Due to advances in technology, research in healthcare using a cyber-physical system (CPS) opens innovative dimensions of services. In this paper, the authors propose an energy- and service-level agreement (SLA)-efficient cyber physical system for E-healthcare during data transmission services. Furthermore, the proposed phenomenon will be enhanced to ensure the security by detecting and eliminating the malicious devices/nodes involved during the communication process through advances in the ad hoc on-demand distance vector (AODV) protocol. The proposed framework addresses the two security threats, such as grey and black holes, that severely affect network services. Furthermore, the proposed framework used to find the different network metrics such as average qualifying service set (QSS) paths, mean hop and energy efficiency of the quickest path. The framework is simulated by calculating the above metrics in mutual cases i.e., without the contribution of malevolent nodes and with the contribution of malevolent nodes over service time, hop count and energy constraints. Further, variation of SLA and energy shows their expediency in the selection of efficient network metrics.

Risk Assessment Models

This paper involved the computation of quickest paths with the help of service-level agreement (SLA) and energy constraints. The consideration of these constraints helps to propose a novel system model which computes the path to strengthen the continuity and criticality of the data transmission. The proposed risk-energy aware SLA provisioning (RESP) system model incorporates the research gaps of the existing risk assessment models in the literature without any increase in time complexity. The formulation of RESP shows the usefulness in the critical applications. The results show that the computation of risk-provisioned path gives the SLA satisfied paths and has a great impact of variations in the data traffic. The performance of the proposed algorithm has been indicated in terms of different performance parameters such as mean s−t paths, average hop counts, and average energy efficiency. Simulation result implies that as data traffic increases, the number of the risk‐provisioned s−t paths decreases whereas corresponding average hop counts and average energy efficiency increases.

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.

Wireless ad-hoc mesh network is a special kind of network, where all of the nodes move in time. Node is intended to help relaying packets of neighboring nodes using multi-hop routing mechanism in order to solve problem of dead communication. Wireless mesh network which engages broadcasting and contains multiple hops become increasingly vulnerable to problems such as routing problem and rapid increasing of overhead packets. During this progress, the delay on account of multi hop characteristics and redundant packets caused by communication nature potentially existed during communication. Typically, delay will increase in linearity with number of hops. There is a certain minimum level of delay that will be experienced due to the time it takes to transmit a packet through a link. Topology development holds a significant point prior to the data transmission. Without improved topology development protocol, this problem can decrease network’s performance in overall data transmission. We analyze the delay performance of a multi-hop wireless network with a dynamic route between each source and final destination pair. There are fluctuate interference constraints on the set of links that impose a fundamental delay performance of any instant network topology. At first, we present a similar Link State Routing network simulation to derive such referential lower bounds. We conduct extensive simulation studies to suggest that the average delay of multi-hop transmission policy can be made lower compared to the referential bound by using appropriate functions of network metrics. This paper provides a broadcast framework that engages various network metrics and at the same time maintaining connectivity of nodes (mobile terminals). The framework captures the essential features of the wireless network metrics, i.e. bandwidth, throughput, network buffer, direction, and round trip time. This research is useful since, in many cases, it find that the throughput is the most important parameter in reduction of delay transmission. This result is confirmed with another composite simulation result. Most of network hop delay is impacted with this composite metric, particularly in delay minimization on the longer hops. The reduction achievement on average delay by this algorithm is 0.577% and the total average delay reduction for this simulated network is 0.683%. This research will be further designed primarily for achieving maximum throughput in the multiple wireless network area.

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.

New Research

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.
