This chapter presents a design method for multisensor track-to-track fusion estimators with nonuniform estimation rates, and the aforementioned two issues will be addressed. In the estimation system, a WSN with a group of sensors is deployed to monitor the outputs of a discrete-time stochastic dynamic process, and each sensor acts also as an estimator. At the first stage, each sensor generates local estimates with a nonuniform rate by using its own measurements, and it is assumed that the estimation rate switches between a fast one and a slow one according to a white Bernoulli random process, and each local estimation system is modeled as a discrete-time system with a stochastic parameter.
