Trust Based Location Finding Mechanism in VANET Using DST

In the near future, Vehicular Ad-Hoc Networks(VANET) will help to improve traffic safety and efficiency. Unfortunately, a VANET faced a set of challenges in security, privacy and detection of misbehaving vehicles. In addition to, there is a need to recognize false messages from received messages in VANETs during moving on the road. In this work, the application of Dempster-Shafer theorem (DST) for computing trust in the VANET environment for location finding is presented. Trust based location finding in VANETs is necessary to deter broadcast of selfish or malicious messages and also enable other vehicles to filter out such messages. Result shows that the proposed scheme is viable for VANE environment.
