摘要：In multihop wireless adhoc networks, cooperation between nodes to route each other’s packets exposes these nodes to a wide range of security attacks. Also due to the vulnerability of the routing protocols, the wireless ad-hoc networks face several security risks. A particularly severe security attack that affects the adhoc network routing protocols, is known as the wormhole attack. The wormhole attack is carried out as a two phase process launched by one or more than one malicious nodes. In the first phase, these malicious nodes, called as wormhole nodes, try to lure legitimate nodes to send data via them by participating in the network. In the second phase, wormhole nodes could exploit the data & affect the communication by misbehaving. In this paper we have simulated the wormhole attack in wireless adhoc networks & Manet’s. And then we evaluated & discussed the impact on the network by comparing the results without and with wormhole attack. The Wormhole attack was simulated using different scenarios. Thus we studied the impact of the wormhole attack on the respective networks. The parameters like throughput, packet loss and end-to-end delay were calculated using different scenarios for evaluating the impact on wireless adhoc networks and Manet’s.
