Abstract:
1. In a network comprising a node and at least one reference node, a method of determining an updated most likely position of the node in the network, the method comprising: identifying a first position probability space (PPS) associated with the node comprising a first centroid having a set of coordinates and a first se of a plurality of first vectors, each originating from the first centroid and defined by a magnitude and direction, wherein the magnitude of each first vector reflects an accuracy of a position of the node in the direction of the first vector; receiving, at the node, updated position measurement information from the reference node; and modifying, by the node and as a function of the received updated position measurement information, the first PPS to create an updated PPS (UPPS) that defines a space that encompasses positions where the node is most likely currently positioned in the network; wherein the UPPS comprises:
