A novel approach to identify insider-based jamming attacks in multi-channel wireless networks

We consider the problem of identifying the insider-based attacks in the form of jammers in a single-hop wireless network, where jammers have the inside knowledge of frequency hopping patterns and any protocols used in the wireless network. We propose a novel technique, called “alibi”, to identify the insider-based jammers in multi-channel wireless networks. Alibi is a form of defense whereby a defendant attempts to prove that he or she was elsewhere when the crime in question was committed. From this concept, we propose two alibi-based protocols to demonstrate how to identify insider-based jammers using alibi techniques. We show several important properties of these protocols such as completeness, accuracy & detection speed in ns2 simulation and analysis. The overall results of these protocols show a promising research direction to deal with insider-based jamming attacks.
