A Modified Grayhole Attack Detection Technique in Mobile Ad-hoc Networks
Mangesh M. Ghonge, P. M. Jawandhiya · International Journal of Advanced Research in Computer Science · 2010
Mobile Ad Hoc Networks are vulnerable to various types of Denial of Service (DoS) attacks for the absence of fixed network infrastructure. The Gray Hole attack is a type of DoS attacks. In this attack, an adversary silently drops some or all of the data packets sent to it for further forwarding even when no congestion occurs. Our proposed scheme comprises two steps of detecting malicious node in the network: Detection of malicious activity, Identification of malicious node. The first step is to detect any malicious activity took place in network or not and second if malicious activity took place in the network then identification of that malicious node.
