- public class Kalman
- extends java.lang.Object
Class that implements a modified Kalman filter.
The Kalman filter is a discrete predictive filter for signals with a
white noise
which are measured through a noisy procedure.
The default Kalman filter behavior has been modified to fit the network
model. It is used by the FetishLeaseRenewalManager to get an estimation
of the network delays to ensure Fetish lease renewal.
