Cyber-Physical Systems (CPSs) are a new study area that has the potential to bring together the physical and digital worlds. Researchers in this study focus on the ways in which CPSs communicate with one other. Features and requirements for data transfer in CPSs, and also related unsolved issues, are covered in this paper. The IEEE 802.11 b/g protocols were used to construct a CPS solution for ambient sensing (humidity and temperature). Wireless Fidelity (Wi- Fi) sensors that can connect to a preexisting Wireless LAN and servers that provides access to data collected everywhere IEEE 802.11 b/g networks connectivity is available and from any Internet-connected device are required for this method.
