Characteristics and classification of outlier detection techniques for wireless sensor networks in harsh environments: a survey

TL;DR: A survey of the essential characteristics for the analysis of outlier detection techniques in harsh environments, which include, input data type, spatio-temporal and attribute correlations, user specified thresholds, outlier types, type of approach, and susceptibility to dynamic topology, non-stationarity and inhomogeneity are presented.
Journal ArticleDOI

A WSN for Monitoring and Event Reporting in Underground Mine Environments

TL;DR: A WSN-based system capable of detecting and identifying events of interest and localization of miners and roof falls and a novel energy-efficient hybrid communication protocol using both periodic and aperiodic modes of communication while adhering to low latency requirement for emergency situations is proposed and implemented.
Journal ArticleDOI

One-class support vector machines: analysis of outlier detection for wireless sensor networks in harsh environments

TL;DR: This work presents a detailed analysis of various formulations of one-class SVMs, like,hyper-plane, hyper-Sphere, quarter-sphere and hyper-ellipsoidal, used to separate the normal data from anomalous data in Wireless Sensor Networks.
