Fifth generation (5G) mobile networks will lead to a deep integration between networks and applications. Through novel paradigms like Network Functions Virtualization (NFV) and Edge Computing, new classes of heterogeneous application services will be enabled to run close to mobile end-user devices with zero-perceived latency and fully-cognitive...

By bringing Cloud-like services much closer to endusers and their devices, Fog computing is foreseen to expand the scope of overlay networks, encompassing different heterogeneity dimensions (i.e., size, geographical distribution, devices/virtual objects (VOs) involved, quality of service (QoS) requirements, etc.). Although highly flexible...

The upcoming Cloud-Fog interplay is expected to grant service providers more degrees of freedom in the implementation and management of their service portfolios. However, recent advances in Mobile Internet have developed a growing need to support user mobility - as users move, the Fog counterparts of services that require close proximity may...

In the virtualized environment of 5G networks, the control and management of dynamic network slices poses a set of challenges that are still largely unsolved. Though the architectural framework and the elements of abstraction and orchestration mechanisms have been defined, the dynamic orchestration of resources based on them entails the...

In the last few years, network "softwarization" is gaining increasing popularity to achieve dynamicity and flexibility. Cloud computing, as well as the new paradigms of Software Defined Networking (SDN) and Network Functions Virtualization (NFV), are supporting this evolution. However, the need to move services closer to users to guarantee low...
