The primary objective of this research work is to study and review the behavior of AODV, TORA and DSDV routing protocols of MANET. In this paper, we will first discuss the various MANET routing protocols and then simulate the environment used for analyzing, evaluating and implementing AODV, DSDV and TORA routing protocols in MANET. Performance of above said protocols will be analyzed based on Packet Delivery Ratio, Average End-to-End Delay and Throughput. We will studythe effect of change in number of nodes on MANET routing protocols. Here, we will analyze and compare the performance of MANET routing protocols based on both CBR and TCP based traffic patterns. We have used the NS-2 simulator for performing various simulations and used awk scripts and java for analyzing the results.
