MOBILITY MANAGEMENT IN A CROSS-DOMAIN SDN ARCHITECTURE LEVERAGING THE IPV6 MOBILE PROXY

Mobility and technology have become inseparable terms in the sense that users want to stay connected and continue to use their services while moving. The various technologies that manage mobility face fundamental challenges such as optimizing intra-domain and inter-domain routes.With the emergence of Software-Defined Networking (SDN), a promising technology that separates the control plane from the data plane in network devices, mobility management could benefit from its advantages and thus address the above challenges. In this paper, we propose a new method of communication during the movement of a mobile node between two different domains based on the operation of the PMIPv6 protocol in a software defined networking (SDN) architecture and the involvement of edge nodes to anticipate the new destination of the mobile node. The proposed method is inspired by proactive and reactive inter-domain handovers and allows the controller to anticipate inter-domain communication with its peers and simultaneously reduce the handover time in the visited domain and the data transfer delay. The experimental results confirmed the effectiveness of the proposed method.
