InMANET, routing is severely vulnerable to various kinds of routing attacks viz-a-viz:black hole attack, link with holding attack, link spoofing attack, replay attack,wormhole attack and colluding mis-relay attack. All of these attacks influence thenormal operations of MANET in different ways. With the dynamic network topologyin MANET, routing functions are carried out by available nodes since there are fixedbase stations. In such routing environment, each node acts both as a
