With the continuous growth of the number of mobile devices connected to the Internet, cellular network infrastructure owners are facing several new challenges. The fifth generation of mobile technology (5G) is planned to enable a fully mobile and connected society and to empower socio-economic transformations. In 5G, different scenarios with high and strict requirements are being deployed. To deal with such heterogeneity, more advanced communication services are required. Network Function Virtualization (NFV) combined with distributed micro data centers (MDCs) can improve the management of the data flows through several 5G base stations. On the one hand, NFV provides high scalability without requiring significant architectural changes; and on the other hand, distributed MDCs decentralize architecture management, bringing the computational capabilities nearer to the base stations, hence reducing …
