Proceedings of the 3rd ACM international workshop on Data engineering for wireless and mobile access

It is our great pleasure to welcome you all to the biennial ACM International Workshop on Data Engineering for Wireless and Mobile Access (MobiDE'03), held in conjunction with MobiCom 2003. This workshop brings together researchers in databases, networking, and mobile computing and provides opportunities for a full day of exciting discussions on the topic of data management in mobile environments. The workshop will serve as a forum for researchers and technologists to discuss the state-of-the-art, present their contributions, generate fresh ideas and set future directions in data management for mobile and wireless access.MobiDE'03 is the third of a series of workshops that aims to act as a bridge between the data management and the mobile computing communities. The first MobiDE workshop (MobiDE'99) took place in Seattle in August 1999, in conjunction with MobiCom 1999. The second MobiDE workshop (MobiDE'01) was held in conjunction with SIGMOD/PODS 2001 in Santa Barbara in May 2001.The workshop program has been put together with the aim of presenting new and controversial research ideas so as to foster interaction among researchers in the community. Our call for papers attracted 34 high-quality submissions making the selection very competitive. Most papers were reviewed by 4 members of the Program Committee, with only a few papers receiving 3 reviews. After a discussion phase on a few papers with conflicting reviews, 9 full papers were accepted. This represents a highly competitive acceptance ratio of 26.5%. In addition, we accepted 5 short papers that represented promising works in progress. The resulting program reflects both the depth and the breadth of the field with sessions covering pervasive computing, sensor networks, location queries, consistency/replication issues and mobile systems and prototypes. Thus, these proceedings provide an excellent point of reference on the increasingly important area of data engineering for mobile as well as wireless computing.A special part of MobiDE's mission has been to foster new collaborations, and expose new and young researchers to emerging research opportunities in mobile and wireless computing. In order to facilitate graduate student participation in the workshop, MobiDE'03 hopes to start a new tradition by awarding travel grants for graduate students and exceptional undergraduate students. Towards this we have been encouraged by both Maria Zemankova, Director of NSF's Information and Data Management Program, and Taieb Znati, NSF's Senior Program Director and ITR, CAREER Program Director. This year 14 students (13 graduate and 1 undergraduate) will receive travel awards based on their position statements, academic performance and advisors' recommendation letters.In addition to the student travel grant awards, another new event at MobiDE this year is the introduction of a best paper award, based on review ratings. This year, the paper "Consistency Mechanisms for a Distributed Lookup Service supporting Mobile Applications" co-authored by Christoph Lindemann and Oliver Waldhorst has won the best paper award and will be presented in the third technical session of the workshop.
