Measuring the Impact of JellyFish Attack on the Performance of Mobile Ad Hoc Networks Using AODV Protocol

"MANETs are susceptible to various attacks. Out of which Denial of Service (DoS) are most dangerous and very difficult to detect and defend. Jellyfish is a new DoS attack categorized as JF reorder attack, JF periodic dropping attack and JF Delay variance attack. In JF delay variance attack, a JF attacker node intrudes into forwarding group and delays data packets for some amount of time before forwarding. Due to this attack, high end-to-end delay is introduced in the network resulting in low performance (i.e. throughput). In this paper, the effect of JF delay variance attack on MANET using AODV as a routing protocol has been calculated and the performance analysis is done with respect to some network parameters like throughput, end-to-end delay etc."
