Abstract
Advances in computer and telecommunication technologies have made mobile computing a reality. In mobile computing environment, users can perform on-line transaction processing independent of their physical location. In the last decade, this new kind of computing paradigm has gained great development and posed new challenges to the database community. In mobile database systems, new features such as mobility, disconnection and long-lived transactions make traditional transaction processing schemes no longer suited. To solve this problem, a novel mobile transaction model, O2PC-MT, is proposed in this paper. By combining Optimistic Concurrency Control and Two-Phase Commit, O2PC-MT provides a flexible and effective support for mobile transactions. In order to compare the performance of our model with that of other mobile transaction schemes, we developed a detailed simulation model. The experiment results show that O2PC-MT model outperforms the previously proposed mobile transaction models that utilize the locking mechanism for mobile transaction processing.
