Message from the SIUMI Chairs
2005
e would like to welcome you all to SIUMI 2005, the Workshop on Services and Infrastructure for the Ubiquitous and Mobile Internet, held in conjunction with the 25th International Conference on Distributed Computing Systems. Advances in mobile and wireless communication are enlarging and enhancing the services provided by the Internet infrastructure towards any time, any place and any device features. Ubiquitous services impose new requirements to the entire infrastructure, from the system to the middleware and the applications that should be able to adapt traditional services to different mobile user terminals and profiles, and embed new functions and tools to support the new services and new requirements of the future scenario. The main motivation behind the establishing of the workshop is the idea that the new Internet service infrastructure can only succeed on the basis of a strict synergism between the heterogeneous variety of mobile wireless devices and the fixed network organization that should suit and follow the requirements and constraints imposed by the wireless and mobile counterpart. The specific limitations of mobile wireless devices, such as connectivity discontinuity and energy/resource shortages, connected with the new location- and context-sensitivity properties, are challenging issues that call for a reexamination on the design of the middleware of both the fixed and the mobile counterpart. In response to the Call for Papers, 30 papers from 11 different countries had been submitted. Based on three review reports per paper, they were classified as accepted, rejected, or discussed. For the last category papers, the final decision has been reached by considering additional reviews. As a result, a total of 16 papers were selected for presentation at SIUMI 2005. Accepted papers reflect the interest in the vision of a mobile and ubiquitous Internet and most of the different active directions of investigation in that area that is rapidly enhancing its focuses, growing with new solutions, and acquiring a significant maturity. The main interests emerged are currently directed to identification and location management, context awareness and content adaptation, middleware supports, and service composition. The workshop could not be successful without the help of many organizations and individuals. First, we would like to thank the ICDCS Workshops Chair Philip McKinley, Michigan State University, for his support, advice, and organizational suggestions. Next, we wish to thank all the Program Committee members and the external reviewers for evaluating the submitted papers in a timely and professional manner. Last, but not least, we thank all the authors for their submissions. Finally, we would also like to thank the MIUR FIRB WEB-MINDS Project “Wide-scale Broad-band Middleware for Network Distributed Services” that supported the fruitful discussions and interactions that inspired the idea of organizing the SIUMI Workshop.
