SDN aided Mobility Management for Connected Vehicle Networks

Connected Vehicle is provided with the Internet access with built-in modems providing onboard 4G LTE and allows to share Wi-Fi Internet access with other mobile devices both internal and external vehicle. The large volume of data is possibly transmitted over the Internet through the connected services or infotainment service by passengers. From the origin to destination on the road, the connected vehicle may frequently change its point attachment with high speed, leading to a large number of packet loss impact on quality of experience (QoE). To address this problem, in this paper, we propose a new mobility management approach with the benefits of Software-Defined Networking (SDN) for prediction and pre-uploading the data to next Road Side Unit (RSU) in vehicular networks.
