Abstract

A node having a sensor and a computing device is provided for identifying a location of a source of a physical process. The node collects via the sensor a measurement of the physical process. The node repeatedly recalculates parameters until termination criterion is satisfied. The node receives parameters of a probability distribution and a gradient from other nodes. The node generates parameters based on the parameters and the gradients received from the other nodes. The node samples from a distribution of source locations based on the generated parameters. The node calculates a gradient derived from the sampled source locations, the generated parameters, and a joint probability of the sampled source locations and the measurement. The node sends to a subset of other nodes the generated parameters and the calculated gradient. When the termination criterion is satisfied, the generated parameters represent the probability distribution of the source location.
