State of the art: Fog computing for 5G networks

5G will enable the future Internet of Everything (IoE) paradigm, where devices, terminals, machines, and also smart things and robots will become innovative tools that will produce and use applications, services and data. However, future Internet will exacerbate the need for improved QoS/OoE, supported by services that are orchestrated on-demand and that are capable to adapt at runtime depending on the contextual conditions, to allow reduced latency, high mobility, high scalability and real time execution. A new paradigm called Fog Computing has emerged to meet these requirements. It extends Cloud Computing to the network edge, allowing low latency, load balancing and flexible mobility support, and showing as a promising solution for 5G network. This paper evaluates Fog Computing service orchestration as a support mechanism for 5G Network in terms of round trip time latency.
