DSR (Dynamic Source Routing) is an on-demand routing protocol. This means routes are not pre-established routes and routes are only active during the transmission. The main problem in the MANET is attack on data. As users know in MANET they cannot differentiate which node is the attacker node and which is benign node. So, the attacker node can easily capture the data. And these types of attacks are known as black-hole, worm-hole and gray-hole attack. So, identifying which node is genuine node or for preventing the data from the attacker node is necessary in MANETs.
