Deepak Journal on Mobile Applications and Technologies 2394-0239 2 2 37 42 MANETs, Wormhole Attack, Wormhole Attack Classification, DYMO, FSR Mobile Ad-hoc Network (MANET) consists of a collection of wireless mobile nodes that are capable of communicating with each other. MANETs are infrastructure-less, lack of centralized monitoring and dynamic changing network topology. So, this network is highly vulnerable to attacks due to the open medium. Wormhole attack is difficult to detect because they do not create any separate packets. In this paper, performance of wormhole attack is analyzed using DYMO and FSR routing protocol. The result analysis shows the impact of wormhole attack on MANETs in terms of throughput, average end-to-end delay, average jitter and packet delivery ratio.
