Hypothesis Testing Over Multi-hop and Noisy Networks

In this talk, coding and testing schemes for hypothesis testing over multi-hop networks are presented. The schemes are based on unanimous decision forwarding where the terminals decide on the null hypothesis if all previous terminals have decided on this hypothesis and they forward their decisions to the next terminal. The proposed coding and testing schemes are shown to achieve the optimal type-II error exponent region for some special cases of testing against independence. The proposed schemes are further improved by means of binning. The improved schemes are analyzed using Han’s approach and shown to be optimal for a special case of testing against conditional independence. An extension of this analysis to hypothesis testing over a noisy channel is also discussed.
