This paper formulates wireless sensor networks (WSNs) fault diagnosis problem as a pattern-classification problem and introduces a newly developed algorithm, neighborhood hidden conditional random field (NHCRF), for determining hidden states between sensors. The health conditions of WSN are determined by using the NHCRF model to estimate the posterior probability of different faulty scenarios. The...
Wireless sensor networks are widely deployed in different industrial applications. Fault diagnosis of sensors is essential for maintaining a robust WSN operation. In this paper, we show faulty sensors diagnosis can be transformed into a pattern classification problem. We also introduce an efficient algorithm, called, Neighborhood Hidden Conditional Random Field, to recognize sensor states and the...
Wireless sensor network (WSN) has become widely used in different applications. Fault detection of sensors is importance for maintaining a reliable WSN operation. And identification of faulty nodes in a WSN can be transformed into a pattern classification problem. In this paper, we introduce an effective label propagation procedure using semi-supervised local kernel density estimation. The proposed...
