Processing Streaming Human Trajectories with WSO2 CEP

Extracting useful information from an inaccurate data stream is a significant issue in data stream processing for IoT applications. This article describes the use of Kalman filters to smooth human trajectory information gathered from an iBeacon sensor network and demonstrates its effectiveness. The solution has been built with WSO2 CEP, a complex event processing middleware.
