PERFORMANCE ANALYSIS OF AODV, DSDV AND DSR IN MANETS

Mobile Ad hoc Networks (MANETs) are considered as a new paradigm of infrastructure-less mobilewireless communication systems. MANETs are being widely studied and it is the technology that isattracting a large variety of applications. Routing in MANETs is considered a challenging task due to theunpredictable changes in the network topology, resulting from the random and frequent movement of thenodes and due to the absence of any centralized control [1][2]. In this paper, we evaluate theperformance of reactive routing protocols, Ad hoc On demand Distance Vector (AODV) and DynamicSource Routing (DSR) and proactive routing protocol Destination Sequenced Distance Vector (DSDV).The major goal of this study is to analyze the performance of well known MANETs routing protocol inhigh mobility case under low, medium and high density scenario. Unlike military applications, most ofthe other applications of MANETs require moderate to high mobility. Hence it becomes important tostudy the impact of high mobility on the performance of these routing protocols. The performance isanalyzed with respect to Average End-to-End Delay, Normalized Routing Load (NRL), Packet DeliveryFraction (PDF) and Throughput. Simulation results verify that AODV gives better performance ascompared to DSR and DSDV.
