Özet: Ad-hoc networks are formed by multiple nodes gathered as each node is dependent of at least one node in transmission range to communicate with other nodes that are out of range. Under certain conditions, some of nodes would disobey routing protocol rules with various reasons, such as, malfunction, resource hunger or may be just to block one another's communications. Modern ad-hoc routing protocols mostly suffer from routing misbehavior attacks as in widely described in literature like Black Hole or Gray Hole attacks. Because of that, recently, research on detection and prevention of routing misbehavior actions on ad-hoc networks is widely on focus of engineering community. In this paper, a novel routing misbehavior prevention system is explained after description of how misbehavior attacks mostly affect routing protocols and possible reactions. The proposed prevention system is inspired by the human interaction system like in the case one person investigates another person in which investigator tries to collect information from others who know the person under investigation. The approach is later explained in detail as to be applied to AODV routing protocol. Modifications that are needed to be applied to the original route discovery system of AODV to enable a reaction system is also described. In order to illustrate the success of the novel approach as applied to AODV routing algorithm, Black Hole attack is implemented on AODV under NS-2 network simulator software and comparative NS-2 simulation results are given.
