The energy consumption is a crucial issue for real-time systems,that's why optimizing it online, i.e. while the processor is running, has become essential and will be the goal of this thesis.This optimization is done by adapting the processor speed during the job execution.This thesis addresses several situations with different knowledge on past, active and future job characteristics.Firstly, we consider that all job characteristics are known (the offline case),and we propose a linear time algorithm to determine the speed schedule to execute n jobs on a single processor.Secondly, using Markov decision processes, we solve the case where past and active job characteristics are entirely known,and for future jobs only the probability distributi...
