In mobile distributed databases, the communications between sites only provide weakconnectivity. To improve the efficiency of transaction processing in mobile computers, lazyreplication is used extensively. But this approach either don't guarantee serializability andconsistency as needed by applications or impose restrictions on placement of data and which data objects can be updated. The shortcomings make it difficult for lazy replication to be adaptive to the dynamic changes of network connection and configuration in mobile environments. In the paper, we propose a probability-based approach, which guarantees serializability and consistency. We adopt the quality of service specification and achieve transaction consistency dynamically through the collaboration between applicationsand systems. Probability-based approach is flexible and adaptive to mobile computingenvironments. The experimental results suggest that probability-based approach outperformordinary lazy replication.
