A Mobile Ad-hoc NETwork (MANET) consists of a number of mobile wireless nodes, among which the communication is carried out without having any centralized control. MANET is a self organized, self configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The mobile nodes can receive and relay packets as a router. Routing is a critical issue and an efficient routing protocol makes the MANET reliable. For almost last 10 years, a number of routing protocols have been studied and their performance comparisons are made by many researchers. Most of the previous research on MANET routing protocols have focused on simulation study by varying various parameters, such as network size, pause times, node mobility independently etc. In this work a study has been carried out on the behavioral aspect of three different MANET routing protocols i.e. AODV (Ad Hoc On-Demand Distance Vector), DSDV (Destination Sequenced Distance-Vector) and DSR (Dynamic Source Routing Protocol) using the NS-2 simulation tool. The performance of these routing protocols is analyzed in terms of their average throughput, average delay & maximum packets in queue and their results are shown in graphical forms. The main objective of this study is to create a choice guide of routing protocol for a given network scenario, based on the relative performance of the protocols under various scenarios.
