An Approach for Security Measures of Black Hole Attack in MANET

Abstract

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.
