NETWORKED LOW-BANDWIDTH TERMINALS FOR TRANSMISSION OF IMAGERY
First Claim
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 thereamong, 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, (3) image-transmission circuitry by which a node transmits on a respective uplink a respective sub-image received from another node;
a relay configured and operative, with multiple channels, to (1) receive transmissions of respective sub-images, in parallel on independent channels, from the nodes via respective uplinks, and (2) retransmit the sub-images to the remote location via a downlink; and
a control station at the remote location, the control station being configured and operative to (1) receive the sub-images from the relay via the downlink, (2) re-create the captured image by combining the received sub-images, and (3) utilize the re-created image in a monitoring or control operation of the central control station.

Abstract
A system includes nodes deployable across an area and self-forming a mobile ad-hoc network. The nodes include (1) imaging circuitry for capturing an image of a local sub-area based on a triggering event, (2) image-transfer circuitry for partitioning a captured image into sub-images or image segments and transmitting them to other nodes, (3) image-transmission circuitry for transmitting a sub-image from another node on an uplink to a relay such as a satellite. The relay (1) receives transmissions of respective sub-images, in parallel on independent channels, from the nodes via respective uplinks, and (2) retransmits the sub-images to the remote location via a downlink. A central control station at the remote location (1) receives the sub-images from the relay via the downlink, (2) re-creates the captured image by combining the received sub-images, and (3) utilizes the re-created image in a monitoring or control operation of the central control station.

19. A node for use in a system, the system having a set of nodes deployable across an area, a relay, and a control station in communication with the nodes via the relay, the node comprising:
-
network interface circuitry configured and operative to enable the node to participate with other nodes to self-form a mobile ad-hoc network for communication thereamong; imaging circuitry by which the node captures an image of a respective local sub-area based on a triggering event; image-transfer circuitry by which the node partitions a captured image into a plurality of sub-images and transmits the sub-images to respective other nodes of the mobile ad-hoc network; and image-transmission circuitry by which the node transmits on a respective uplink to the relay a respective sub-image received from another node.
