Neelam Khemariya, Ajay Khuntetha . An Efficient Algorithm for Detection of Blackhole Attack in AODV based MANETs. International Journal of Computer Applications. 66, 18 ( March 2013), 18-24. DOI=10.5120/11183-6302
Mobile Ad hoc Networks (MANET) are the extension of the wireless networks. They plays significant role in real life applications such as military applications, home applications etc. these networks are threatened by a lot of security attacks such as Modification, Denial of service attack, Fabrication attack etc. Black hole attack (also called Selfish node attack) is a dangerous active attack on the mobile Ad hoc Networks (MANET). In this research paper an efficient approach for the detection and removal of the Black hole attack in the Mobile Ad Hoc Networks (MANET) is described. The algorithm is implemented on AODV (Ad hoc on demand Distance Vector) Routing protocol. The algorithm can detects both the single Black hole attack and the Cooperative Black hole attack. The beauty of the algorithm described in this paper is that it not only detects the black hole nodes in case when the node is not idle but it can also detect the Black hole nodes in case when a node is idle as well.
