Real-time transaction management in mobile computing systems
E. Kayan, Özgür Ulusoy · 2003
In order to respond to real-time data access requirements of the underlying applications, mobile computing systems need to be supported by real-time DBMSs. In this paper we discuss critical issues related to real-time transaction management in mobile computing systems. We identify some open research problems and suggest directions for future work on possible solution methods. We also present a mobile database system model that takes into account the timing requirements of applications supported by mobile computing systems. We provide a transaction execution model with two alternative execution strategies for mobile transactions and evaluate the performance of the system considering various mobile system characteristics.
