Secure IP Mobility Support in Software Defined Networks

With the proliferation of mobile device and applications, a large number of mobility management solutions have been proposed to support mobility in IP networks. Mobile IP and its derivatives are basically network layer solutions for terminal mobility problems. However, there are several shortages in those solutions, such as large overhead, high latency, lack of scalability and weak security. Software Defined Networking (SDN) provides a flexible centralized approach to handle mobility in IP networks. In this paper, we propose a network based secure mobility management architecture. SDN controller manages the mobility with full authority and controls OpenFlow Switches to forward packets for mobile nodes in optimal path. The implementation and test results show a better delay and throughput performance during the handover process.
