Modeling and Mitigating Errors in Belief Propagation for Distributed Detection
Younes Abdi, Tapani Ristaniemi
We study the behavior of the belief-propagation (BP) algorithm affected by erroneous data exchange in a wireless sensor network (WSN). The WSN conducts a distributed binary hypothe…
Optimization of the Belief-Propagation Algorithm for Distributed Detection by Linear Data-Fusion Techniques
Younes Abdi, Tapani Ristaniemi
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 tha…
The Max-Product Algorithm Viewed as Linear Data-Fusion: A Distributed Detection Scenario
Younes Abdi, Tapani Ristaniemi
In this paper, we disclose the statistical behavior of the max-product algorithm configured to solve a maximum a posteriori (MAP) estimation problem in a network of distributed age…
Random Interruptions in Cooperation for Spectrum Sensing in Cognitive Radio Networks
Younes Abdi, Tapani Ristaniemi
In this paper, a new cooperation structure for spectrum sensing in cognitive radio networks is proposed which outperforms the existing commonly-used ones in terms of energy efficie…
