Priyanka Sharma, H. P. Sinha, Abhay Bindal . Detection and Prevention against Wormhole Attack in AODV for Mobile Ad-Hoc Networks. International Journal of Computer Applications. 95, 13 ( June 2014), 34-38. DOI=10.5120/16657-6637
Security is one of the major issues in Mobile Ad-hoc Network (MANET) because of its inherent liabilities. Its infrastructure-less network with dynamic topology pose a number of challenges to security design and makes it vulnerable for different types of security attacks. In wormhole attack a pair of colluding nodes makes a tunnel using a high speed network. These colluding nodes create an illusion that the two remote nodes of a MANET are directly connected through nodes that appear to be neighbours, but are actually distant from one another. In this, a secret key is used for encryption and decryption of hello packets. Because of this, the only authentic node will remain in the network, non-authentic nodes (wormhole node) will be discarded. As a result, communication can take place only between the trusted nodes. So malicious node cannot enter into system and communication is secured.
