移动数据库的并行数据分发控制技术研究

Research of Data Dissemination with Concurrency Control in Mobile Environment

移动计算环境中上下行通信链路资源有限,通信链路频繁断连。数据移动终端用户如何能在移动计算环境中高效的访问数据,保证数据的实时性是文章的研究重点。通过提出一种基于并发控制的数据广播技术,来保证移动数据终端对数据的访问效率、时效性等性能的要求。实验结果表明数据访问的效率、时效性得到了提高。

In mobile computing environment,the resources of downlink and uplink are limited.The link is disconnected frequently.The purpose of this research is that the method can make the mobile data terminals access data effectively and instantly.In this paper,concurrent control,data broadcast are researched.The experiment result shows that the algorithm is effective and robust.Using this method,the performance of the data access in mobile computing environment is enhanced significantly.
