Abstract

MANET (Mobile Ad-Hoc Network) has a weakness from a security aspect because it operates where no wired network is built, which causes the exposed media, dynamic topology, and the lack of both central monitoring and management. It is especially difficult to detect and mitigate a malicious node because there is not a mediator which controls the network. This kind of malicious node is closely connected to the routing in the field of study of Ad-Hoc security. Accordingly this paper proposes the method on how to enhance the security for the safe and effective routing by detecting the malicious node. We propose MBC (Identification technition of Malicious Behavior node based on Collaboration in MANET) that can effectively cope with malicious behavior though double detecting the node executing the malicious behavior by the collaboration between individual node and the neighbor, and also managing the individual nodes in accordance with the trust level obtained. The simulation test results show that MBC can find the malicious nodes more accurately and promptly that leads to the more effectively secure routing than the existing method.
