Mobile devices are the fundamental requirement of communication network where user wants to freely move without breaking the signal. The Mobile devices today are capable enough to communicate independently. A Mobile Ad Hoc Network (MANET) is a group of wireless mobile nodes which can communicate without any pre-existing infrastructure by creating dynamic network. This paper discuss Mobile Ad-Hoc Network (MANET) environment with the varying number of nodes. The research presents the three reactive routing protocols i.e. Dynamic Source Routing (DSR), Destination Sequence Distance Vector and Ad hoc On Demand Distance Vector (AODV) with their results to the MANET in terms of packet delivery ratio, delay, routing load and throughput. Simulation is carried out by NS2 (Network Simulation). The experiment results reflect that AODV performance it better than DSR DSDV.

The wireless network increases the mobility of devices day by day. In this case energetic devices perform an important role. Mobile Ad-hoc network is the network which is moves dynamically and creates its own visibility. The AODV is the protocol of Mobile ad-hoc network in which it is work as reactive routing protocol. The implementation of this protocol, we have done by the NS2 simulation software. NS2 is the tool to designed dynamic network. This paper discussed about AODV protocol and its related aspects such as link break due to mobility, end-to-end delay, throughput and role of inter mediator between sender and receiver.
