receiving, by the SDN controller from the first moving node, a confirmation message indicating that the modification of the physical network topology parameter has been executed; and

sending, by the SDN controller, the second control message responsive to receiving the confirmation message.

13. The method of claim 8 , wherein sending the first control message includes sending instructions to cause the first moving node to modify at least one parameter associated with a transmitter of the first moving node.

14. The method of claim 13 , wherein sending the first control message includes sending instructions to cause the first moving node to modify at least one of a transmission power, a transmission frequency, and a modulation scheme.

15. A non-transitory computer-readable medium having instructions encoded thereon which, when executed by one or more processors, cause the one or more processors to perform a method for configuring a software-defined network (SDN), the method comprising:

sending, by an SDN controller communicatively coupled to a plurality of moving nodes, a first control message to a first moving node of the plurality of moving nodes according to a control-to-data-plane interface (CDPI) protocol, the first control message including instructions for the first moving node to execute a modification of a physical network topology parameter, including at least instructions to cause the first moving node to aim a wireless transceiver towards a second moving node; and

sending, by the SDN controller, a second control message to the first moving node according to the CDPI protocol, the second control message including instructions for the first moving node to modify routing information stored by the first moving node based on the modification of the physical network topology parameter.
