Fifth Generation (5G) networks hold the promise of features and performance levels that is going to put the conventional cellular communication paradigm through rigorous challenges. This paper presents a novel architecture for a 5G network which will be capable of mobile device centric communication regardless of the presence of a Base Station (BS). The major contribution of this paper, lies in the proposed system and protocol design of a Device-to-Device (D2D) communication system for 5G mobile system. The proposed design has two sub-categories – (a) fully device centric and (b) partially device centric. Additionally, the devices have been designed to communicate independently or with partial dependency on support from the BS. The system has been simulated under various parameters. The simulation results showcased in this paper highlights the efficiency and effectiveness of the proposed design.

The fifth generation (5G) network is expected to be flexible to satisfy quality of service (QoS) requirements, and the software-defined network (SDN) with network slicing will be a good approach for admission control. In this paper, the authors present and compare two fuzzy-based schemes to evaluate the QoS (FSQoS). They call these schemes FSQoS1 and FSQoS2. The FSQoS1 considers three parameters: slice throughput (ST), slice delay (SD), and slice loss (SL). In FSQoS2, they consider as an additional parameter the slice reliability (SR). So, FSQoS2 has four input parameters. They carried out simulations for evaluating the performance of the proposed schemes. From simulation results, they conclude that the considered parameters have different effects on the QoS performance. The FSQoS2 is more complex than FSQoS1, but it has a better performance for evaluating QoS. When ST and SR are increasing, the QoS parameter is increased. But, when SD and SL are increasing, the QoS is decreased. When ST is 0.1, SD is 0.1, SL is 0.1, and the QoS is increased by 32.02% when SR is increased from 0.3 to 0.8.

This research work presents a power control mechanism developed for ProSe-enabled sensors so that the sensors can be smoothly integrated into the fifth generation (5G) of mobile networks. It is strongly anticipated that 5G networks will provide an enabling environment for the 21st century innovations like the internet of things (IoT). Sensors are pivotal in IoT. The proposed power control mechanism involves an open loop power control (OLPC) mechanism that a ProSe-enabled sensor has to use to establish communication with a base station (BS) and a closed loop power control (CLPC) the BS then has use to establish transmit power levels for devices to be involved in a device to device (D2D) communication depending on the prevailing channel conditions. The results obtained demonstrate that the developed scheme does not adversely affect the quality of service (QoS) of a 5G mobile network.

The continuous development of fifth-generation (5G) networks is the main driving force for the growth of Internet of Things (IoT) applications. It is expected that the 5G network will greatly expand the applications of the IoT, thereby promoting the operation of cellular networks, the security and network challenges of the IoT, and pushing the future of the Internet to the edge. Because the IoT can make anything in anyplace be connected together at any time, it can provide ubiquitous services. With the establishment and use of 5G wireless networks, the cellular IoT (CIoT) will be developed and applied. In order to provide more reliable CIoT applications, a reliable network topology is very important. Reaching a consensus is one of the most important issues in providing a highly reliable CIoT design. Therefore, it is necessary to reach a consensus so that even if some components in the system is abnormal, the application in the system can still execute correctly in CIoT. In this study, a protocol of consensus is discussed in CIoT with dual abnormality mode that combines dormant abnormality and malicious abnormality. The protocol proposed in this research not only allows all normal components in CIoT to reach a consensus with the minimum times of data exchange, but also allows the maximum number of dormant and malicious abnormal components in CIoT. In the meantime, the protocol can make all normal components in CIoT satisfy the constraints of reaching consensus: Termination, Agreement, and Integrity.

This paper presents radio frequency (RF) capacity estimation for millimeter wave (mm-wave) based fifth-generation (5G) cellular networks using field-level simulations. It is shown that, by reducing antenna beamwidth from 65° to 30°, we can enhance the capacity of mm-wave cellular networks roughly by 3.0 times at a distance of 220 m from the base station (BS). This enhancement is far much higher than the corresponding enhancement of 1.2 times observed for 900 MHz and 2.6 GHz microwave networks at the same distance from the BS. Thus the use of narrow beamwidth transmitting antennas has more pronounced benefits in mm-wave networks. Deployment trials performed on an LTE TDD site operating on 2.6 GHz show that 6-sector site with 27° antenna beamwidth enhances the quality of service (QoS) roughly by 40% and more than doubles the overall BS throughput (while enhancing the per sector throughput 1.1 times on average) compared to a 3-sector site using 65° antenna beamwidth. This agrees well with our capacity simulations. Since mm-wave 5G networks will use arbitrary number of beams, with beamwidth much less than 30°, the capacity enhancement expected in 5G system when using narrow beamwidth antennas would be much more than three times observed in our simulations.

The article is devoted to the analysis of electromagnetic radiation of fifth generation (5G) networks. The characteristic of the 5G electromagnetic radiation spectrum and its features is given. The main advantages of implementing 5G networks proceeding from the Concept of the Ministry of communications of Russia are analyzed, including the Internet of Things, artificial intelligence, augmented, extended reality, and virtual reality. Nine ways in which 5G and IoT will cause serious harm to people, wildlife, and our Earth are summarized. The conclusions of the Concept are being questioned. The article analyzes the results that the military personnel is expecting from the 5G network, including the introduction of hypersonic weapons, the creation of "smart military bases", "combat networks", the use of "portable combat items", drones, non-lethal, directed energy electronic weapons. It is justified: how does 5G differ qualitatively and quantitatively from 4G in its impact on human health. Based on the appeal of scientists and environmental organizations from 219 countries to the UN, the WTO, the EU, the Council of Europe and the governments of all States, the demand for the immediate termination of the deployment of a 5G wireless network on Earth and in space is justified.

This case demonstrates the utility of the 3Es (effectiveness, efficiency, and equity) in examining Reducing Emissions from Deforestation and Forest Degradation (REDD+) project in Nepal. REDD+ offers results-based payments for conserving and managing forests sustainably and enhancing forest carbon stocks. This will benefit communities’ efforts to conserve forest resources and prevent deforestation; conserving integrity of forests in turn benefits the global carbon budget. This case uses the 3Es to examine one case in Nepal of distributing the REDD+ funds among local participants. Of the 3Es, equity is getting attention worldwide but there is still debate on which principle of 3Es should be given priority to achieve overall effectiveness of REDD+. This case finds that equity is a fundamental requirement to achieve the other Es (efficiency and effectiveness) in REDD+ implementation. Further, I find that distributive equity is the most important and understood in three different ways in Nepal: rights, needs, and performance. There is an argument between communities and experts on which equity should be given priority. I recommend that the issue of needs based equity vs. performance-based equity should be solved by formation of guidelines of sharing benefits at two levels. First, the benefit distribution from international sources/markets to community forest user groups should be based on the ownership of carbon and performance of communities participating in REDD+. Second, at community level, communities should decide on the form of benefit distribution according to their needs. The primacy of equity in this case will likely find international echoes in other environmental policies and in other countries.
