Abstract:

A Vehicular Ad hoc Network (VANET) is a selforganizing network, which is specifically designed for communications between vehicles without controlling center. So drivers can get vehicular status and realtime traffic information without the scope of sight. Since the features of VANETs are selforganizing and nocenters, the original mature security control technology based on centralized solution is no longer suitable. A novel trusted routing protocol in VANETs was proposed by introducing the concept of experienced trustiness, which is incorporated into trust metrics. The reputation of last hop is incorporated into the factors of experienced trustiness. The theory of experienced trustiness was used to study nodes' behavior. A new forwarding rule was designed according as the concept of experienced trustiness to encourage packets forwarding and discipline selfish behavior in VANETs. Also some recommendatory methods to calculate the experienced trustiness were given.
