Resource allocation in dynamic real-time systems

Abstract

Dynamic real-time systems usually operate in an environment that is continuously changing.These changes in the environment cause workload of the system to vary during run time, and in effect causing system performance to fluctuate. In addition, certain Quality of Service (QoS) requirements are imposed on the real-time system and must be satisfied. Allocating system resource in this environment is challenging because a good and efficient allocation may become invalid when variations in workload cause Quality of Service violations.
