A proposal for gps-less location detection using a reference direction information sharing method with co-operation of mobile terminals

摘要

It is our great pleasure to welcome you to the 1st ACM International Workshop on Mobile Entity Localization and Tracking in GPS-less Environments -- MELT'08. 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 industrial 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. >The call for papers attracted 38 submissions from Asia, Canada, Europe, and the United States. The program committee accepted 14 papers for oral presentations and 9 papers for poster presentations. The workshop consists of four technical sessions and three poster sessions, with topics covering areas of optimization and signal processing techniques, novel radio signal strength based methods, as well as systems and applications in MELT.
