Software Defined Networking (SDN) is seen as one of the underlying mechanisms of the next generation telecommunications architecture (i.e., 5G networks). Despite SDN being
deployed at the core and back-haul of the mobile network, its usage directly over the wireless mobile terminals has been disregarded, as well as the possibilities for novel control procedures in wireless nodes. Using the OpenFlow protocol, an instantiation of
SDN, this study extends the SDN mechanisms all the way to the mobile node in heterogeneous wireless environments, enabling the mobile node to assist the controller entity in the flow-based mobility procedure. The concept framework was implemented over a physical wireless testbed, validating its contribution in a mobile source-mobility use case, with results highlighting the promising benefits of extending SDN approaches for end-to-end flow control in wireless environments.
