SDN Based Fast Handover over IP Mobility

SDN (Software Defined Networking) has been promised as a next information transport infrastructure. Some SDN solutions have been deployed due to their benefits of features and functions. Recently, mobility management in SDN has been being studied and proposed to expand SDN functionalities. However, some limitations of those proposed schemes were reported, for example, they demonstrated with few of SDN switches and flows. IP mobility is a key of mobility management in SDN. In this paper, we propose fast hand over IP mobility for SDN. We present how the signal flow works, to make a better data flow for mobile devices. Our solution eliminates tunneling procedure and takes the advantage from a centralized controller that helps to decrease a protocol complexity. We give the evaluate result of our solution in terms of handover delay, overhead cost and packet loss. We have evaluated in both Intra-domain and Inter-domain mobility. We have shown that our scheme performs better than others.
