A Comparative Study between AODV and DSDV Routing Protocols in Mobile Ad Hoc Networks using Network Simulator NS2

Mobile Ad hoc Networks (MANET’s) have become increasingly popular in infrastructure-less mobile wireless communication system. Nodes of these kinds of networks function as a router which discovers and maintains the route to the other nodes in the networks. Route discovery and packet forwarding operations need an efficient routing protocol. Ad-Hoc on Demand Distance Vector Routing Protocol (AODV) and Destination Sequenced Distance Vector Routing protocol (DSDV) are counted as widely used routing protocols in MANET. To this end, in this paper we compare and evaluate the functionality of AODV and DSDV routing protocols. Simulation is conducted in NS2.34 and performance evaluation is based on parameters such as packet delivery ratio (PDR), Throughput and end-to-end delay using network simulator on Linux Fedora. Simulation results show that AODV protocol is always superior in terms of packet delivery ratio, average delay and throughput as compared to DSDV protocol when number of node and scenario are changed.
