2.1 Introduction

Cyber-physical systems (CPSs) aim at realizing the integration of computations with the physical world (Lee, 2008). The core idea of CPSs is the monitoring and controlling of physical objects through interconnected software systems, thereby blurring the boundaries between the physical world and the digital world. CPSs are deeply rooted in the well-established vision of ubiquitous computing (Weiser, 1991) and sensor networks (Akyildiz et al., 2002). The concept of CPSs has many similarities to the vision of the Internet of Things (Atzori et al., 2010; Ziegeldorf et al., 2014a). However, CPSs focus more on the interaction of smart objects with the physical world and less on the pervasive interconnection of such objects. The vision of CPSs is brought forward by several technological trends ranging from the increasing availability of low-cost, low-power, small form-factor computing and sensing devices to huge improvements in wireless communication and abundant Internet bandwidth (Rajkumar et al., 2010).

CPSs attest to the potential to drive innovation and competition in a wide range of sectors, ranging from energy and transportation over building automation and manufacturing to health and elderly care (Khaitan and ...
