Effects Of Wormhole Attack On AODV And DSR Routing Protocol Through The Using NS2 Simulator

Mobile Adhoc Networks (MANET) are self organizing, decentralized networks and possess dynamic topology, which make them attractive for routing attacks. Attacks on ad hoc networks can be classified as passive and active attacks, depending on whether the normal operation of the network is disrupted or not. The security of the AODV and DSR protocol is compromised by a particular type of attack called 'Worm hole attack'. Wormhole attack is a network layer attack observed in MANET, which completely disrupts the communication channel. In This paper we analyses the performance of AODV and DSR routing protocols with and without wormhole attack using Network Simulator 2. For analyzing the performance we considered total packets received, total bytes received, first packet received, last packet received, average end-to-end delay and throughput as measures.
