A game-theoretic intrusion detection model for mobile ad hoc networks

In this paper, we address the problem of increasing the effectiveness of an intrusion detection system (IDS) for a cluster of nodes in ad hoc networks. To reduce the performance overhead of the IDS, a leader node is usually elected to handle the intrusion detection service on behalf of the whole cluster. However, most current solutions elect a leader randomly without considering the resource level of nodes. Such a solution will cause nodes with less remaining resources to die faster, reducing the overall lifetime of the cluster. It is also vulnerable to selfish nodes who do not provide services to others while at the same time benefiting from such services. Our experiments show that the presence of selfish nodes can significantly reduce the effectiveness of an IDS because less packets are inspected over time. To increase the effectiveness of an IDS in MANET, we propose a unified framework that is able to: (1) Balance the resource consumption among all the nodes and thus increase the o...
