A Comparative Study of AODV and DSR Routing Protocols in Mobile Ad Hoc Networks
K. V. Ramana · 2015
Mobile Ad hoc networks (MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad hoc network is not a new one, having been around in various forms for over 20 years. The goal of the routing protocol is to have an efficient route establishment between a pair of nodes. Routing protocols used in wired network cannot be used for mobile ad-hoc networks because of node mobility .Many routing protocols such as proactive, reactive and hybrid. Reactive routing protocols have been found to be user friendly and efficient when compared to other routing protocols. The main boon of routing protocols when compared with proactive and Hybrid routing protocols is the relatively unconditional low storage requirements, higher mobility and the availability of routes when needed. There are a variety of reactive routing protocols suchasAODV,DSR,LAR1,LMR,ABR,SSI,TORA,RDMAR,MSR,AOMDV,MRAODV,ARA.However there is no study done over the efficiency of any reactive routing protocols. In this study a comparison and performance evaluation of two reactive routing protocols AODV and DSR are done using NS-2 simulator to identify the protocol that is best suited for MANETS.
