In this article I have conducted a performance study of DSDV, DSR, and AODV routing protocols in Mobile Ad-hoc Networks (MANETs). I have evaluated the effect of speed, TCP types, and maximum queue length on throughput and the effect of speed on number of packet drops.I have compared the performance of DSDV (Destination Sequenced Distance-Vector) from the Proactive family with the second type is AODV (Ad-hoc On-Demand Distance Vector) from the Reactive family. I used a detailed simulation model to demonstrate the performance characteristics of these protocols. By simulating we can argue that if delay is main criteria than DSDV can be my best choice but if reliability and throughput are main parameters for selection then AODV gives better results compared to others because its throughput and packet delivery ratio is best among others. While there are many other issues that need to be considered in analyzing the performance of ad-hoc networks, I believe that our work could provide intuition for future protocol selection and analysis in ad-hoc networks.
