Internet of Things (IoT) has become the inevitable component in smart city
development. The decline in the workforce of developing countries is presently
solved through cyber-physical system (CPS) technology. The industries are enabled
with CPS to monitor their production, enhancing their productivity through Industry
4.0 standards. The main objective of Industry 4.0 is to integrate all the machines as
a single integrated network for M2M communication. The CPS is enabled in autonomous robots, UAVs, cybersecurity, cloud storage systems, additive manufacturing, augmented realities, and big data computations. The production became noticeable during Industry 3.0 standards; however, the microcomputer interface and machineto-machine interaction in Industry 4.0 have made a tremendous increase in production. Industry 4.0 has decentralized analytics, critical decision making, and increase in response time during productions.
