Editorial message: special track on mobile computing and applications

Riding on the success of the 2003 and 2004 Mobile Computing and Applications Track, we are pleased to present the 2005 Mobile Computing and Applications Track that features research papers drawn from a highly diversified spectrum of mobile computing. We have continued to receive a significant number of submissions this year. The papers collected in this track cover three different and yet complementary areas: mobile data management that realizes the applications of the mobile computing paradigm, under the system integration efforts provided by middleware to support mobile computing, that necessarily depends on the concrete mobile data communication research work. In particular, special attention was dedicated to draw upon research efforts and expertise from different areas of research, so as to promote better synergy and to bring forth not only core communication and sensor technologies that lay the research foundation, but also important research applications to realize the benefits of anywhere, any place and anytime pervasive and ubiquitous computing.
