In energy detection-based cognitive radio (CR), the conventional transmission strategy
consists in comparing the measured energy to a predefined threshold. Then, while the …

We design an optimal non-uniform quantizer for collaborative spectrum sensing (CSS) in
cognitive radio networks (CRNs). We assume non-ideal reporting channels are and consist …

Internet of Things (IoT) systems will increasingly rely on energy harvested from their
environment, and energy harvesting (EH) techniques necessitate a rethinking of how we …

In this paper, we disclose the statistical behavior of the max-product algorithm configured to
solve a maximum a posteriori estimation problem in a network of distributed agents …

To detect the presence of primary users, spectrum sensing is considered as one of the most
important and basic functions of cognitive radio. To improve the detection probability in …

In this paper, we investigate distributed inference schemes, over binary-valued Markov
random fields, which are realized by the belief propagation (BP) algorithm. We first show that …

Introducing random interruptions in the cooperation of the sensing nodes with the fusion
center is a new approach to increase the efficiency of the centralized cooperative spectrum …

Interrupted reporting has recently been introduced as an effective method to increase the
energy efficiency of cooperative spectrum sensing schemes in cognitive radio networks. In …
