摘　　要：在综合分析现有事务模型的基础上,提出了一种根据事务提交所处的网络环境和事务是否访问热点数据,自动选择子事务处理模型的基于权值的自适应移动事务处理模型——AMTMBW。实验证明,新的事务处理模型在移动事务的撤销率,移动事务的执行时间等方面与其他模型相比,其性能都有较大的提高。Mobile transaction model is one of the key technologies. Based on the analysis of the present transaction models, this paper proposed an adaptable mobile transaction model based on weight, which can itself choose sub-transaction model according to the transaction＇s network and whether the transaction visits the hot data. The results of experiment show that new model has better performance at mobile transaction redo ratio and executing time than other models.
