System and method for sensor tasking
First Claim
1. A system for sensor tasking comprising:
- a plurality of sensors operable to perform one or more tasks;
a processor operable to;
receive a mission, wherein the mission comprises one or more tasks to be performed by one or more of the plurality of sensors;
receive one or more environmental conditions associated with the mission;
generate a fuzzy cognitive map, wherein the fuzzy cognitive map comprises a plurality of nodes and weighted links between the nodes, the weighted links indicating causal relationships between the nodes, wherein a first weighted link of the weighted links that indicates a positive causal relationship between a first node and a second node of the first weighted link that indicates that if a value associated with one node of the first and second nodes increases then a value associated with the other node of the first and second nodes also increases, and wherein a second weighted link of the weighted links that indicates a negative causal relationship between a third node and a fourth node of the second weighted link indicates that if a value associated with one node of the third and fourth nodes increases then a value associated with the other node of the third and fourth nodes decreases, wherein the first node of the nodes includes an input node that includes a static value and the third node of the nodes includes a concept node that includes a dynamic value until the fuzzy cognitive map stabilizes, and wherein one or more of the plurality of nodes are associated with one or more of the environmental conditions;
select one or more of the plurality of sensors to perform each of the one or more tasks, the selection based at least on a state of the fuzzy cognitive map; and
schedule each of the one or more tasks to be performed by the respective selected one or more sensors.

Abstract
A system for sensor tasking includes a plurality of sensors operable to perform one or more tasks and a processor. The processor may receive a mission, wherein the mission comprises one or more tasks to be performed by one or more of the plurality of sensors. The processor may also receive one or more environmental conditions associated with the mission and generate a fuzzy cognitive map. The fuzzy cognitive map includes a plurality of nodes and weighted links, wherein one or more of the plurality of nodes are associated with one or more of the environmental conditions. The processor may be further operable to select one or more of the plurality of sensors to perform each of the one or more tasks based at least on a state of the fuzzy cognitive map and schedule each of the one or more tasks to be performed by the respective selected one or more sensors.
