1. A system, comprising:
a mobile ad-hoc network (MANET) including a plurality of nodes, wherein each of the plurality of nodes comprises a communication interface and a controller, wherein the plurality of nodes comprises beacon-based clusterhead (BB-CH) nodes and members, wherein each of the plurality of nodes is one of a BB-CH node or a member of at least one BB-CH node, wherein each of the plurality of nodes is configured to transmit communication data packets and transmit beacons, wherein a range of each beacon is greater than a range of each communication data packet, wherein each of the plurality of nodes has passive spatial awareness,
wherein, for each of the BB-CH nodes having members, a BB-CH node is configured to compile spatial awareness information via passive spatial awareness (PSA) based at least on a beacon from each member of the members of the BB-CH node, wherein the spatial awareness information from a given member of the members includes information of a member identification of the given member, wherein the compiled spatial awareness information includes a BB-CH node identification for the BB-CH node, position-location information (PLI) of the BB-CH node, a quantity of the members of the BB-CH node, and a member list including member identifications of the members,
wherein, for each of the BB-CH nodes, the BB-CH node is configured to broadcast, via efficient flooding, at least some of the compiled spatial awareness information to every connected node of the plurality of nodes.
