainly considered are Packet Delivery Ratio, Delay. This proposed scheme achieves better accuracy compared to the existing system.
