Priority based emergency message forwarding scheme for time critical models in VANET

In the era computing, there is huge research is going in VANET since last few years. VANET is ad-hoc communication network which is formed by connecting vehicles. The navigation system needs to be more intelligent at the same time security should not be compromised. The comprehensive literature survey shows there is a need for intelligent and secure navigation system. There are lots issues need to address. This paper proposes a navigation system that efficiently works in real time scenario. In the proposed architecture some security aspects also considered like authentication, confidentiality and privacy of vehicle and driver. The performance of proposed system evaluated against QoS parameter. In proposed system find shortest path of vehicle depend on real road condition, therefore it display shortest path by skipping accidental road. It also provides priority to broadcast message.
