Design and Performance Evaluation of a Lightweight Wireless Early Warning Intrusion Detection Prototype

The proliferation of wireless networks has been remarkable during the last decade. The license-free nature of the ISM band along with the rapid proliferation of the Wi-Fi-enabled devices, especially the smart phones, has substantially increased the demand for broadband wireless access. However, due to their open nature, wireless networks are susceptible to a number of attacks. In this paper, the authors present anomaly-based intrusion detection algorithms for the detection of three types of attacks: attacks performed on the same channel legitimate clients use for communication, attacks on neighbouring channels, and severe attacks that completely block network's operation.
