IACM: An Admission Control Mechanism for Embedded Real-Time Database Systems
Xia Jia · Chinese Journal of Computers · 2004
Admission control mechanism, IACM, integrates the value of transactions with resource requirement. It preserves system resources by minimizing the likelihood of a transaction being accepted for execution but not being able to meet its deadline later. In IACM , one high priority transaction can be admitted only if its value is not littler than value summation of these transactions preempted by it when overload. The goal of IACM is to maximize system profit. In addition, IACM associates with the real time transaction model based on function alterative, so IACM suits for embedded real time database systems. At the later, the performance is compared through a stimulation system.
