A Survey on Topology based Reactive Routing Protocols in Vanets
VANETS comes under the shadow of MANETS. It provides a prominent approach to the intelligent transport system. In this paper, we have explained the different number of topology-based reactive routing protocols for the smart transport system. Vanets provides many applications with its infrastructure less topology like traffic information, vehicle safety etc. Designing a new and efficient routing protocol for all the applications of vanets is very difficult so we have compared all the protocols with a detailed analysis so that we may find the best among them after that we may improve the routing process by considering the different types of parameters. At first, we will discuss about the basics of vanets and its characteristics later we will discuss the categories of routing protocols and their comparative analysis.
