Within the last 20 years, wireless communication and network has been one of the fastest-growing research areas. Significant progress has been made in the fields of mobile ad hoc network (MANET) and wireless sensor networks (WSN). Very recently, the cyber-physical system (CPS) has emerged as a promising direction to enrich human-to-human, human to-object, and object-to-object interactions in the physical world as well as in the virtual world. The possibilities are enormous, such that CPS would adopt, and even nurture, the areas of MANET and WSN because more sensor inputs and richer network connectivity are required. The chapter reviews what has been developed in these fields, outlines the projection of what may happen in the field of CPS, and identifies further works. The authors identify the unique features of WSN, raising some CPS critical examples, and then directing the future challenges of CPS. In order to fully comprehend the connection of WSN to CPS, the authors provide some preliminaries of WSN and establish their necessary connections.

Like the other emerging technologies such as computer evolution and embedded machines, the Vehicular Ad Hoc Networks (VANETs) have also gained much attention from various manufactures and academia. Moreover, we have several on board sensors installed inside the vehicles, responsible for sensing different activities within the vehicle and surrounding such as temperature, intruder detection and so on. Recently, those sensors/actuator systems became responsive to the physical world by enabling real time control emanating from conventional embedded systems, thus emerging a new research paradigm named Cyber-Physical System (CPS). Likewise, other applications for CPS, we have Vehicular Cyber-Physical System (VCPS) that is not a new concept. For now, VCPS may refer to a wide range of transportation management system that is integrated strongly and should be highly accurate, real-time, and efficient. This chapter provides readers with the details of the term “VCPS” followed by the historical overview of this new emerging field including research challenges and future aspects of the VCPS.

Sensing, distributed computation and wireless communication are the essential building components of a Cyber-Physical System (CPS). Having many advantages such as mobility, low power, multi-hop routing, low latency, self-administration, utonomous data acquisition, and fault tolerance, Wireless Sensor Networks (WSNs) have gone beyond the scope of monitoring the environment and can be a way to support CPS. This paper presents the design, deployment, and empirical study of an eHealth system, which can remotely monitor vital signs from patients such as body temperature, blood pressure, SPO2, and heart rate. The primary contribution of this paper is the measurements of the proposed eHealth device that assesses the feasibility of WSNs for patient monitoring in hospitals in two aspects of communication and clinical sensing. Moreover, both simulation and experiment are used to investigate the performance of the design in many aspects such as networking reliability, sensing reliability, or end-to-end delay. The results show that the network achieved high reliability - nearly 97% while the sensing reliability of the vital signs can be obtained at approximately 98%. This indicates the feasibility and promise of using WSNs for continuous patient monitoring and clinical worsening detection in general hospital units.

Wireless Multi-Hop Networks (such as Mobile Ad hoc Networks, Wireless Sensor Networks, and Wireless Mesh Networks) promise improved flexibility, reliability, and performance compared to conventional Wireless Local Area Networks (WLAN) or sensor installations. They can be deployed quickly to provide network connectivity in areas without existing backbone/back-haul infrastructure, such as disaster areas, impassable terrain, or underserved communities. Due to their distributed nature, routing algorithms for these types of networks have to be self-organized. Ant routing is a bio-inspired self-organized method for routing, which is a promising approach for routing in such Wireless Multi-Hop Networks. This chapter provides an introduction to Wireless Multi-Hop Networks, their specific challenges, and an overview of the ant algorithms available for routing in such networks.

Security Issues

As cyber physical system security is not satisfactory, the security of a particular infrastructure depends on both internal and other related vulnerabilities. Communications between components in the cyber and physical realms lead to unintentional information flow. This chapter describes the difficult communications that occurs between the cyber and physical domains and their impact on security. Assailants may be competent to initiate exclusive attacks to cyber physical systems. There are several types of attacks that affect the interactions between the cyber and physical devices, which might be in a passive way or in an active method. Even though the communication provides authenticity and confidentiality, a few attacks form some threats against ad hoc routing protocols as well as location-based security systems. It has been said that many attacks modify the activities of the targeted control system.

The advances of the Internet of Things, robotics, and Artificial Intelligence, to give just a few examples, allow us to imagine promising results in the development of smart buildings in the near future. In the particular case of elderly care, there are new solutions that integrate systems that monitor variables associated with the health of each user or systems that facilitate physical or cognitive rehabilitation. In all these solutions, it is clear that these new environments, usually called Ambient Assisted Living (AAL), configure a Cyber-Physical System (CPS) that connects information from the physical world to the cyber-world with the primary objective of adding more intelligence to these environments. This article presents a CPS-AAL for caregiving centers, with the main novelty that includes a Socially Assistive Robot (SAR). The CPS-AAL presented in this work uses a digital twin world with the information acquired by all devices. The basis of this digital twin world is the CORTEX cognitive architecture, a set of software agents interacting through a Deep State Representation (DSR) that stored the shared information between them. The proposal is evaluated in a simulated environment with two use cases requiring interaction between the sensors and the SAR in a simulated caregiving center.

Cyber-physical system (CPS) is a multiple system where physical world operations are monitored and controlled by communication and computing components. This paper focuses on the framework, design and simulation of a CPS for public security applications. A framework of the CPS is presented, and its compositions are analyzed in detail. To meet the requirements of cyber-physical control, the design features of environment perception and communication are investigated. An improved task allocation method and a hybrid approach for path planning are introduced for robots coordination and optimization. Finally, the CPS is demonstrated with a case study in a public security scenario, where robots equipped with sensors cooperate with each other to extinguish fires arising due to a disaster. The simulation experiments are conducted to show the feasibility of such system.
