FOUNDS Seminar Series Talk 02 - Loosing control and interfering

Talk Abstract : In dense networks, with objects that are expected to operate for several years without maintenance, access to resources can no longer be provided in a globally coordinated way. Nor is it possible or efficient to completely orthogonalize communications. Releasing control, however, will mean an increase in interference, at least some of which will have to be treated as noise. We are interested in the statistical properties of this noise. A Gaussian model is not suitable. Instead, we propose heavy-tailed distributions, which are particularly well-suited to representing the rare but highly penalizing cases of strong interference. The dependence between the different elements of an interference vector is then a key characteristic that needs to be modelled, copulas being a possible way forward.
