ABSTRACT
In energy-constrained settings, most real-time operating
systems take the approach of minimizing the energy
consumption while meeting all the task deadlines.
However, it is possible that the available energy budget is
not sufficient to meet all deadlines and some deadlines will
inevitably have to be missed. In this paper, we present a
framework through which the operating system can select
jobs for execution in order to achieve two alternative
performance objectives: 1) maximizing the number of
deadlines met , and 2) maximizing the total reward (utility)
of jobs that meet their deadlines during the operation. We
