Forgive me for asking this question.
I am trying to see how SDN paradigm can be applied to highly dynamic networks, i.e., vehicular networks. If we consider vehicles as edges in a network, (i.e., the edge is moving itself), then how can we report a vehicular geographical position back to a localized SDN controller or a centralized SDN controller?
Even if we store the vehicle's geographical location in a flowtable, wouldn't it add to a significant SDN Management Overhead? Also, what would happen if one of the localized SDN controllers fails and the centralized SDN controller would loose the globalized view of the network ... is there any alternate arrangement where the disconnected networks relies temporarily?
