Recently, there has been much focus on \textit{mobile} sensor networks, and we have even seen the development of small-profile sensing devices that are able to control their own movement.  Although it has been shown that mobility alleviates several issues relating to sensor network coverage and connectivity, many challenges remain.  Among these, the need for position estimation is perhaps the most important.  Not only is localization required to understand sensor data in a spatial context, but also for navigation, a key feature of mobile sensors.  In this paper, we present a survey on localization methods for mobile wireless sensor networks.  We provide taxonomies for mobile wireless sensors and localization, including common architectures, measurement techniques, and localization algorithms.  We conclude with a description of real-world mobile sensor applications that require position estimation.</style></abstract></record></records></xml>
