Evaluation of QoS in RF/Li-Fi hybrid networks on 5th generation environments

This paper evaluates the most relevant scenarios in which establishing QoS parameters on RF/Li-Fi hybrid networks is necessary. The objective is to determine the improvement possibilities provided by this technology and realistically value its development potential, specifically for services in real time. We reviewed the alternatives in Internet of Things (IoT), applications, load balancing, scenarios of 5th generation, wireless sensors, and security, in addition to simulations and architectures of technology interoperability

Security for 5G Mobile Wireless Networks

The advanced features of 5G mobile wireless network systems yield new security requirements and challenges. This paper presents a comprehensive survey on security of 5G wireless network systems compared to the traditional cellular networks. The paper starts with a review on 5G wireless networks particularities as well as on the new requirements and motivations of 5G wireless security. The potential attacks and security services with the consideration of new service requirements and new use cases in 5G wireless networks are then summarized. The recent development and the existing schemes for the 5G wireless security are presented based on the corresponding security services including authentication, availability, data confidentiality, key management and privacy. The paper further discusses the new security features involving different technologies applied to 5G such as heterogeneous networks, device-to-device communications, massive multiple-input multiple-output, software defined networks and Internet of Things. Motivated by these security research and development activities, we propose a new 5G wireless security architecture, based on which the analysis of identity management and flexible authentication is provided. As a case study, we explore a handover procedure as well as a signaling load scheme to show the advantage of the proposed security architecture. The challenges and future directions of 5G wireless security are finally summarized
