  To meet the growing local and distributed computing needs, the cloud is now
descending to the network edge and sometimes to user equipments. This approach
aims at distributing computing, data processing, and networking services closer
to the end users. Instead of concentrating data and computation in a small
number of large clouds, many edge systems are envisioned to be deployed close
to the end users or where computing and intelligent networking can best meet
user needs. In this paper, we go further converging such massively distributed
computing systems with multiple radio accesses. We propose an architecture
called MUREN (Multi-Radio Edge Node) for managing traffic in future mobile edge
networks. Our solution is based on the Mobile Edge Cloud (MEC) architecture and
its close interaction with Software Defined Networking (SDN), the whole jointly
interacting with Software-Defined Radios (SDR). We have implemented our
architecture in a proof of concept and tested it with two edge scenarios. Our
experiments show that centralizing the intelligence in the MEC allows to
guarantee the requirements of the edge services either by adapting the waveform
parameters, or through changing the radio interface or even by reconfiguring
the applications. More generally, the best decision can be seen as the optimal
reaction to the wireless links variations
