SENSOR CALIBRATION USING DISTRIBUTED STOCHASTIC PARAMETER ESTIMATION

SENSOR CALIBRATION USING DISTRIBUTED STOCHASTIC PARAMETER ESTIMATION

Using a first sensor device in a network of sensor devices, sensor data is measured. A second sensor device comprising a trusted sensor device is selected from the network of sensor devices. A gain matrix is updated. Using the gain matrix, the sensor data, and a second parameter estimate received fr...

description Using a first sensor device in a network of sensor devices, sensor data is measured. A second sensor device comprising a trusted sensor device is selected from the network of sensor devices. A gain matrix is updated. Using the gain matrix, the sensor data, and a second parameter estimate received from the second sensor device, a first parameter estimate is updated. The first parameter estimate comprises an estimate of a parameter of a model representing the first sensor device. Using the gain matrix, an estimation error covariance matrix and a cross-variance matrix are updated. Using the updated first parameter estimate, second sensor data measured by the first sensor device is adjusted.
