Survivability of mobile and wireless communication networks by using service oriented Software Defined Network based Heterogeneous Inter-Domain Handoff system

Internet of Things (IoT) is one of the heterogeneous network consists of vast number of connected devices. These networks need smart architecture to accommodate the expected increase of data generation. Software-Defined Networks (SDN) have gained popularity as a key enabler for automated provisioning and ease in IoT network resources management. For ubiquitous coverage, these network involve seamless handoff of the user devices ensuring the provision the services as per user demand. Although the basic inter-domain handoff rules exist in the next SDN domain are not sufficient to provide the primary domain services to the IoT networks. This issue leads to degradation of post-handover performance. In this paper, the SDN based Heterogeneous Inter-Domain Handoff system for IoT (SDN-HIIoT) is proposed that enables SDN-Controller to exchange flow rules by using the East/West application programming interface. The proposed system is using a process of hybrid flow rules execution on heterogeneous SDN domain for provision of Quality of Services (QoS) to mobile users the same as the primary domain. Experiment results are provided to demonstrate the proposed system can significantly improve the post-handoff performance and provides ubiquitous services.
