In this paper, we address the issue of privacy in 5th generation (5G) driven
Internet of Things (IoT) and related technologies while presenting a comparison
with previous technologies for communication and unaddressed issues in 5G.
Initially, an overview of 5G driven IoT is presented with details about both
technologies and eventually leading to problems that 5th generation will face.
Details about 5G are also presented while comparing them with previous
technologies. The architecture of 5G is presented hence explaining layers of 5G
and technologies like SDN, NFV and cloud computing that compose these layers.
The architecture for 5g based IoT is also presented for providing visual
understanding as well as explained based on how this addresses the issues
present in 4G. Privacy is highlighted in 5G driven IoT while providing details
about how SDN, NFV and cloud computing helps in elimination of this issue. The
issues presented will be compared with 4G based IoT and solutions are provided
about mitigation of these issues particularly bandwidth and security. Moreover,
techniques used by 4G and 5G technologies for handling the issues of privacy in
IoT are presented in a nutshell as a table. Paper also presents a detailed
overview of technologies making 5G possible meanwhile giving an explanation
about how these technologies resolve privacy issues in 5G.
