Abstract:Abstract-We introduce a generative model, dubbed I/O HSMM, for learning the bi-modal behavioral dynamics of a network of cognitive radios (CRs). Each of the two modes of the CRs is represented as a Hidden Semi-Markov model (HSMM), where the states, state durations and emissions, transition probabilities between states, and transitions between modes are uncovered based solely on RF spectrum sensing. The learning of the CR dynamics is non-parametric and derived from the Hierarchical Dirichlet Process (HDP), with… Show more
