**2.5 Reducing bandwidth and power consumption**

Both bandwidth and power consumption of the numerous number of devices that are connecting, communicating, and sharing data among each other through the Internet of Things are tremendously increased. This is why when designing an Internet of Things infrastructure, both bandwidth and power consumption challenges should be considered. The main trend nowadays is to reduce the size of the connected devices,

Sharing data and connecting devices together through the Internet of Things can be implemented through several levels and layers of software/hardware and some standard protocols. With the tremendous increase in the shared data and connected devices, the used software/hardware and standard protocols will be more complicated. As a result, there is a challenge to reduce the complexity of the Internet of

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
