A multi-node communication network may include a plurality of nodes, which may include normal value nodes, a clusterhead node, and a high value node. Each of the plurality of nodes may include a communication interface and a controller. The high value node may be defined as high value relative to the normal value nodes during mission data fill. The high value node may be configured to locate the clusterhead node, register the high value node's membership to the clusterhead node, and send position-location information (PLI) to the clusterhead node during registration. Upon receipt of a PLI request, each of the normal value nodes may be configured to send current PLI to the clusterhead node. Upon receipt of the PLI request, the high value node may remain silent.

Stealth position-location information for high value nodes

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

The present disclosure is directed to a system and method for applying unique routing rules to encrypted data packets being transmitted via a tunneling protocol. Because encrypted data packets are unintelligible at intermediary points along a secured link or 'tunnel,' a multi-path router located between the tunnel endpoints is typically unable to apply unique routing rules. To enable unique routing, the disclosed method relies on a unique identifier that is associated with the secured link established between an initiator and a receiver (i.e., the tunnel endpoints). The unique identifier is transmitted with one or more encrypted data packets and is used at intermediary points to differentiate the encrypted data packets so that unique routing rules can be applied.
