Abstract

Vehicular Ad-hoc Network (VANET) is becoming a potential solution to improve traffic safety and efficiency by facilitating communication among vehicles via exchanging reliable messages. Therefore, reliable and authentic message delivery from legitimate vehicles is a prerequisite. But internal malicious vehicles may disrupt proper functioning by discarding or fabricating packets. For this objective, a computationally efficient direct trust-based model is proposed which evaluate vehicle behavior by verifying the correctness of communicated message even in sparse network situation. We ensure the reliability of each communicated message by secure path selection in Direct-trust-based GPSR routing protocol (DT-GPSR) incorporating trustworthy vehicle. Simulation and analyses show our model help legitimate vehicles to mitigate effect of malicious vehicle communicating false or bogus data to disrupt network.
