A MANET is an infrastructure-less type network, which consists of number of mobile nodes with wireless network interfaces. MANET is a wireless network that consists of nodes which are mobile in nature. In order to make communication among nodes, the nodes dynamically establish paths among one another. Each node in the network acts as a router which provides the flexibility to the topology of the network. There are many routing protocols in the MANET such as DSR, AODV, TORA, etc. and these are classified in different routing protocols.
