Summary:
In battery-driven real-time systems, there is requirement for adapting both energy consumption and Quality of Service (QoS) of tasks according to their importance. This paper proposes a power-aware resource allocation method to resolve a trade-off between the energy consumption and QoS according to their importance with guaranteeing the fairness. The proposed method accounts for energy consumption by devices as well as CPU with DVS and guarantees the system lifetime requirement. We formulate the resource allocation problem as a nonlinear optimization problem and propose a method to find the optimal allocation by an iterative method.
