Data Management in Mobile Distributed Real Time Database Systems: Reviews and Issues

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.
