A system and method for managing a network of nodes that share sensor data is presented. In one embodiment, the system and method clusters groups of nodes into subnets. Nodes in a common subnet share sensor data with other nodes in the subnet at one rate, while nodes that are not in a common subnet share sensor data at a second substantially reduced rate. |

| Claim: |
1. A system for managing nodes on a network, comprising: a plurality of nodes, each node reporting a sensor data; a clustering unit that groups said plurality of nodes into a plurality of subnets; and wherein a first node of said plurality of nodes reports said sensor data to a second node of said plurality of nodes at a first rate if said first node and said second node are in a same subnet and at a second rate if said first node and said second node are in a different subnet, said second rate being substantially lower than said first rate. |
| Claim: |
2. The system of claim 1, wherein said first rate is between two and twenty times higher than said second rate. |
| Claim: |
3. The system of claim 1, wherein said clustering unit groups said plurality of nodes as a function of a distance between each of said nodes. |
| Claim: |
4. The system of claim 1, wherein said clustering unit groups said plurality of nodes as a function of an area of responsibility of each of said nodes. |
| Claim: |
5. The system of claim 1, wherein said clustering unit groups said plurality of nodes as a function of a connection time of a previous communications link between said one or more of said nodes, and as a function of an environmental impairment of a communications link between one or more of said nodes. |
| Claim: |
6. The system of claim 1, wherein said clustering unit periodically groups said plurality of nodes into a plurality of subnets. |
| Claim: |
7. The system of claim 1, wherein each of said plurality of nodes further comprises a tracker for fusing a plurality of said sensor data from said plurality of nodes into a target track using a data fusion algorithm, and further comprising, a tracker manager, said tracker monitoring said tracker and modifying said data fusion algorithm based at least in part upon a volume of said plurality of said sensor data at said tracker. |
| Claim: |
8. The system of claim 7, wherein said tracker manager modifies said data fusion algorithm based at least in part upon a criteria selected from the group consisting of a data accuracy requirement, a data priority requirement, and a mission objective requirement. |
| Claim: |
9. The system of claim 7, wherein said tracker manager instructs said tracker to drop at least one of said sensor data based upon said data fusion algorithm. |
| Claim: |
10. A method for sharing sensor data between a plurality of nodes on a network, comprising: grouping said plurality of nodes into a plurality of subnets; sharing said sensor data at a first rate between a plurality of nodes in a common subnet at a first rate; and sharing said sensor data at a second rate between a first node and a second node not in a common subnet; and wherein said first rate is greater than said second rate. |
| Claim: |
11. The method of claim 10, wherein said grouping is based at least in part upon a criteria selected from the group consisting of a common mission objective, a communications connectivity strength between nodes, a distance between nodes, a previous grouping between nodes, and an environmental impairment to a communications link between nodes. |
| Claim: |
12. The method of claim 10, further comprising: fusing a plurality of said sensor data from said plurality of nodes into a target track using a data fusion algorithm. |
| Claim: |
13. The method of claim 12, further comprising: modifying said data fusion algorithm based upon a volume measurement of said sensor data and a data fusion processing capability of a tracker. |
| Claim: |
14. The method of claim 13, further comprising: discarding a sensor data based at least in part upon said volume measurement. |
| Claim: |
15. The method of claim 13, further comprising: performing said step of grouping said plurality of nodes into a plurality of subnets at least in part upon one of said volume measurement of said sensor data and said data fusion processing capability of said tracker. |
| Claim: |
16. The method of claim 10, further comprising: discarding a sensor data based at least in part upon a mission objective. |
| Claim: |
17. The method of claim 10, further comprising: receiving an information from a node, said information selected from the group consisting of a modified mission objective, a change in communications connectivity strength between nodes, a change in distance between nodes, and an environmental impairment to a communications link between nodes; and performing said step of grouping said plurality of nodes into a plurality of subnets at least in part upon said information. |
| Claim: |
18. The method of claim 10, wherein said wherein said first rate is between two and twenty times faster than said second rate. |
| Claim: |
19. The method of claim 10, wherein each node in a common subnet shares a sensor data with each of said nodes in said common subset. |
| Claim: |
20. The method of claim 10, wherein a single node from a first subnet shares a sensor data with a plurality of nodes in a second subset. |
