This paper presents a brief survey of current research in intrusion detection for wireless ad-hoc networks. In addition to examining the challenges of providing intrusion detection in this environment, this paper reviews current efforts to detect attacks against the ad-hoc routing infrastructure, as well as detecting attacks directed against the mobile nodes. This paper also examines the intrusion detection architectures that may be deployed for different wireless ad-hoc network infrastructures, as well as proposed methods of intrusion response.
