MANETs represent complex distributed systems which are comprised of free moving mobile nodes which use dynamic topology and are infrastructure less networks. This paper is to present the complete study on the performance and behavior of reactive, proactive and hybrid approach in MANETs. To evaluate the performance of these protocols different scenarios with varying nodes have been simulated using the NS-2 simulation tool. There are some performance metrics which are used to describe the performance of these given routing protocols .e.g. number of packets sent, number of packets received, number of packets dropped, normalized routing load and network overload etc.
