Performance Metric Comparison of AODV and DSR Routing Protocols in MANETS

The mobile Ad hoc network is a dynamic network in which a temporary network is formed dynamically by the mobile nodes without any centralized administration. There are a no. of existing routing protocols which are classified mainly into table-driven and on-demand routing protocols. Among all on-demand routing protocols, AODV and DSR routing protocols are the most efficient routing protocols which are designed particularly for wireless ad hoc networks comprising of mobile nodes. These protocols have quick adaptation to changes in topology, low network usage, less memory and processing issues in the ad hoc network. In this paper an effort has been made to compare the performance of AODV and DSR on the basis of varying node velocity. To measure the performance, three commonly used network performance metrics are used that are packet delivery ratio (PDR), throughput and average end-to-end delay. The simulation experiments are done using the NS-2 network simulator that is in use to run wired and wireless ad hoc simulations. The trace files are studied and analysed using awk scripts (delay.awk and throughput.awk). Oracle VM Virtual Box is used to run the network simulator.
