Intrusion Detection in Ad-hoc Networks

The rapid increase of wireless networks and mobile computing applications has changed the landscape of networks security. The traditional way to protect networks with firewalls and encryption software is no longer sufficient and effective. We need to search for new techniques to protect the wireless networks and mobile computing application. In this paper, we introduce the demands of ad-hoc environment. We focus on two areas of ad-hoc networks, wireless firewall and wireless intrusion detection. Furthermore, we particularly analyze the architecture, the problems and the challenges of current IDS techniques for wireless ad-hoc networks.
