摘要：Recent advances in wireless communication networks and portable computers have led to the emergence of a new research area called mobile computing systems. An important part of the research conducted in mobile computing systems has been done on mobile data management. What make the mobile data management different from the conventional data management are the mobility of the users or the computers connected to the system, and the resource constraints such as wireless bandwidth and battery life. As a result of such distinctive features of mobile systems, the data management techniques developed for conventional distributed database systems may not work well in a mobile environment. Research contributions are required in a variety of areas, such as distribution of data on mobile and/or non-mobile computers, processing of queries and transactions submitted by mobile users, maintaining the consistency of data cached on mobile computers, and so on. Another important issue that needs to be considered in mobile data management is the requirement of processing queries and transactions within certain time limits in order to maintain the temporal validity of the data accessed by those queries and transactions. Our basic objective in this project is a thorough investigation of the issues to develop various types of methods for mobile data management in response to the requirements mentioned.
