Abstract:We consider the problem of identifying the insider-based attacks in the form of jammers in multi-channel wireless networks, 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. Starting from such a simple concept, we develop an alibi framework to cope with insider-based jamming attackers in various situations including single jammer, lossy channels, non-colluding jammers and colluding jammers. We evaluate the framework according to several properties such as accuracy, detection time & network performance in ns2 simulation and analysis. The overall results of these protocols show a promising research direction to deal with insider-based jamming attacks.
