Abstract
Adhoc On-demand Distance Vector (AODV) is the well-known reactive routing protocol of Mobile Adhoc Network (MANET). Absence of security mechanism in AODV disturbs the routing because of misbehavior of attack and hence, degrades MANET's performance. Secure and efficient routing is a need of various commercial and non-commercial applications of MANET including military and war, disaster and earthquake, and riot control. This paper presents a design of important network layer attacks include black-hole (BH), gray-hole (GH) and worm-hole (WH) attacks. The performance analysis of AODV protocol is carried out under the influence of each designed attack by using the network simulator, NetSim. Simulation results show that, the network layer attacks affect packet delivery ability of AODV protocol with low energy consumption and in short time. Design of attacks helps to understand attack's behavior and hence, to develop security mechanism in AODV.
