Distributed hierarchical IDS for MANET over AODV+

In this paper, we introduce background knowledge of wireless ad hoc network in mobile ad hoc networks (MANET) as well as intrusion detection systems (IDS) and mobile agents. This research study surveys, studies and compares the existing intrusion detection based on mobile agent for mobile ad hoc networks. Based on our best knowledge from previous researches we design distributed hierarchical IDS inclusive of network-based and host-based intrusion detection system with due consideration to their characteristics on ad hoc on-demand distance vector routing protocol (AODV+). In addition, distributed hierarchical IDS model consists of two layers, cluster member layer and cluster head layer. Designing distributed hierarchical IDS is the main part of our methodology, where we try to show some improvement for ideal and accurate IDS for wireless ad hoc network. We propose some enhancement based on the characteristics and measure the efficiency of IDS in term of accuracy and detection rate and CPU usage.
