**3. Internet of Things applications**

The Internet of Things is recognized as one of the most important areas of future technologies and is gaining vast recognition in a wide range of applications and fields related to smart cities, military, education, hospitals, homeland security systems, transportation and autonomous connected cars, agriculture, intelligent shopping systems, and other modern technologies. The smart home is one of the main applications that use the Internet of Things infrastructure to connect several sensors. The sensors can sense and collect surrounding information that is used to fully control different home systems such as lighting and security as seen in **Figure 3**.

There are many other applications that use the Internet of Things infrastructures such as smart bridges and smart tunnels. Temperature and vibration sensors, as well as video surveillance cameras, can be fixed on a bridge to detect any abnormal

activity and send warnings via SMS. Also video processing analysis can be performed to control the traffic density on a bridge. The smart tunnel can use several sensors to monitor humidity, displacement, and temperature to call for appropriate maintenance if a problem is detected. All of these applications are using sensors to detect and collect data that are used to give a proper decision that maintains a high level of security of the installations.
