5G Multi-Access Edge Computing: A Survey on Security, Dependability, and Performance

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.

Automated summary

The Fifth Generation (5G) of mobile networks is enhanced by Multi-access Edge Computing (MEC), which deploys devices with computing and storage capabilities at the network edge to provide new and advanced services. MEC improves network efficiency by reducing latency, enabling real-time awareness, allowing cloud offloading, and reducing congestion. This survey paper focuses on the security, dependability, and performance aspects of 5G MEC and presents an overview, taxonomy, state-of-the-art, and challenges related to each aspect.
