We consider distributed estimation of a time-dependent, random
state vector based on a generally nonlinear/non-Gaussian state-space
model. The current state is sensed by a serial sensor network without
a fusion center. We present an optimal distributed Bayesian estimation
algorithm that is sequential both in time and in space (i.e.,
across sensors) and requires only local communication between
neighboring sensors. For the linear/Gaussian case, the algorithm
reduces to a time-space-sequential, distributed form of the Kalman
filter. We also demonstrate the application of our state estimator to
a target tracking problem, using a dynamically defined "local sensor
chain" around the current target position.
