Handover support is one of the important issues in mobile networks to guarantee the quality of service (QoS) requirements for mobile users. Alongside the development of network technologies, handover management to provide service continuity has been researched and applied for the Internet or cellular networks such as 3G/4G/5G. However, each network paradigm provides its own individual handover management system, even though there are different kinds of QoS requirements for various mobile services. This causes inefficient network resource utilization from the network operators’ perspectives. Therefore, this paper proposes a QoS-aware flexible mobility management scheme for software-defined networking (SDN)-based mobile networks. The proposed scheme classifies flows into four classes based on the QoS requirements of services in terms of delay and loss tolerance. According to the classified service characteristics, it provides a differential handover method for each flow class to support efficient network operation without any service degradation by interacting between the forwarding plane nodes and SDN controller. The performance analysis shows that the proposed scheme enables flexible network resource utilization, satisfying the QoS requirements for each class well compared to the conventional schemes that only consider their own individual handover procedure.

Handover Scheme

Delay and packet loss caused by the basic mobile IPv6 handover protocol can not guarantee the service quality of real-time communication. In order to improve the performance of fast handover of the mobile IPv6, we proposed a fast handover scheme based on hierarchical mobility which combines micro mobility and the link layer trigger. By shielding local mobility of the mobile node, the scheme can greatly reduce the signaling information traffic from mobile node to HA and CN. Through the link layer trigger mechanism, the scheme builds a tunnel in advance to avoid packet loss. In order to verify the performance of the proposed scheme, we did some simulation experiments in the NS-2 environment. The simulation results show that the scheme reduces handover delay and packet loss effectively.
