1. A system for managing nodes on a network, comprising:
- a plurality of nodes, each node reporting a sensor data to every other node of said plurality of nodes, and each node including a tracker for fusing a plurality of said sensor data from said plurality of nodes into a target track using a data fusion algorithm;
a tracker manager monitoring said trackers and modifying said data fusion algorithm to change between a faster processing mode and a higher quality processing mode based at least in part upon a volume of said plurality of said sensor data received by a tracker; and
a clustering unit that groups said plurality of nodes into a plurality of subnets;
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;
wherein each node of said plurality of nodes reports said sensor data to each of the other nodes in said plurality of nodes by sending a sensor message to the reported-to node at a first rate if the reporting node and the reported-to node are in a same subnet, and at a second rate if the reporting node and the reported-to node are in a different subnet, said second rate being substantially lower than said first rate; and
wherein said clustering unit groups said plurality of nodes as a function of a connection time during which one or more of said nodes has shared a direct connectivity communications link with another of said nodes, and as a function of an environmental impairment of the direct connectivity communications link between said one or more of said nodes and said another of said nodes.

Abstract
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.

9. A method for sharing sensor data between a plurality of nodes on a network, each node including a tracker for fusing a plurality of said sensor data from said plurality of nodes into a target track using a data fusion algorithm, the method comprising:
-
grouping a plurality of nodes into a plurality of subnets based at least in part upon a connection time during which a first node of said plurality of nodes has shared a direct connectivity communications link with another of said plurality of nodes, and upon an environmental impairment to the direct connectivity communications link between said first node and said another of said plurality of nodes; sharing a sensor data reported by said first node with every other node of said plurality of nodes by; (a) sending sensor messages at a first rate between said first node and each other node in a common subnet; and (b) sending sensor messages at a second rate between said first node and each other node of said plurality of nodes not in the common subnet, wherein said first rate is greater than said second rate; fusing said plurality of said sensor data from said plurality of nodes into said target track using said data fusion algorithm; modifying said data fusion algorithm to change between a faster processing mode and a higher quality processing mode based upon a volume measurement of said sensor data received by a tracker and a data fusion processing capability of said tracker; and modifying 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
