On Selecting Nodes to Improve Estimated Positions

— We consider node localization problems in ad hoc wireless networks in which two types of nodes are considered: nodes with self-locating capability like GPS and nodes with no self-locating capability. Our simple algorithm for improving the position accuracy consists of selecting and processing only the nodes that are likely to enhance the position estimation. We focus our approach on defining a hull of neighboring nodes as key of position accuracy enhancement.
