Cloud-Edge Computing for Cyber-Physical Systems and Internet-of-Things

Abstract : This Special Section on ‘`Cloud-Edge Computing for Cyber-Physical Systems and Internet-of-Things’' is oriented to the dissemination of a few of those latest research and innovation results, covering many aspects of design, optimization, implementation, and evaluation of emerging cloud-edge solutions for CPS and IoT applications. The selected high-quality contributions cover a broad range of novel technologies and application scenarios in CPS and IoT. We hope that these accepted papers will produce long-lasting impacts, as well as stimulating and encouraging the international community to work on this exciting and impactful topic.

 EXISTING SYSTEM :

 ? The Internet-of-Things (IoT) has also enjoyed widespread adoption, mostly for its ability to add “sensing” and “actuation” capabilities to existing CPS infrastructures. ? In such an environment, domain-dependent components are separated from the layers that leverage existing middleware frameworks. ? As suggested earlier, the existing CTPs may have a varied impact on CPS dependability of sensitive or non-sensitive applications. ? For the various experiments, Cooja’s existing profiling tools were used. For time sensitive experiments, both the simulation timers and node real-time timers were used to ensure accuracy.

 DISADVANTAGE :

 ? As measurements and data collection physically at customer buildings is a generic and repeating task in building diagnostic service provisioning, the problem is approached from the general utility viewpoint. ? The unified management of computing and communication resources within horizontally integrated distributed edge computing infrastructure is a research problem and design challenge in enabling scalable provisioning of edge computing infrastructure. ? OpenVPN was experimented as a solution to the problem, but the connectivity problem remained unsolved. ? Due to the inherent complexity of the technical systems realizing cyber-physical digital service, evolution of the digital infrastructure has central role in facilitating cyber-physical digital service provisioning.

 PROPOSED SYSTEM :

 • In, a microscopic mathematical model is proposed to describe the propagation dynamics of the sensor worm in Wireless Sensor and Actuator Networks (WSAN) in situations where actuator mobility causes sensor worms to spread faster. • In, a model formulated by differential equations is proposed to explain the process of worm propagation in WSNs. • In , the authors proposed a cyber-physical management that includes a holistic controller that generates actuation signals for WSAN re-configuring for performance control. • Autonomic computing provides the potential to transform the CPS of the future into a computing environment that can manage itself through a feedback loop using the MAPE structure initially proposed by IBM.

 ADVANTAGE :

 ? In cyber-physical digital service provisioning the spatiotemporal interaction requirements between service actors and resources, as well as performance of those, become central for the design of value proposition and service interaction. ? Accordingly, cost efficient, dynamic and scalable on-demand provisioning of cyber-physical digital service is not feasible in the current state of the digital infrastructure. ? However further research is needed on cyber-physical digital service engineering methods, architectures and provisioning of the related technology and computing infrastructure, in order to enable efficient, high quality and scalable design, development, operation and governance of cyberphysical digital service.
