LightEdge: Mapping the Evolution of Multi-Access Edge Computing in Cellular Networks.

The MEC paradigm calls for a distribution of computational capacity at the network's edges. While MEC will play a key role in future 5G deployments, it will take some time until the existing 4G networks evolve into a full 5G system. A challenge exists to devise a transition mechanism that allows MEC features to be seamlessly integrated in the current 4G networks. This article introduces a lightwei...
