Information systems are becoming more integrated into our lives. As this integration deepens, the importance of securing these systems increases. Because of lower installation and maintenance costs, many of these systems are largely networked by wireless means. In order to identify gaps and propose research directions in wireless network intrusion detection research, we survey the literature of this area. Our approach is to classify existing contemporary wireless intrusion detection system (IDS) techniques based on target wireless network, detection technique, collection process, trust model and analysis technique. We summarize pros and cons of the same or different types of concerns and considerations for wireless intrusion detection with respect to specific attributes of target wireless networks including wireless local area networks (WLANs), wireless personal area networks (WPANs), wireless sensor networks (WSNs), ad hoc networks, mobile telephony, wireless mesh networks (WMNs) and cyber physical systems (CPSs). Next, we summarize the most and least studied wireless IDS techniques in the literature, identify research gaps, and analyze the rationale for the degree of their treatment. Finally, we identify worthy but little explored topics and provide suggestions for ways to conduct research.
