Wireless Network Intrusion Detection System: Techniques, Systems and Future Challenges

Our daily lives are gradually getting more and more permeated by information technology. It becomes more crucial to protect these systems as their interconnectedness expands. Most of these systems are now networked wirelessly since doing so reduces the time and money required for both installation and maintenance. We conduct a literature review to locate knowledge gaps and suggest future research objectives in the field of wireless network intrusion detection. We take a methodical approach to categorising current wireless IDS methods according to their respective levels of sophistication, scope of coverage, target wireless network, data gathering procedure, trust model, and analysis method. In this article, we provide a concise overview of the benefits and drawbacks of various approaches to wireless intrusion detection, taking into account the unique characteristics of various wireless networks like WLANs, WPANs, WSNs, ad hoc networks, mobile telephony, WMNs, and cyber physical systems (CPSs). We then provide a brief overview of the most and least explored wireless IDS strategies, highlight the gaps in the current research, and critically examine the reasoning behind the varying levels of attention paid to each. We conclude by pointing out areas deserving of further study that have received relatively little attention and offering suggestions for doing so.
