Abstract

The way we use and access the Internet has been changing since its creation, evolving to more dynamic traffic patterns and following new consumption trends such as IP video in mobile scenarios. New requirements towards the underlying network rise, particularly regarding to mobility management support in wireless heterogeneous environments. In this sense, 5G network architectures have begun development empowered by key technologies such as Software Defined Networks (SDN). Progressing from wired-only deployment, SDN has recently become the target of research in wireless environments, with its signalling reaching the mobile node and involving it in the mobility process. It thus becomes important to assess the impact of SDN for mobility management, under different conditions. This is where this work contributes: it presents a framework using SDN as the mobility management protocol where the content source is mobile, evaluating handover delay and the impact of different threshold configurations for triggering mobility in both network and mobile initiated scenarios. Results showcase the feasibility of the proposed framework, evidencing the impact of OpenFlow in MN deployment.
