An Efficient and Secured Routing Protocol for VANET

Since few years, Vehicular Adhoc Networks(VANET) deserve much attention. Routing and security are the two most important concerns in this type of network. A number of routing protocols already exist for vehicular ad hoc network but none of them are made to handle routing and security issues side by side. In this paper we propose a new junction-based geographical routing protocol which is capable of dealing with routing as well as security issues. This protocol consists of two modules: (i) To implement routing, at first this protocol selects appropriate junctions dynamically, through which a packet must transmit in order to reach to its destination. (ii) To deal with security issues, we have introduced the concept of mix-zones to prevent vehicle tracking by unauthorised users. At the end, the performance of the proposed work has been compared with some well known existing routing protocols depending upon some parameters like packet delivery ratio and normalized routing load in a simulated environment.
