中文摘要：

针对移动数据库中的同步复制问题，将多agent技术和事务结果集引入到事务级同步复制中，提出了基于多agent的移动数据库事务级同步复制模型。该模型与现有模型相比，具有如下主要特点：a）提高了系统可扩充性；b）减少了移动设备及网络资源占用；c）设计了一系列针对恶劣网络环境的同步策略。实验结果验证了模型的优良性能和恶劣环境下的可用性。

英文摘要：

Aimed at the problem of synchronizing duplication in mobile database, this paper introduced the technology of multi-agent and transaction result set into synchronizing duplication of transaction level, and provided the model of synchroni- zing duplication in mobile database based on the technology of multi-agent. It compared with the existing models, this model had the following characteristics：a）improving the scalability of system;b）reducing the usage of mobile devices and network re- sources ; e） proposing a series of synchronization strategy aiming at the harsh network environment. Experimental results demon- strate the excellent performance of the model and the availability in harsh network environment.
