Energy Guarantee Scheme for Real-time Systems with Energy Harvesting Constraints

Hussein El Ghor, Maryline Chetto

摘要节选:

...This work investigates the scheduling of periodic weekly hard real-time tasks under energy constraints. Based on this motivation, we proposed a real-time scheduling algorithm, namely energy guarantee dynamic voltage and frequency scaling (EG-DVFS), that utilizes the earliest deadline-harvesting (ED-H) scheduling algorithm combined with dynamic voltage and frequency scaling. ...Experimental results show that EG-DVFS can achieve capacity savings up of up to 33% when compared to ED-H.阅读全文
