Event-driven power management of portable systems

“…We compare the results obtained with our accurate SemiMarkov decision process model to the Continuous-time Markov decision process results [13]. CTMDP assumes that all state transitions are exponentially distributed, including the transitions between the active and LPidle or standby states that are better described by uniform distribution.…”

“…Thus the model becomes event-driven which is more appropriate for the event-driven environment found on most computers and embedded systems. In contrast with the Continuoustime Markov decision process (CTMDP) [13] where the times spent in a state are exponentially distributed,e Tbe Semi-Markov decision process allows the time between transitions to follow arbitrary probability distribution. The next section introduces the theoretical background of the SMDP.…”
