The next generation Advanced Metering Infrastructure (AMI), with the aid of two-way Smart Metering Network (SMN), is expected to support many advanced functions. In this work, we focus on the application of remote periodic energy consumption reporting, which is a fundamental and significant component of Demand Response and Load Management. In order to support this periodic application with satisfactory...
It is an important preparatory work that to evaluate the energy consumption of thermal power units in power industry, directly affecting the effectiveness of energy-saving emission reduction. According to the actual situation of thermal power plants, it set up an evaluation index system of energy consumption, proposing using entropy weight method and AHP method to combine empowerment evaluation index...
Virtualization provides an excellent solution to resolve the portability, maintainability, development, and utilization problems in many system designs. In this paper, we are interested in energy-efficient designs for platform virtualization. In particular, we explore the computing resource mapping and the energy consumption relationship between virtual cores and physical cores when timing constraints...
In the past decade, energy-efficient real-time task scheduling has been widely explored in the form of various optimization problems. This paper considers energy-efficient real-time task synchronization protocols and the overhead of frequency switching in real systems design. We propose the concept of frequency locking to better manage the cost in frequency switching. To minimize the energy consumption...
Leakage power consumption contributes significantly to the overall power dissipation for systems that are manufactured in advanced deep sub-micron technology. Different from many previous results, this paper explores leakage-aware energy-efficient scheduling if leakage power consumption depends on temperature. We propose a pattern-based approach which divides a given time horizon into several time...
Dynamic voltage scaling (DVS) has been widely adopted to reduce the energy consumption resulting from the dynamic power of modern processors. However, while the leakage power resulting from the leakage current becomes significant, how to aggregate the idle time to turn processors to the sleep or dormant modes is crucial in reducing the overall energy consumption. Moreover, for systems with non-DVS...
As application complexity increases, modern embedded systems have adopted heterogeneous processing elements to enhance the computing capability or to reduce the power consumption. The heterogeneity has introduced challenges for energy efficiency in hardware and software implementations. This paper studies how to partition real-time tasks on a platform with heterogeneous processing elements (processors)...
In the past decade, energy-efficient real-time task scheduling has been widely explored in terms of various optimization problems. With a very different goal, this paper considers real-time task synchronization protocols with the minimization of energy consumption. We propose the concept of frequency locking and extend the priority ceiling protocol by locking the processor frequency in a restricted...
In the past decades, a number of research results have been reported for energy-efficient task scheduling over uniprocessor and multiprocessor environments. While researchers have started the exploring of slack reclaiming for tasks during run time, little work has been done for multiprocessor cases. This paper proposes a set of multiprocessor energy-efficient task scheduling algorithms with different...
