The rapid proliferation of wireless networks, deployment of many mobile computing devices and applications has changed the shape of network security.One such field which needs more security in comparison to wired networks is the mobile ad hoc network (MANET).The term "ad hoc" means self-organized nodes without any centralized infrastructure.In Jellyfish packet dropping attack, the attacking node attracts more data traffic by advertising themselves having the best path to other destinations in the network.Further, these jellyfish nodes selectively drop data packets degrading network throughput.This paper mainly focuses on jellyfish packet dropping attack, its consequences and proposes mechanism for detection & prevention of it in the context of AODV routing protocol.The simulations are carried on NS-2 simulator and performance is evaluated in terms of packet delivery ratio, throughput and routing overhead.
