An important task of operating systems is to schedule shared resources fairly between several parties. Precise accounting of consumed resources is the key to that goal. However, most operating systems only use very basic accounting strategies. This thesis discusses methods for resource accounting and introduces a powerful, yet easy to use accounting model based on resource containers. The goal ...

Reducing the energy consumption of virtualized datacenters and the Cloud is very important in order to lower CO2 footprint and operational cost of a Cloud operator. However, there is a trade-off between energy consumption and perceived application performance. In order to save energy, Cloud operators want to consolidate as many Virtual Machines (VM) on the fewest possible physical servers, poss...

Due to the limitation of energy resources, energy efficiency is a key issue in wireless sensor networks (WSNs). Clustering is proved to be an important way to realize hierarchical topology control, which can improve the scalability and prolong the lifetime of wireless sensor networks. In this paper, an energy-driven unequal clustering protocol (EDUC) for heterogeneous wireless sensor networks i...

Cloud Computing is facing an increasing attention nowadays as it is present in many consumer appliances by advertising the illusion of infinite resources towards its customers. Nevertheless it raises severe issues with energy consumption: the higher levels of quality and availability require irrational energy expenditures. This paper proposes a Pliant system based virtual machine scheduling app...

Growing concern in the management of energy due to the increasing energy costs, has forced managers to optimize the amount of energy required to provide products and services. This research integrates an energy-based resource investment project-scheduling problem (RIP) under a multi-skilled structure of the resources. The proposed energy based multi skilled resource investment problem (EB-MSRIP...

Energy consumption in optical backbone networks is increasing due to two main reasons: (i) the exponential growth of bandwidth demands, and (ii) the increase in availability requirements in order to guarantee protection of the ultra high capacity optical channels provided by wavelength division multiplexing (WDM) networks. Although state of the art reliability mechanisms are very efficient in g...

Cloud computing is becoming an important opportunities for industry to provide a high degree of scalability and serviceability of computing resources. In order to integrate the system resource, utilize the resource flexibly, save the energy consumption, and meet the requirements of users in the cloud computing environment, one of the positive solutions is to apply the virtualization technology....

Our life is strongly linked with the usage of natural resources. Energy is a necessity in everyday life and is often generated using non-renewable natural resources which are finite. Energy consumption in manufacturing industry is increasing and the way it is consumed is not sustainable. There is great concern about minimizing consumption of energy in manufacturing industry to sustain the natur...

With the rapid development of our economy, the production is largely expanded and people’s living standard is greatly improved. However, energy consumption also brought us with many problems, which have been of wide concern by the whole world. To develop a low-carbon economy is an inevitable trend of solving the energy consumption problem for energy development. Moreover, the current energy uti...
