Abstract

A method for a first node in a wireless data network to estimate its spatial position. The first node receives information including: an identifier of a second node, the distances between various combinations of nodes, including a third, fourth, and fifth node. The first node generates an estimate of its spatial distance to the second node, based on the content of a four-simplex that is defined by the distances between the various combinations of nodes. The first node then generates an estimate of the spatial distance between the first node and an anchor node, based on estimates of the spatial distances between the first and second node and between the second and anchor node. The first node then generates an estimate of its spatial position, based on the estimate of the spatial distance between the first node and the anchor node and the spatial position of the anchor node.
