Mobility management in cellular networks, such as the Long Term Evolution (LTE) System, relies on a centralized anchor, which depends on both the control plane and data plane. Therefore, mobility management suffers from many limitations such as low scalability and a single point of failure. Distributed Mobility Management (DMM) overcomes previous limitations and can be applied for HetNets or DenseNets. In this paper, we propose Three-Tiered Software Defined Networking (SDN)-based DMM to solve mobility problems and handover in DenseNets such as femtocells, in addition to macrocells. Our proposal reduces overhead signaling through the core network. As a result, it decreases delay and increases throughput over other cellular networks.
