MANET is Mobile Ad-hoc NETwork, which is a group of number of mobile nodes that forms ad-hoc network. Network nodes communicate with each other without the assistance of any centralized authority or management. This paper focuses on the effects of jelly fish attack on MANET's routing protocols. Here three protocols AODV, OLSR and TORA are used. Performance of the network has been evaluated in terms of data dropped (buffer overflow), data dropped (retry threshold exceeded), load, media access delay, retransmission attempts. Simulations were carried out by using OPNET 14.0 simulator.
