The Evolution of IDs Solutions in Wireless Ad-Hoc Networks to Wireless Mesh Networks
The domain of wireless networks is inherently vulnerable to attacks due to the unreliable wireless medium. Such networks can be secured from intrusions using either prevention or detection schemes. This paper focuses its study on intrusion detection rather than prevention of attacks. As attackers keep on improvising too, an active prevention method alone cannot provide total security to the system. Here in lies the importance of Intrusion Detection Systems (IDS) that are solely designed to detect intrusions in real time. Wireless networks are broadly classified into Wireless Ad-Hoc Networks (WAHNs), Mobile Adhoc NETworks (MANETs), Wireless Sensor Networks (WSNs) and the most recent Wireless Mesh Networks (WMNs).
