  The fast growth of Internet-connected embedded devices demands for new
capabilities at the network edge. These new capabilities are local processing,
efficient communications, and resource virtualization. The current work aims to
address these capabilities by designing and deploying a new management
proposal, which offers on-demand activation of offline Internet of Things (IoT)
fog computing assets via a Software Defined Networking (SDN) based solution
combined with containerization and sensor virtualization. We propose a testbed
as a proof of concept for the main functionalities of this novel solution. The
obtained results evidence that the current SDN-based solution can deploy with
success activation policies on computational edge containers, which are located
within the same network domain of the SDN controller. In addition, different
application-level scenarios are also investigated.
