A system may include a transmitter node and a receiver node. Each node may include a communications interface including 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. Each node may be time synchronized to apply Doppler corrections associated with said node's own motions relative to a common reference frame. The common reference frame may be known to the transmitter node and the receiver node prior to the transmitter node transmitting signals to the receiver node. The receiver node may be an autonomous vehicle. The receiver node may be configured to identify a risk of a potential collision with the transmitter node based on the signals.

Spatial awareness navigation techniques on unmanned aerial vehicles (spatial awareness)

A communication node of a multi-node communication network is disclosed. The communication node includes a communication interface and a controller. The controller is configured to receive a data packet, via the communication interface, from a first additional communication node, the data packet including a broadcast address indicative of a clustering status of the first additional communication node. The controller is further configured to determine a clustering status of the communication node, the clustering status based on a relationship between a number of gateway nodes and a number of clusterhead nodes communicatively coupled to the communication node. The controller is further configured to transmit the data packet, via the communication interface, to at least a second additional communication node if the determined clustering status is a gateway clustering status or a clusterhead clustering status, the data packet including a broadcast address indicative of the clustering status of the communication node.

Zero-overhead efficient flooding

A communication node of a multi-node communication network includes a communication interface and a controller. In embodiments, the controller is configured to: receive a data packet from a first additional communication node; determine if the data packet comprises a time-sensitive data packet; determine if a length of the data packet is less than a length threshold; transmit the data packet via a conventional routing procedure to at least one second additional communication node of the multi-node communication network if the data packet comprises a non-time-sensitive data packet or if the length of the data packet is greater than the data packet length threshold; and transmit the data packet via a packet flooding procedure to the at least one second additional communication node if the data packet comprises a time-sensitive data packet and if the length of the data packet is less than the length threshold.

Zero-overhead data initiated AnyCasting

In embodiments, a communication node of a multi-node communication network includes a communication interface and a controller communicatively coupled to the communication interface. In embodiments, the controller is configured to receive a first data packet transmitted from a source communication node to a destination communication node; transmit the first data packet via a packet flooding procedure; receive a first route response transmitted from the destination communication node along a discovered route; relay an additional data packet transmitted from the source communication node to the destination communication node along the discovered route; determine a route failure of the additional data packet; re-transmit the additional data packet to the destination communication node via a packet flooding procedure; receive an additional route response transmitted from the destination communication node along a recovered route; and relay a second additional data packet transmitted from the source communication node along the recovered route.

Flooding to routing

A method of performing data frame error recovery is disclosed. A data packet is received and tested to determine whether the data packet includes one or more bit errors. The data packet is compared with one or more data packets stored in a recovery buffer to identify a duplicate of the data packet when the data packet includes one or more bit errors. One or more bits affected by the one or more bit errors are identified based on a comparison between the data packet and the duplicate of the data packet. Different combinations of bit values for the one or more bits are determined, and the data packet is tested with the different combinations to identify a correct combination of bit values for the one or more bits. The data packet is recovered based on the correct combination of bit values for the one or more bits.
