An ad hoc network is a collection of wireless computers with dynamically changing topology, communicating among themselves over possibly multi-hop paths, without the help of any infrastructure. Although many ad hoc network routing protocols have been proposed (AODV, SAODV, DSR etc), none of them considers or solves the security problems efficiently within the restrictions of ad hoc networks. Ad hoc networks are vulnerable to many types of attack like Denial Of Service (DOS), Byzantine Attack, Black-hole Attack, Flooding Attack, etc. In this paper, the authors put forward an efficient and reliable security mechanism based on the AODV routing protocol which protects the ad hoc networks from different types of flooding attacks.
