Trust-BZB: Towards a trust-driven routing in vehicular networks

Vehicular networks are the building blocks of the intelligent transportation systems (ITS). Several applications are built to provide more safety and efficiency to users of the roads. Particularly, safety applications are the most critical and vital. This kind of application is very challenging as it is highly demanding in terms of reliability and latency. On the other hand, safety-related data should be delivered intact and in a secure manner. Vehicular technologies should therefore provide these requirements for an effective operation of these applications. In this paper, we propose an efficient receiver-based routing protocol that considers on the one hand the dynamicity and the characteristics of the vehicular environment and on the other hand the trustworthiness of the potential relays of safety data in order to secure the dissemination process. Simulations results showed that our trust-BZB reduces the delay of delivery of the information in a non-secure environment.
