This paper addresses the performance of geographical routing protocol in wireless networks, where only few nodes possess self- locating capability such as GPS. To be able to apply end-to-end geographical routing protocols, it is necessary every node know their position coordinates. We propose a method to infer such positioning information to any node, based only on connectivity and localization information obtained from the neighborhood. Three metrics are used to evaluate the performance of such a scheme: the density of useful nodes for geographical routing protocol, the reachability and the path length.8th IFIP/IEEE International conference on Mobile and Wireless CommunicationRed de Universidades con Carreras en Informática (RedUNCI)
