A Mobile Ad hoc network (manet) has emerged as an autonomous, multi-hop, wireless and temporary type of network which works within the constraints like bandwidth, power and energy. Manet can be observed as an open type of network where nodes become a part of any network at any time that’s why it is susceptible to different types of attacks. Wormhole attack is most threatening security attack in ad hoc network where an attacker node receives packet at one location and replay them at other location which is remotely located far. In this paper, we study and compare the performance of AODV, DSR and ZRP under the impact of multiple wormhole attacker nodes. Diverse scenarios are characterized as like average of 50 runs and mobility. By statistical placement of multiple wormhole nodes across the network, we evaluate the performance in terms of throughput, packet delivery ratio, packet loss, average end to end delay and jitter. Finally based on the simulation we investigated the most affected routing protocol in terms of network metrics.
