Patent Images

1. A system, comprising:

  • a set of nodes deployable across an area, the nodes being configured and operative to self-form a mobile ad-hoc network for communication there among, the set including nodes having (1) imaging circuitry by which a node captures an image of a respective local sub-area based on a triggering event, (2) image-transfer circuitry by which a node partitions a captured image into a plurality of sub-images and transmits the sub-images to respective other nodes via the mobile ad-hoc network, (3) image transmission circuitry by which a node transmits on a respective uplink a respective sub-image received from another node, the sub-images being transmitted with corresponding sub-image identifiers usable to reassemble the image from the sub images;

    a relay coupled to the nodes by respective uplinks, the uplinks used to communicate the sub-images and sub-image identifiers from the nodes to the relay, the relay being configured and operative, with multiple channels, to (1) receive transmissions of respective sub-images of a captured image, along with the respective sub-image identifiers, in parallel on independent channels, from the nodes via respective uplinks, and (2) retransmit the sub-images to the and sub-image identifiers to a remote location via a downlink; and

    a control station at the remote location, the control station being coupled to the relay by the downlink, the downlink being used to communicate the sub-images and sub-image identifiers from the relay to the control station, the control station being configured and operative to (1) receive the sub-images for the captured image along with the sub-image identifiers from the relay via the downlink, (2) re-create the captured image by combining the received sub-images according to the sub-image identifiers, and (3) utilize the re-created image in a monitoring or control operation of the central control station.
