Cyber-Physical Systems, also known as CPS, are nowadays widespread systems and consequently a widely researched topic. They are used to describe systems with decision making capacities integrated into the real world through a combination of sensors and actuators. Different types of CPS exist but we will focus on a particular one, the Smart Home, which is a fast growing application of CPSs. Smart Home systems and generally Smart Devices are used to increase the quality of life, comfort, and ability of remote controlling the home. The topic will be thoroughly researched and analysed in order to gain complete and extensive knowledge on the most common types of Smart Home systems and the devices and protocols that they typically use.
