Capabilities of Low-Power Wireless Jammers
— In this paper, motivated by the goal of modeling the fine-grain capabilities of jammers for the context of security in low-power wireless networks, we experimentally characterize jamming in networks of CC2420 radio motes and CC1000 radio motes. Our findings include that it is easy to locate J (relative to S and R) and choose its power level so that J can corrupt S’s messages with high probability as well as corrupt individual S’s bits with nontrivial probability. Internal jammers are however limited in at least two ways: One, it is hard for them to prevent R from detecting that it has received an uncorrupted message from S. And two, the outcome of their corruptions are not only not deterministic, even the probabilities of corrupted outcomes are time-varying. We therefore conclude that it is hard to predict the value resulting from colliding S’s messages (bits) with J’s messages (bits) and, conversely, to deduce the value sent by S’s or J’s from the corrupted value rec...
