Abstract : Outlier detection is the process of identifying the data objects that do not comply with the normal behavior of the defined data model. Used in automated data analysis, it ensures the desired data quality and reliability. This field has attracted increasing attention in the wireless sensor network domain, using methods from machine learning, data mining, and statistics literature. In this paper, we propose a novel outlier detection approach based on Copula theory. This powerful theory enables modeling the dependency between data measurements in a formal and statistical way.We have evaluated our proposed approach with a real world dataset. Our results show a detection rate of 85.90% and an error rate of 0.87% .
