A New Trust based Routing Protocol for VANETs

Vehicular communications are expected to share different kinds of information between vehicles. However, the presence of dishonest vehicles in the route may lead to the drop or modification of the content of the exchanged messages. Thus, it is a challenge to find and maintain an efficient route for transmitting reliable information.In this paper, we propose a new routing protocol for Vehicular Ad-hoc NETworks (VANETs) based on trust. This protocol uses the trustworthiness of the path and the number of hops in order to find the optimal route.
