Semantic IoT: Theory and Applications

2021

In the coming few years, there is going to be rapid advancement in terms of technology like 5G, 6G, etc. When we think about 5G, the performance of the internet is going to increase multifold. The 5G i.e. fifth-generation network is going to be very heterogeneous. There is a need for a standardized solution to the issues in this technology. In this work, we are trying to understand the problems specifically in IoT (Internet of Things) area of 5G. In the literature survey, we found out that various solutions have been proposed in the area of the Internet of Things, but there is a lack of some generic solutions for all IoT projects. Every project works excellent in its closed and specified environment. When we try to connect multiple IoT projects, there is a big problem of interoperability. Some ICT standardization organizations have proposed some solutions to interoperability to overcome this scenario. Few solutions have been proposed by some authors to provide interoperability using semantic technologies. The solution for this problem of heterogeneous IoT can be provided using the semantic technologies in combination with that of SDN (Software Defined Network), NFV (Network Function Virtualization), and Cloud infrastructure.

Semantic IoT: Theory and Applications

2021

“…Current cellular networks will not be sufficient to handle the enormous amount of increase in data traffic required 2 . 5G is characterized by 100% availability, up to 10‐year increase in devices' battery life, 90% reduction in network power consumption, and connectivity throughput up to 10 Gbps 3 . Moreover in Kaneriya et al, 4 they explored the possibility of full‐duplex 5G communications for monitoring systems in the sphere of ambient assisted living (AAL) which simplify and automate processes that do not require human intervention.…”

“…Physical‐layer security (PLS), an interesting wireless security approach for 5G networks, can mitigate physical‐layer threats using multiple wireless techniques such as massive multiple‐input‐multiple‐output (mMIMO), non‐orthogonal‐multiple‐access (NOMA), millimeter wave (mmWave), and visible light communication (VLC) (Figure 2). PLS is an optimal security approach for 5G wireless networks for its lower computational complexity and larger scalability 3 . Physical‐layer threats are primarily divided into two categories, based on the purpose of the attacker, passive and active attacks which include jamming, contaminating, eavesdropping, and spoofing.…”

Visible light communication (VLC) is considered to be a great replacement or complement to existing radio frequency networks to provide the future fifthgeneration (5G) wireless technology with higher data rates for indoor connectivity, which alleviates the traffic demand. Therefore, many issues emerged regarding the security in 5G networks as human safety is at risk. This work presents a comprehensive study on the physical-layer security (PLS) and solutions in 5G networks, specifically, the security of VLC technology as one of the core PLS solutions for 5G future wireless networks. Furthermore, VLC threats and PLS solutions are extensively investigated. Based on our study, we propose a new indoor VLC secure model to enhance the secrecy performance in VLC networks using a combination of multiple PLS techniques to achieve this aim as beamforming, secure communication zones, and friendly jamming. The simulation results with respect to the received optical power and signal-tonoise ratio (SNR) prove that the proposed indoor VLC model can improve the secrecy performance. As the user's SNR exceeded 100 dB and optical received power reached 15 mW, the malicious user's SNR barely reached 30 dB with a 4-μW received power outside the target zone increasing his interference level.Finally, future research directions in VLC security are outlined to encourage future research.

“…The statement above defines it as a more open and independent system that benefits in terms of content transfer and interaction, but it also possesses challenges like the need of more bandwidth for transfer of massive content as well as low latency and security. IoT is an open network in terms of devices connected as any node is malicious to another node which rises trust and privacy issue in IoT [1][2][3]. Currently, IoT is deployed on current technology 4G that lacks the inability to address the challenges of IoT specifically bandwidth and privacy [4].…”

et al. 2021

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.
