contextual information and can also access a descrip-
tion of the problem space. Context is used by adap-
tation management to identify needs or desired
changes in the flow control and sensor scheduling.
These needs and changes are disseminated together
with relevant context data to the sensor manage-
ment module and the interlevel adaptive logic.
Once the system has the relevant context data,
the interlevel logic can define the actions to be taken
to improve the process, both inter- and intralevel.
Context-based sensor management receives requests
for data, data features, and sensor time-space point-
ing from other components of the IF system. It is in
charge of managing the sensor sets to satisfy requests
as well as possible.
A sensor adaptive logic knows the relationship
between the configuration parameters and the
effect on the data captured by the sensor. The logic
knows how to change sensor parameterization
(capabilities/features of the sensor: frequency, res-
olution, type of information) to obtain the desired
effect. The reasoning process of the sensor adap-
tive logic is expected to be fairly simple. Referring
to the previous example, a radar sensor adap-
tation process could ask for better resolution of
target sizes or shapes in a certain region, which is
