Dynamic Voltage Scaling For Priority-Driven Scheduled Distributed Real-Time Systems, Chenxing Wang
Dynamic Voltage Scaling For Priority-Driven Scheduled Distributed Real-Time Systems, Chenxing Wang
University of Kentucky Doctoral Dissertations
Energy consumption is increasingly affecting battery life and cooling for real- time systems. Dynamic Voltage and frequency Scaling (DVS) has been shown to substantially reduce the energy consumption of uniprocessor real-time systems. It is worthwhile to extend the efficient DVS scheduling algorithms to distributed system with dependent tasks. The dissertation describes how to extend several effective uniprocessor DVS schedul- ing algorithms to distributed system with dependent task set. Task assignment and deadline assignment heuristics are proposed and compared with existing heuristics concerning energy-conserving performance. An admission test and a deadline com- putation algorithm are presented in the dissertation for dynamic …
