Now a days, Mobile Ad Hoc network is the most trendy topic for researchers. Mobile Ad Hoc network is infrastructure less wireless network that is made up of different mobile devices that creates link with other nodes on the fly and also changes their links between nodes more frequently. This type of network is more useful when one wants to get connected with some nodes for a particular session and does not wants to create a dedicated link for all the time. This paper entitles the brief discussion about MANET, various Routing protocols used to route data between these nodes. The purpose of this study is to provide the brief knowledge about MANET network. Moreover, this study entitles some of the simulation tools used in analyzing the performance of the Mobile Ad Hoc Network
