A Noble Reactive Routing Protocol for Mobile Ad Hoc Network based on AODV

A Mobile Ad hoc Network (MANET) is a kind of wireless ad-hoc network. The infrastructure less and the dynamic nature of Mobile AD-HOC networks demands new set of networking scheme to be executed in order to provide efficient end-to-end communication. Mobile AD-HOC network is a collection of mobile nodes which are arbitrarily and dynamically located. Due to high mobility of nodes the topology of ad-hoc networks become highly dynamic. Efiicient routing protocol can make MANET more reliable. MANET is expected to be very useful for the formation of temporary networks in battlefield and disaster recovery such as fire, safety and rescue operations, meetings in which people likes to quickly share information. The main challenging issue of MANET is that of discovering the routes between the mobile nodes due to the continuously changing topology of ad hoc networks. In this paper we have studied the Ad Hoc On-Demand Distance Vector (AODV) routing protocol which is a reactive routing protocol. In this paper, we provide an overview of recent years enhancements that have been suggested to improve the working of AODV like RAODV, MAODV, etc.
