The workshop on an Infrastructure for Mobile and Wireless Systems was held in Scottsdale, Arizona on October 15, 2001 and was funded by the National Science Foundation (NSF) and sponsored by the Telecommunications and Information Technology Institute of the College of Engineering at Florida International U- versity (FIU), to establish a common infrastructure for the discipline of mobile and wireless networking, and to serve its rapidly emerging mobile and wireless community of researchers and practitioners. The workshop provides a single, cohesive, and high-quality forum for disseminating research and experience in this emerging ?eld. Of signi?cance is the integration of many diverse com- nities. The areas of mobile and wireless networking combine the best of both worlds, namely academia and industry. The objective of the workshop is to - ?ne and establish a common infrastructure of the discipline and to develop a consensus-based document that will provide a foundation for implementation, standardization, and further research. Workshop Program Chairs Dr. Birgitta K] onig-Ries (Universit]at Karlsruhe), and Dr. Peter Scheuermann (Northwestern University) and Vice Program Chair Dr. S. A. M. Makki (Queensland University of Technology), assembled a truly - pressive program committee. Together with the program committee, they worked diligently to select papers and speakers that met the criteria of high quality and relevance to our various ?elds of interest. It takes time and e?ort to review a - per carefully, and every member of the program committee is to be commended for his/her contribution to the success of this workshop."
