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 by deploying multiple devices computing storage capabilities at the edge network, close to end-users. MEC enhances network efficiency reducing latency, enabling real-time awareness local environment, allowing cloud offloading, traffic congestion. New mission-critical applications require high security dependability, which are rarely addressed alongside performance. This survey paper fills this gap presenting 5G MEC’s three aspects: security, provides an overview MEC, introduces taxonomy, state-of-the-art, challenges related each aspect. Finally, presents jointly addressing aspects.
