Baids: Detection of Blackhole Attack in Manet by Specialized Mobile Agent

Abstract

The inbuilt flexibility along with easy set-up and low maintenance cost causes MANETs to be increasingly useful in catastrophe management, battlefield surveillance; etc. The infrastructure-less performance of MANET has made it more vulnerable to intrusion than ever before making the security of network all the more acute. As the previously used security systems fail to protect the MANET from insider attacks, the need for an Intrusion Detection System (IDS) becomes evident. IDS based on Mobile Agents is long been used for securing the MANET. The prior works seem to suffer from computational overhead leading to performance. This paper proposes a mobile agent based IDS in order to reduce the overheads. The use of distributed ID consists of multiple mobile agents which assist over a large network and to make communication with each other, or with a central server that provide advanced network monitoring, incident analysis, and instant attack data. This as a whole reduces the network bandwidth usage by moving data analysis computation to the place of the intrusion data & sustains on the heterogeneous platforms.
