Location-awareness is a key component for achieving context-awareness. Recent years have witnessed an increasing trend of location-based services and applications. In most cases, however, location information is limited by the accessibility to GPS, which is unavailable for indoor or underground facilities and unreliable in urban environments. Much research has been done, in both the sensor network community and the ubiquitous computing community, to provide techniques for localization and tracking in GPS-less environments. Novel applications based on ad-hoc localization and real-time tracking of mobile entities are growing as a result of these technologies. It is time to bring leaders from both the academic and industry research communities to discuss challenging and open problems, to evaluate pros and cons of various approaches, to bridge the gap between theory and applications, and to envision new research opportunities in MELT.

After the first successful workshop on this topic (MELT '08), this workshop will continue to provide a forum for the state-of-the-art technologies in mobile localization and tracking and novel applications of location-based services. Both theoretical research driven by applications and system implementation with theoretical foundations are especially encouraged for this interactive and interdisciplinary workshop. The one-day workshop will be held at Ubicomp 2009, and will have a combination of invited talks, technical presentations and discussions.

There are still a limited number of workshop proceedings left, please contact melt09@lbssig.org for details.
