How to reduce energy consumption under the restraints of satisfying customer service level by effective resource allocation and scheduling has become a key issue in cloud computing. In this paper, we propose a new resources-allocation and scheduling architecture for energy consumption optimization. Based on this architecture, a new energy consumption optimization model is designed to meet the real-time...
Recently, technologies on reducing energy consumption of data centers have drawn considerable attentions. One constructive way is to improve energy efficiency of servers. Aiming at this goal, we propose a new energy-aware optimization model based on the combination of data placement and task scheduling in this paper. The main contributions are: (1)The impact of servers' performance on energy consumption...
With the cloud paradigm being applied broadly, how to make an efficient scheme of resource placement regarding to the energy cost has become a prerequisite problem to be solved. But nearly all of existing resource placement approaches always ignore the energy use caused by virtual machine (VM) dynamical migration. In this paper, we established the energy consumption model in cloud computing environment,...
For the problem that the energy efficiency of the cloud computing data center is low, from the point of view of the energy efficiency of the servers, we propose a new energy-efficient multi-task scheduling model based on Google's massive data processing framework. To solve this model, we design a practical encoding and decoding method for the individuals, and construct an overall energy efficiency...
Considering the mount of high temperature steam consumed in the evaporation process is large, which is much higher than designed value, an optimization model is established to minimize steam consumption per ton of evaporated water. It focuses on operation optimization of evaporation process and takes into account a wide range of operating conditions and system configurations. And a new vortex motion...
This paper proposes a reliable access scheme in the Medium Access Control (MAC) layer of Wireless Sensor Networks (WSN) called Explicit Reservation with Coordinated Sleeping (ERCS). Nowadays, most access mechanisms proposed for WSN are costly and difficult to build an entire network. However, the research of ERCS is significant since it is the one based on the widely used IEEE 802.11b which is already...
Wireless sensor networks have been widely used in many important areas. Medium access control (MAC) protocols have a significant effect on the function and performance of sensor networks. Though the TDMA-based MAC protocols are inherently collision free and can rule out idle listening since nodes know when to transmit, it is difficult to change the frame size and time slot assignment due to network...
