【摘要】 近年来,无线技术的发展促进了移动计算的研究,但是多数移动数据库系统使用传统的客户机/服务器模式或单代理模式处理移动查询,进而产生了数据大量迁移的问题。文章提出了一种基于多移动代理技术的移动数据库查询处理模型,旨在减少处理过程中的数据迁移量,提高移动环境下查询分布式异构数据库的性能。更多还原

【Abstract】 For the time being, the progress of wireless network technology boosts the mobile compute study, but most of the mobile database system use the traditional client / server model or single-agent model to deal with mobile query, which brings the enormous data movement problem. The paper proposes a new mobile database query transaction model which uses multi mobile agent technology to reduce data traffics in the process and enhance the performance of query transactions of a distributed heterogeneous database in mobile environment.更多还原
