Interference-Resilient Information Exchange
—This paper presents an efficient protocol to reliably exchange information in a single-hop radio network with unpredictable interference. The devices can access C communication channels. We model the interference with an adversary that can disrupt up to t of these channels simultaneously. We assume no shared secret keys or third-party infrastructure. The running time of our protocol decreases as the gap between C and t increases. Two extreme cases prove particularly interesting: The running time is linear when the number of channels C = Ω(t2 ), and exponential when only C = t + 1 channels are available. We prove that exponential-time is unavoidable in the latter case. At the core of our protocol lies a combinatorial function, of independent interest, and described for the first time in this paper: the multi-selector. This function determines a sequence of device channel assignments such that every sufficiently large subset of devices is partitioned, by at least one of these ass...
