Optimization of Power Consumption in Low Power System using Hybrid System Model

In this paper, a new hybrid model for optimization of power consumption system the problem of optimization of power consumption is considered. The equation describing the power consumption is briefly discussed. Based on the fact that the power consumption is proportional to the square of voltage, a new voltage scheduling technique is proposed, which schedule both voltage and frequency. For this purpose, the task operation is modelled as a hybrid queueing network. Through the simulations, it is shown that the proposed algorithm performs better than the existing technique.
