MANET is one of self configuring fastest emerging wireless technology. MANET is multi-hop wireless network of autonomous mobile nodes with no preset infrastructure where each node can move in any direction as well play a role of router. Dynamic nature of this network makes routing protocols to play a prominent role in setting up efficient route among pair of nodes. Therefore many proactive, reactive & hybrid routing protocols have been proposed, among which one of well known is AODV due to its high performance gain. Cooperative nature of nodes exposes MANET to various kinds of passive & active attacks. Sinkhole is one of severe kind of attack which attempts to attract most of network traffic towards it & degrade the performance of network. this paper, shows performance metrics as throughput, PDR, End to end delay & Packet loss. Simulation is carried out using widely used simulator NS2.
