Prevention of Black Hole Attack in MANET: A Review

Abstract: This paper has dealt with the studying MANET (Mobile ad hoc network) with its issues, characteristics and routing with the examination of black hole attack that result in dropping of messages. The black hole attack might take place because of the malicious nodes that are consciously misbehaving and has smashed node interface. In this paper, an overview of MANET has been presented with its issues, routing protocols with its characteristics. The concept of security attacks has been shown following black hole attack. A glance of existing techniques is being given of various approaches of Black hole attack proposed by researchers in their research with the techniques used for the mitigation of black hole attack. Keywords: MANET, Black hole attack, malicious nodes, routing protocols
