The fifth-generation mobile initiative, 5G, is a tremendous and collective effort to specify, standardize, design, manufacture, and deploy the next cellular network generation. 5G networks will support demanding services such as enhanced Mobile Broadband, Ultra-Reliable and Low Latency Communications and massive Machine-Type Communications, which will require data rates of tens of Gbps, latencies of few milliseconds and connection densities of millions of devices per square kilometer. This survey presents the most significant use cases expected for 5G including their corresponding scenarios and traffic models. First, the paper analyzes the characteristics and requirements for 5G communications, considering aspects such as traffic volume, network deployments, and main performance targets. Secondly, emphasizing the definition of performance evaluation criteria for 5G technologies, the paper reviews related proposals from principal standards development organizations and industry alliances. Finally, well-defined and significant 5G use cases are provided. As a result, these guidelines will help and ease the performance evaluation of current and future 5G innovations, as well as the dimensioning of 5G future deployments.

“…The orchestration of a network slice spanning across multiple administrative domains is also a challenge that has been tentatively faced by proposing 3GPP-based hierarchical architecture [49]. Many architectures have been suggested, for example, 5G-NORMA proposed a MANO called Software-Defined Mobile Network Orchestrator (SDM-O), which is composed of an inter-slice resource broker for crossslice resource allocation and slice-specific NFV orchestrators [50].…”

“…Management rights granted to tenants must be treated with care especially when several tenants share common resources and network functions. For this purpose, the 5G-NORMA architecture includes two main controllers, Software-Defined Mobile Network Coordinator (SDM-X) for the control of common (shared) network functions and Software-Defined Mobile Network Controller (SDM-C) for dedicated network functions [50].…”

The fifth-generation (5G) of cellular networks is currently under deployment by network operators, and new 5G end-user devices are about to be commercialized by many manufacturers. This is just a first step in the 5G's development, and the true potential of 5G is still far from being reached. Currently, one of the main 5G technologies under the interest of the research community is the network slicing. Network slicing will allow exploiting the 5G infrastructure to flexibly and efficiently provide heterogeneous services (e.g., voice communication, video streaming, e-health, vehicular communication). Like every new technology, one of the critical aspects that need to be considered is the security. In this article, we spotlight the security in 5G network slicing. We highlight threats and recommendations, which are presented in terms of life-cycle security, intra-slice security, and inter-slice security. Furthermore, we identify and discuss open security issues related to network slicing. INDEX TERMS 5G, Network Slicing, Security.

“…The authors used a controller to offer application-oriented resource concept of the fundamental RAN. An ability broker for resource slices was presented first by the Third Generation Partnership Project (3GPP) and widely assessed in [27] by allowing on-demand slice resource allocation. The infrastructure provider instantiates a network slice by allocating precise resources to a Mobile Virtual Network Operator (MVNO), service providers, and vertical parts for a stated time duration.…”

Network slicing is a promising technology for 5G networks in which operators can sell customized services to different tenants at various prices and Quality of Services (QoS) demands. Thus, the latest 4th Generation (4G) and upcoming 5th Generation (5G) mobile technologies are expected to offer massive connectivity and management of high volume of data traffic in the presence of immense interferences from mobile networks of IoT devices. Further, it will face challenges of congestion and overload of data traffic due to the humongous number of IoT devices. Nevertheless, these devices are likely to demand high throughput, low latency, and high level of reliability especially for critical real-time applications such as in Vehicular Communication System (VCS). To address these issues in 5G mobile networks, this paper proposes a Slice Allocation Management (SAM) Model based on the critical services of smart systems such as VCS to satisfy QoS demands. The proposed model aims at providing dedicated slices on the basis of service requirements such as expected throughput and latency for VCS. To ensure such performance and provide data traffic priorities of IoT devices in the uplink of Relay Nodes (RNs) cells in the 5G mobile networks, we have sliced the Radio Access Networks (RAN), along with the assignment of the nearest Mobile Edge Computing (MEC) with isolated slices based on the priorities for each IoT nodes to reduce latency level. The proposed model was simulated and validated using the OPNET simulator. The results obtained demonstrate that SAM Model is able to achieve improvement of end to end delays and uplink throughputs of the networks in high-density networks of IoT devices.
