Abstract

The Fifth Generation (5G) of mobile networks offers new and advanced services with stricter requirements. Multi-access Edge Computing (MEC) is a key technology that enables these new services by deploying multiple devices with computing and storage capabilities at the edge of the network, close to end-users. MEC enhances network efficiency by reducing latency, enabling real-time awareness of the local environment, allowing cloud offloading, and reducing traffic congestion. New mission-critical applications require high security and dependability, which are rarely addressed alongside performance. This survey paper fills this gap by presenting 5G MEC's three aspects: security, dependability, and performance. The paper provides an overview of MEC, introduces taxonomy, state-of-the-art, and challenges related to each aspect. Finally, the paper presents the challenges of jointly addressing these three aspects., Comment: 39 pages, 12 figures, 15 tables. This paper is published at IEEE Access (https://ieeexplore.ieee.org/document/10158694)

16. Experimental Evaluation of Handover Strategies in 5G-MEC Scenario by using AdvantEDGE

Abstract

The 5G-MEC architecture increases the heterogene-ity and dynamicity of the available resources, presenting unique and competing challenges to researchers, network designers, and application developers. Recent studies indicate AdvantEDGE as an interesting emulation platform to investigate these challenges. The paper presents a particular example of AdvantEDGE usage. A testbed composed of the emulated 5G-MEC architecture and the VideoLAN application allows to analyse the performance of alternative handover strategies, developed by using a multi-objective approach. The study shows how AdvantEDGE allows a deep analysis of the behaviour of the different strategies during the emulated user mobility, giving the possibility of measuring performance parameters at different layers, i.e. IP, application, and end-user.

33. MigraMEC: Hybrid Testbed for MEC App Migration.

Abstract

Multi-access Edge Computing (MEC) enhances the capabilities of 5G by enabling the computation closer to the end-user for real-time and context-aware services. One of the main challenges of MEC is the migration of the MEC application in the presence of user mobility. MigraMEC is a hybrid testbed that simulates the network scenario and user mobility and emulates the MEC framework by using AdvantEDGE. Moreover, MigraMEC implements two physical MEC Hosts (MEHs) by using an extended version of Kubernetes (K8s). Finally, the MigraMEC controller interacts with both the emulative and experimental environments to ensure an efficient migration of the MEC application. Based on network information, the MigraMEC controller not only enforces the MEH where the MEC application is running but also the Point of Access (PoA) to which the user is connected. In our demonstration, the MEC application is a video streaming service, and the results highlight the need for multiple MEHs and efficient migration to maintain a high user experience.

Abstract

The fifth generation (5G) of cellular networks promises to be a major step in the evolution of wireless technology. 5G is planned to be used in a very broad set of application scenarios. These scenarios have strict heterogeneous requirements that will be accomplished by enhancements on the radio access network and a collection of innovative wireless technologies. Softwarization technologies, such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV), will play a key role in integrating these different technologies. Network slicing emerges as a cost-efficient solution for the implementation of the diverse 5G requirements and verticals. The 5G radio access and core networks will be based on a SDN/NFV infrastructure, which will be able to orchestrate the resources and control the network in order to efficiently and flexibly and with scalability provide network services. In this paper, we present the up-to-date status of the software-defined 5G radio access and core networks and a broad range of future research challenges on the orchestration and control aspects.
