Introduction

Abstract

The emergence of nontrivial embedded sensor units (e.g., those embedded in smartphones and other everyday appliances), networked embedded systems, and sensor/actuator networks (e.g., those associated with services running on mobiles and wireless sensor networks) has made possible the design and implementation of several sophisticated applications where large amounts of real-time data are collected to constitute a big data picture as time passes. Acquired data are then processed at local, cluster-of-units or server level to take the appropriate actions or make the most appropriate decision.
