Krishna Kumar Joshi, Neelam Khemariya, Deepak Chaudhary . An Efficient Algorithm based on Fibonacci pattern Hound packets for Detection of Wormhole Attack in DSR for Mobile Ad Hoc Networks. International Journal of Computer Applications. 63, 11 ( February 2013), 23-28. DOI=10.5120/10511-5475
Wireless networks are playing very important role in the present world. Mobile Ad hoc Networks (MANET) are the extension of the wireless networks. These networks are playing crucial role in the each and every field of the human life. They are used in those places where a simple wireless network cannot use. They play a significant role in real tile applications such as military applications, home applications wireless sensor applications etc. Due to their adaptive nature they are threatened by number of attacks such as Modification, Black Hole attack, Wormhole attack etc. Wormhole attack is one of the dangerous active attacks in the mobile Ad hoc Networks (MANET). In this paper a secure and efficient approach for the detection of the wormhole attack in the Mobile Ad Hoc Networks (MANET) is described. The algorithm is implemented in a very popular on demand routing protocol, called DSR (Dynamic Source Routing) protocol. In this approach the solution is provided by sending the Hound Packet in the order of Fibonacci series and also modifies the table entries in terms of storing them in sorted order, so that the processing of Route Discovery becomes faster.
