Wireless Connectivity of CPS for Smart Manufacturing: A Survey

Fourth Industrial revolution (Industry 4.0) has entirely reshaped the landscape of the global world from both enterprise and academia aspect. In the mean-time Cyber-Physical System (CPS) has proven its existence by effectively monitoring, analyzing, automating and communicating with every corner. So, wireless connectivity in the industrial world is considered as the challenging issues to be tackled. Sensor based technologies in association with wireless communication are playing main role in Industry 4.0 and CPS environment to make the whole world as smart, sharp and dynamic place. Thus, smart factories must be built by introducing the sensor enabled communication entities such as, CPS, Wireless Sensor Networks (WSNs) with strong and reliable network connection. So, this paper selects the suitable wireless connectivity in Industry 4.0 by focusing at network metrics for instance, latency, reliability, longevity, and throughput. Besides, the critical wireless needs of the CPS based Industry 4.0 are observed and verified through rigorous literature than wireless network and communication technology is proposed from the pool of classical methods. That proposed wireless networks and technology will lead to the future CPS problems in the light of any standard.
