System and method for automated tracking of assets using location measurements and ad-hoc routing algorithms
First Claim
1. A method for tracking at least one asset using a multihopping communication network comprising a plurality of nodes, the method comprising:
- assigning at least one mobile node in the network to at least one asset;
assigning at least one stationary node in the network to at least one visual monitoring device;
tracking movement of the mobile node assigned to the asset in the network, wherein the tracking comprises;
measuring one or more location data and one or more ranging data of the at least one asset by one or more nodes operating in the multihopping communication network, andtracking movement of the mobile node based on the measured one or more location data and one or more ranging data; and
operating the visual monitoring device to capture image data of the asset based at least in part on the measured one or more location data and one or more ranging data.

Abstract
A system and method for automated visual tracking of assets (302), such as personnel or vehicles, using location measurements and ad-hoc routing algorithms employed in a wireless multihopping communication network (100). The system and method comprise a plurality of imaging devices (300) that are deployed about an area and provide image information to at least one workstation (304) that displays the images based on the image information. In particular, as an asset (302) moves, the workstation (304) switches from displaying an image of the asset (302) captured by an imaging device (300) away from which the asset (302) is moving to displaying an image of the asset (302) captured by an imaging device (300) toward which the asset (302) is moving.

10. A system for tracking at least one asset using a multihopping communication network comprising a plurality of nodes, the system comprising:
-
at least one mobile node to communicate in the network and assigned to at least one asset; and at least one stationary node to communicate in the network and assigned to at least one visual monitoring device, wherein the stationary node tracks movement of the mobile node assigned to the asset in the network based at least in part on one or more location data and one or more ranging data measured at one or more nodes operating in the multihopping communication network, and sends the one or more location data and one or more ranging data to the visual monitoring device based at least in part on which the visual monitoring device captures image data of the asset. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for tracking a visual image of at least one asset in a mobile ad hoc communication network, the method comprising:
-
displaying a first view captured by a first imaging device of the at least one asset at a monitoring station when the at least one asset is within imaging range of the first imaging device; detecting at the monitoring station that the at least one asset is moving from the imaging range of the first imaging device to an imaging range of a second imaging device wherein the detecting comprises measuring one or more location data and one or more ranging data of the at least one asset by one or more nodes operating within the mobile ad hoc communication network, and detecting at the monitoring station that the at least one asset is moving from the imaging range of the first imaging device to an imaging range of a second imaging device based on the measured one or more location data and one or more ranging data; and displaying at the monitoring station a second view captured by the second imaging device of the at least one asset. - View Dependent Claims (20, 21, 22)
