Optimal Mobile Sensing and Actuation Policies in Cyber-physical Systems
A successful cyber-physical system, a complex interweaving of hardware and software in direct interaction with some parts of the physical environment, relies heavily on proper identification of the, often pre-existing, physical elements. Based on informat

Preface
Cyber-physical systems (CPSs) are an emerging research topic born from the ever increasing complexity of engineered systems. Future systems will have to interact with each other and with the physical world in a very tight and wellcoordinated fashion, and designing such systems is the research challenge behind CPSs. CPSs have been defined as “computational thinking and integration of computation around the physical dynamic systems where sensing, decision, actuation, computation, networking, and physical processes are mixed”. Given such a definition of CPSs, it is trivial to observe that there are two main entities in a CPS: the “cyber” end of the system that is composed of the hardware and software, and the “physical” end of the system that relates to part of the environment. The problem of designing the cyber part may not be trivial but can be solved from scratch. However, the physical part, usually a natural physical process, is inherently given and has to be identified in order to propose an appropriate cyber part to be adopted. Therefore, one of the first steps in designing a CPS is to identify its physical part. The physical part can belong to a large array of system classes. A
