On the Scalability of a Cyber Physical System

Kumar Padmanabh


Sensors and actuators are the fundamental constituents of a cyber physical system (CPS). Every sensors are ought to produce data. The pervasiveness of sensors, the requirement of collaborative processing of data, the historical importance of data and ever increasing different forms of user applications are not only making the data management more complex, they are also bringing more challenges in the scalability of the CPS. On the other hand, the requirement of bringing actuators to complete the feedback loop of a CPS is making it even more complex. There are three stages of complexities associated with the scalability of a CPS: firstly in the physical infrastructure of the data acquisition system, secondly in the communication mechanism and thirdly in the server and user applications. In all these three stages, the diversity, interoperability and individual capacity limitations of components play an important role in establishing the overall scalability limits of the CPS. In this paper we will systematically study how these parameters are affecting the scalability limits. Furthermore, we will also study the other existing technologies (e.g. of big data and cloud) which can be used for addressing the challenges of scalability imposed at different stages of futuristic cyber physical systems.
