Wireless sensor network localization is an important area that attracted significant research interest. Hence, localization schemes for wireless sensor, although, mobility would appear to make localization more difficult. In this paper, the authors present a new method by which a sensor node can determine its location by listening to wireless transmissions from three or more fixed beacon nodes and argue that it can exploit mobility to improve the accuracy and precision of localization. Their approach does not require additional hardware on the nodes and works even when the movement of seeds and nodes is uncontrollable.
