Editorial message: special track on mobile computing and applications

Riding on the success of the previous Mobile Computing and Applications Track in 2003 to 2005, we are delighted to present the 2006 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 communications that forms the basis for higher level applications, inclusive of mobile data management as a support for practical mobile applications. 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 communications and modeling that support data management policies to lay the foundation for application development, but also important research applications to realize the benefits of anywhere, any place and anytime pervasive and ubiquitous computing.
