Comparative Study of VANET and MANET Routing Protocols

A Vehicular Ad-hoc Network (VANET) is a type of Mobile Ad-hoc Network (MANET) that is used to provide communications between nearby vehicles, and between vehicles and fixed infrastructure on the roadside. Though VANET is a type of MANET but the routing protocols of MANET are not feasible with VANET and if they are even feasible then they are not able to provide the optimum throughput required for a fast changing vehicular ad-hoc network. The difference between VANET and MANET is that in VANET, the nodes are moving on predefined roads, and their trails aren’t too complicated and this is where the routing protocols have to be modified or changed. The differences in the architecture and characteristics have been studied in this paper to suggest the best out of the existing routing protocols. This paper presents the various protocols optimized for both the MANET and VANET. A protocol is analyzed from the existing reactive protocols which will be efficient for both the MANET and VANET.
