Reliable efficient flooding with Doppler nulling (spatial awareness)

A system comprising:

• a receiver node configured to be used in a mobile ad-hoc network (MANET), the receiver node comprising:
• a communications interface comprising at least one antenna element;
• and
• a controller operatively coupled to the communications interface, the controller including one or more processors, wherein the controller has information of own node velocity and own node orientation relative to a common reference frame;
• wherein the receiver node is time synchronized to apply Doppler corrections associated with the receiver node's own motions relative to the common reference frame,
• wherein the common reference frame is known to the receiver node prior to the receiver node receiving signals from a transmitter node,
• wherein the receiver node is configured to process the signals according to the Doppler corrections to the signals applied using Doppler null steering along a plurality of Null directions based on the transmitter node's own motions,
• wherein, based on a spatial awareness of the MANET determined via the signals based on the Doppler null steering, the receiver node is configured to:
• flood a communication data packet to a destination node based on the spatial awareness.
