Detection and analysis of black hole attack using IDS

Abstract

Mobile Ad-hoc Network (MANET) has no clear line of defense; i.e., no built-in security. Black hole attack found in network layer pretends that it has a shortest route to reach to the destination but actually consumes all the packets sent by the source. In this paper, Intrusion Detection System is implemented using NS-2 by modifying the original AODV protocol and removing the black hole node which drops the maximum packets. We also proposed a method of activating the promiscuous mode by selecting the path of highest sequence number which is helpful in achieving the better Quality of Services (QoS). The study was conducted to analyze the performance of the IDS technique over existing techniques which revealed that the Packet Delivery Ratio is improved by 60%.
