A Simulation Based Performance Evaluation of AODV, R-AODV and PHR-AODV Routing Protocols for Mobile Ad Hoc Networks

Abstract

Mobile Ad hoc Networks (MANETs) are characterized by open structure, lack of standard infrastructure and un-accessibility to the trusted servers. The performance of various MANET routing protocols is significantly affected due to frequently changing network topology, confined network resources and security of data packets. In this paper, a simulation based performance comparison of one of the most commonly used on-demand application oriented routing protocols, AODV (Ad hoc on-demand Distance Vector) and its optimized versions R-AODV (Reverse AODV) and PHR-AODV (Path hopping based Reverse AODV) has been presented. Basically the paper evaluates these protocols based on a wide set of performance metrics by varying both the number of nodes and the nodes maximum speed. A NS-2 based simulation study shows that, as compared to AODV and PHR-AODV, R-AODV enhances the packet delivery fraction by 15-20% and reduces the latency approximately by 50%. R-AODV requires lesser node energy for data transmission.

Performance Comparison and Evaluation of Different Multipath Routing Protocols Based on Various Scenario and Traffic Patterns for Mobile AD Hoc Networks

“…AOMDV [3,4,5,6,7] is the extension of AODV [8] so as to eliminate the occurrence of frequent link failures and route breaks in highly dynamic ad hoc networks. It adds some extra fields in routing tables and control packets, and follows the two rules during a route discovery phase in order to compute loop-free and linkdisjoint multiple routes between source and destination.…”

Performance Analysis Of Dsdv And Dsr Under Variable Node Speed In Hybrid Scenario

“…Das et al [15] made performance comparison of routing protocols for MANET based on the number of conversations per mobile node for a given traffic and mobility model. Small networks consisting of 30 nodes and medium networks consisting of 60 nodes were used.…”

Statistical analysis of the impact of routing in MANETs based on real-time measurements

“…Due to few MANET deployments in the real world, research in this area has been mostly simulation based [1], [2], [3], [9], [10], [14]. As simulation studies assume some ideal conditions to approximate realistic behavior, sometimes it is not possible to map the simulation results onto real-time networks.…”
