Fast and Seamless Handover in Software Defined Vehicular Networks

Tele-operated driving is a transition phase to the deployment of fully autonomous cars. Vehicles are supposed to communicate with a remote control station in order to exchange surrounding videos and location information. This communication is achieved through a vehicular network, and it requires low latency and high reliability. To this end, the handover management should be studied carefully. This paper devises a mobility management scheme for vehicular networks based on the Software Defined Networking (SDN) paradigm. The proposed scheme provides handover anticipation in order to guarantee a low-latency and a seamless handover. In addition, it proposes a strategy that aims at reducing control signaling overhead and network congestion. Performance analysis show that our approach reduces handover delays and losses.
