Abstract

A system for detecting the occurrence of anomalies, includes a plurality of spaced apart nodes, with each node having adjacent nodes, each of the nodes having one or more sensors associated with the node and capable of detecting anomalies, and each of the nodes having a controller connected to the sensors associated with the node. The system also includes communication links between adjacent nodes, whereby the nodes form a network. Each controller is programmed to query its adjacent nodes to assess the status of the adjacent nodes and the communication links.

Claims

1. A system for detecting the occurrence of anomalies comprising:

a plurality of spaced apart nodes, with each node having adjacent nodes, each of the nodes having one or more sensors associated with the node and capable of detecting anomalies, and each of the nodes having a controller connected to the sensors associated with the node; and

communication links between adjacent nodes, whereby the nodes form a network;

wherein each controller is programmed to query its adjacent nodes to assess the status of the adjacent nodes and the communication links.

2. The system of claim 1 wherein each controller is programmed to transmit data over the links, and, upon a finding in response to a query of an adjacent node, that the adjacent node or the communication link to the adjacent node is inoperable, the controller is programmed to transmit data over a link to a different node.

3. The system of claim 1 in which each controller has memory storage, and each controller transmits data to an adjacent node, wherein the controller of the adjacent node stores the transmitted data in the memory of the adjacent node.

5. The system of claim 1 in which each controller is programmed to send commands to an adjacent node upon the detection of predetermined anomalies by its associated sensors.

6. The system of claim 1 in which each controller, when an anomaly is detected, is programmed to query its adjacent nodes to assess detection by the adjacent nodes, and upon corroboration of the anomaly by an adjacent node, the controller is programmed to transmit a signal indicative of the detection of the anomaly.

7. The system of claim 1 in which each controller, when an anomaly is detected, is programmed to collaborate with the controller of an adjacent node use information from the controller of the adjacent node in assessing a response to the anomaly.

8. The system of claim 1 in which at least one of the associated sensors of a node is configured to sense a condition related to a security threat, and at least one of the sensors of the node is configured to sense a non-security threatening condition.

10. The system of claim 1 in which each controller is programmed to determine a point of origin of a detected anomaly.

11. The system of claim 1 in which each controller is programmed to change its operation upon the occurrence of any one or more event in the group consisting of the detection of an anomaly, the destruction of a communication link to an adjacent node, a loss of power from a primary source of power, a loss of controller capability, a decrease in capability of a processor, a decrease in the capability of memory storage, and a command from another node.

12. The system of claim 1 in which each controller is programmed to deploy sensors outwardly from the node in response to the detection of an anomaly.
