A Framework for Disseminating Trusted Safety Message in V2V Communication

VANET (Vehicular Ad hoc Networks) has become recently one of the most interesting areas of researches in the world of wireless networks. This paper reviews important aspects in VANET as well as commonly encountered problems. Our goal is to present a model to disseminate a warning message properly between vehicles and make trust decision to ensure message integrity before rebroadcast it farther. Our model enhances Vehicle to vehicle communications by avoiding three of the VANET's problems, the broadcast storm problem, the hidden node problem, and incoming message collision at the recipient nodes. A comparison had been made with the efficient directional broadcast (EDB) protocol for message disseminating to evaluate our model results.
