Abstract

MANET and VANET are the active research areas and lots of routing protocols have been proposed for use in these areas.. In MANET, nodes are connected through wireless channels in a network and each node acts as a router and as a host. One of the scenario of MANET is Vehicular ad-hoc networks. For communication in VANET, efficient Routing Protocols are needed. Because of highly changing network topology and frequent disconnection it\'s strenuous to design an efficient routing protocol for vehicles, there can be two types of VANET that are V2V(Vehicle to Vehicle) and V2RSU(Vehicle to Road Side Unit). Because of daily happening of accidents VANET is one of the affecting areas for the refinement of Intelligent Transportation System (ITS) which can insure passengers and road safety. The Intelligent Transport Systems gives information if there exists any emergency and tells about traffic density. the traffic and traffic density. The existing routing protocols for VANET are not efficient enough to meet all traffic scenarios. Worthy routing protocols are required to initiate communication between vehicles in future for passengers and road safety. This paper shows literature survey related to Reactive and Proactive Routing Protocols of MANET as AODV, DSDV, OLSR, DSR. Analysis and characterization of these protocols is shown in the paper which helps in further improvement of existing routing protocols. Keywords: MANET, VANET, AODV, DSDV, DSR, OLSR.

Introduction

One type of the wireless Networks is the Mobile ad-hoc Networks and another type of wireless Network is Vehicular Ad-hoc Network. In MANET, nodes communicate with each other without an existing infrastructure. A mobile ad-hoc network is a set of wireless mobile nodes which forms temporary network without any stable infrastructure. In MANET, each node works as a router and as host. These nodes are peer to peer, self configuring and free to move in any direction because of this links to other nodes changes rapidly.

Conclusion

In this paper we surveyed about Reactive and Proactive Routing protocols of MANET. We did the comparative analysis between the mobile ad-hoc network and the vehicular ad-hoc network. Our literature survey focuses on protocols like AODV, DSR, DSDV and OLSR. the Reactive protocols will be the best if we want to use any existing protocol with the same set of rules in both the VANET and MANET. based on previous research work and study AODV results better than any other reactive protocols for both MANET and VANET.
