A MADM-based Handover Management in Software-defined 5G Network

The network densification is one of the key components of 5G to satisfying high data traffic. However, dense deployment of small cells introduces numerous challenges. Such as frequent handovers, inconsistent, interfaces, and so on. The software-defined 5G network is one important technique to solve these problems. Due to the separation of control plane and data plane, the handover management also should be redesigned in layers. In the paper, we have proposed a handover management strategy based on Multiple Attribute Decision Making (MADM) in Software-defined 5G network. The handover operations are managed by the handover controller in control plane. According to the simulation results, the proposed handover management strategy has the less delays and handover failure ratios than the conventional LTE1.
