Mobile Ad hoc NETworks (MANET) is a wireless network where nodes work in standalone fashion. The MANET faces various security challenges due to the environment in which it is deployed. The nodes of mobile Ad hoc networks are thus susceptible to compromise. The networks are particularly vulnerable to Denial Of Service (DOS) attacks launched through compromised nodes or intruders. One of the major attacks on MANET is Denial Of Service (DOS) attack, which is caused by intruders or malicious nodes. The Flooding attack is one of the DOS attack against on demand routing protocols. In this attack a malicious attack broadcast bulk Route REQuest (RREQ) so that all links get overloaded and all bandwidth is consumed.
