"Distributed Gaussian particle filtering using likelihood consensus";

We propose a distributed implementation of the Gaussian particle
filter (GPF) for use in a wireless sensor network. Each sensor runs
a local GPF that computes a global state estimate. The updating of
the particle weights at each sensor uses the joint likelihood function, which is calculated in a distributed way, using only local communications, via the recently proposed likelihood consensus scheme. A significant reduction of the number of particles can be achieved by means of another consensus algorithm. The performance of the proposed distributed GPF is demonstrated for a target tracking problem.
