关注能耗的嵌入式实时数据库服务质量管理

Power-aware QoS Management for Embedded Real-time Databases

提出了一种关注能耗的嵌入式实时数据库服务质量管理策略.该策略使用反馈控制方法来支持预设的能耗目标值,通过更新算法与数据有效期的动态调整以及接纳控制来实现系统中数据实时性和用户事务实时性的有效维护.实验结果表明,相比于基线策略,所提出的策略能在满足能耗约束的前提下达到更高的数据和事务质量.

In this paper,we present a QoS management scheme for embedded real-time databases that takes energy consumption into consideration.The scheme applies a feedback based control method to support the desired power consumption.It efficiently maintains transaction timeliness and data freshness by update algorithm selection,validity interval adaptation and admission control.The performance of the proposed scheme is studied through experiments.The results show that compared with the baseline scheme,the proposed scheme can satisfy the power consumption requirements while achieve better quality of both data and transactions.
