This paper present a novel distributed 'virtual localization' method for mesh networks, such as sensor meshes, which do not depend on radio ranging or the existence of anchor nodes. Authors show in simulation that it can be used for establishing efficient and reliable location-based routing information. Miniaturized sensors which measure temperature, pressure, humidity and various chemical concentrations have become simple to mass-produce in recent years. The data processing power required to compress and analyse the measurements has become very cheap. Data however must still be collected and brought back for analysis.
