N2 - The communication industry is envisioning ubiquitous connectivity as a crucial driving force in 5G. Next Generation Network (NGN) should interconnect, integrate and efficiently manage the enterprise networks to realize this vision. Efficient management and an always-on connectivity with seamless mobility across multiple radio access technologies are the paramount requirements of NGN. Media Independent Handover (MIH) is a well-known protocol for providing seamless mobility in Heterogeneous Networks (Het-Net) but it imposes a critical requirement of implementing MIH Function (MIHF) in every intermediate entity. This prerequisite, in turn, results in a complex flow sequence of control messages between the intermediaries, causing significant signaling overhead, which ultimately results in higher handover delay and packet loss. Moreover, the lack of centralized strategy for control forwarding across HetNet results in intricate handover procedures. To address these problems, we propose SD-MONET: Software Defined Mobility Management in Enterprise HetNet. SD-MONET is a Software Defined Networking (SDN) based architecture to realize fast and seamless mobility across WiFi and cellular networks, by minimizing the handover signaling overhead. By reducing the number of intermediaries, our analytical model achieves 40% reduction in the signaling overhead compared to an SDN-MIH based handover management scheme.
