A Review on Handover Mechanisms in Software Defined Networks

With Software-Defined Networking (SDN) is considered promising to simplify network management and enable research innovations based on the decomposition of the control and data planes. Wireless networks require specific features such as mobility management, dynamic channel configuration, and rapid client re-association [1]. In cases which require some extension to an existing wired topology, and there is little motivation to make fundamental changes to the existing topology, Wireless Software-defined Networks (SDWN) can be used. The key difference between SDN and traditional networking is infrastructure: SDN is software-based, while traditional networking is hardware-based. Because the control plane is software-based, SDN is much more flexible than traditional networking. It allows administrators to control the network, change configuration settings, provision resources, and increase network capacity. This paper presents a review on the handover mechanism among software defined networks.
