Context-aware source reliability estimation for multi-sensor management

摘要

Large-scale pervasive systems deal with situations that are characterized by their stochastic environment and dynamic nature. Sensor Management (SM) literature to date is based on an optimistic assumption about the reliability of the underlying models producing the beliefs associated with imperfect data. Nonetheless, different models usually have different reliabilities and are only valid for a specific sensing range. To address these shortcomings, a novel methodology for estimation of source information reliability based on contextual information of the sensor setting and environment dynamics is proposed. The proposed approach enhances the source information reliability and the detection ratio in an energy efficient manner.
