This process is known as belief propagation. , 2005), based on the Bayesian filters, the sensor network localization problem is formulated as an inference problem on a graphical model and a variant of belief propagation (BP) techniques, the so-called nonparametric belief propagation (NBP) algorithm, is applied to obtain an approximate solution to the sensor locations. The NBP idea is implemented as an iterative local message exchange algorithm, in each step of which each sensor node quantifies its “belief” about its location estimate, sends this belief information to its neighbours, receives relevant messages from them, and then iteratively updates its belief using Bayes’ formula.

V has only d neighbours, in R 2 v has a set of neighbours located on a line, or in R3 v has a set of neighbours located on a plane, which leads to the possibility of the neighbours forming a mirror through which v can be reflected. In discontinuous flex ambiguities in R d (d ∈ {2,3}), the removal of an edge or a set of edges allows the remaining part of the graph to be flexed to a different realization (which cannot be obtained from the original realization by translation, rotation or reflection) such that the removed edge can be reinserted with the same length.
