Introduction
IoT is defined as a network of physical devices such as home appliances, electronic
components and other connectivity that enables these things to collect and share data. It
is an advanced technology in the field of communication that provides a platform to
connect two or more peripheral devices. It involves various kinds of networks and
devices such as laptops, desktops, smartphones and many more (Al-Fuqaha, et al.,
2015). The main aim of this report is to highlight the importance of IoT in this modern
generation and technologies and network protocols used by IoT for communication
purpose. It uses internet connectivity to interconnect two or more computing devices
and the main advantage of this technology is that users can send their data for long
distance. This report is explaining the concept of an internet of thing, communication
protocols used by IoT and technical challenges faced by this technology.
Data communication protocols
There are numbers of data communication protocols used by the internet of thing for
communication purpose which are the following:
 Satellite
 Wi-Fi
 Radiofrequency
 Bluetooth
 NFC
 RFID
Satellite
Satellite communication provides a platform to interconnect two or more mobile
networks which are located on a very long distance. In this type of network protocol, a
machine to machine communication is used because it connects two different computer
devices by using cell networks. Generally, IoT used this kind of system to produce a
large computer network which is used for long-distance communication (Da, et al.,
2014).
