Faith in Vehicles: A Set of Evaluation Criteria for Trust Management in Vehicular Ad-Hoc Network

This paper concerns about the various implemented work has been studied and analyzed to form a new survey on trust model to VANET. In this paper it is observed that there are lot of new techniques are possible to form a new trust model in VANET to provide better security with trust concern over the entire environment of trust management in VANET. This work concerns of entire trust calculation work which has been done yet over it. Here summarizing the various trust models, various security requirements, issues over it.

In recent years, Vehicular Ad Hoc Network (VANET) has developed significantly. Coordination between vehicles can enhance driving safety and improve traffic efficiency. Due to the high dynamic characteristic of VANET, security has become one of the challenging problems. Trust of the message is a key element of security in VANET. This paper proposes a Manhattan Distance Based Trust Management model (MDBTM) in VANET environment which solves the problem in existing trust management research that considers the distance between the sending vehicle and event location. In this model, the Manhattan distance and the number of building obstacles are calculated by considering the movement relationship between the sending vehicle and event location. The Dijkstra algorithm is used to predict the path with the maximum probability, when the vehicle is driving toward the event location. The message scores are then calculated based on the Manhattan distance and the number of building obstacles. Finally, the scores are fused to determine whether to trust the message. The experimental results show that the proposed method has better performance than similar methods in terms of correct decision probability under different proportions of malicious vehicles, different numbers of vehicles, and different reference ranges.

Road Side Units

A vehicular ad hoc network (VANET) is a self-organized network that can be formed by connecting vehicles equipped with on-board units. Two types of communications are provided in VANET: vehicular-to-vehicular and vehicular-to-infrastructure. In the first communication type, vehicles communicate directly, whereas in V2I, vehicles communicate through routers called road side units (RSU). Trusted authorities control the network. VANET can be used in several cases. However, the main applications of VANET are oriented to safety issues. In such context, a security problem can have disastrous consequences. In fact, an attacker can be tempted to forward false information in order to obtain some privileges such as road liberation, etc. Hence, evaluating the reliability of transmissions is vital. Trust can be used to promote such healthy collaboration. In fact, trust enables collaborating vehicles to counter their uncertainty and suspicion by establishing trustworthy relationships. The main contribution of this chapter is then the proposition of a trust-based security scheme for VANET.
