An Approach for Security Measures of Black Hole Attack in MANET

Mobile Ad Hoc Network (MANET) is a major next generation wireless technology which is mostly used in
future. MANET is a collection of communication devices or nodes that wish to communicate without any
fixed infrastructure and predefine organization of available links. In a MANET mobile node will be
increases and moveable, so that attacker will be attack by a malicious node which brings great challenges
to the security of Mobile Ad Hoc network. The Black hole attack is one of such security issue in MANET.
Our focus is specifically is on ensuring the security against the Black hole attack with the help of the
popular routing protocol which is mostly used in MANET. Mobile Ad hoc Networks (MANET) are the
extension of the wireless networks. They plays important role in real life applications such as military
applications, home applications etc. these networks are exposed by a lot of security attacks such as
alteration, Denial of service attack, Fabrication attack etc. Black hole attack is one of the dangerous
active attacks on the 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
