In an inevitable changing world where our ecology is deteriorating and renewable resource is at its critical stage left us with only one option: “Go Green”. It postulates to design energy-efficient and economic internet equipment, albeit a trade-off between performances versus power saving. But it is the demand of time to adore power saving rather performance for the sustainable and green earth. As...
Emerging fog and mobile edge computing paradigms will create distributed pervasive virtualization environments, where computing, storage, and networking resources will be deployed at the network boundary in a capillary way. To effectively tackle the large dynamic fluctuations in workload engendered by user-centric services, effective energy management schemes must be in place to modulate power consumption...
With the growing popularity of high-performance computing devices such as tablets and smart-phones, and the growing trends of cloud-based services, forecasts indicate that the majority of Internet traffic will originate from inside of the buildings. Thus indoor network infrastructure needs to provide both better capacity and better coverage. Meanwhile, energy efficiency of the network becomes an additional...
Today's network architectures are not able to cope with the Future Internet requirements, as they are too inefficient, power hungry, and ossified on the TCP/IP paradigm. In order to promote a viable evolution towards new protocols and paradigms, modern network routers should become programmable to allow a flexible management of both traffic flows and power states. In this respect, Software Defined...
Energy efficiency has become one of the major design constraints for current and future cloud infrastructures. One way to conserve energy is to transition idle clusters, network elements and servers into low-powerstates. Therefore, Virtual Machine placement and dynamic re-configuration algorithms have beenrecently proposed for increasing the energy efficiency of virtualized infrastructures. However,...
The article focuses on the energy efficiency issue and the negative impact on the environment of Cloud computing based on data centers infrastructure. A modernization of Cloud architecture in terms of Green computing is proposed, using FPGA hardware accelerators and distributed peer-to-peer networks. Customer and FPGA as a Service (FAAS) interaction scenarios are discussed. A distributed peer-to-peer...
Datacenter federations are able to manage appropriately the green energy resources available in each datacenter (DC) thanks to their geographically distributed infrastructure, thus reducing energy expenditure. Scheduling algorithms can perform virtual machine migration, transferring a huge amount of raw data from one DC to another to minimize operational costs and ensuring a certain Quality of Experience...
Bandwidth-power tradeoff, as one of the key relations in the green radio research framework, has attracted numerous research attentions in the recent years, due to the refreshed spectrum policies and the popularity of enabling techniques for bandwidth adjustment (such as software defined radio). Previous literatures show some preliminary results on the bandwidth-power tradeoff for heterogeneous networks,...
To meet the global challenge of reducing greenhouse gas emissions and the explosive demand of wireless data traffic, green architecture design is becoming a critical issue for mobile network operators. Heterogeneous deployments of different cell types have been used to fulfill the challenges mentioned above. In this respect, a critical concern for operators is how to deploy small cells in a green...
Open Source Private Cloud (OSPC) is a full stack of private cloud solution based on Open Stack to help user enable and manage private cloud environment. Intel Intelligent Power Node Manager is a platform resident technology with power and thermal policies. In this paper, we introduce how to manage power in cloud computing effectively by integrating Intel Node Manager with OSPC and define this resolution...
Power resources on the mobile device are always valuable, meanwhile there are 4.6 billion mobile-phone subscribers worldwide. The total amount of energy consumed and the carbon footprint on those mobile devices is considerable which implies developing tools for green applications to become ever more critical. However, there is currently no effective way for application developers to know the power...
In this paper, we propose an energy saving solution for mobile systems based upon dynamic cell configuration for different scenarios. To characterize the optimal energy savings of base stations, we propose an active cell rotating scheme to control the number of active cells with regard to different work patterns switching among three states (active, receive and sleep). A recovery mechanism is enabled...
Cloud computing data centers are becoming increasingly popular for the provisioning of computing resources. The cost and operating expenses of data centers have skyrocketed with the increase in computing capacity. Several governmental, industrial, and academic surveys indicate that the energy utilized by computing and communication units within a data center contributes to a considerable slice of...
There is a growing tension within large organisations such as universities between the desire to perform vast amounts of computational processing and the desire to reduce power consumption by switching off computers. This situation will only worsen as computational problems get larger and the desire to save energy escalates. Through careful management of computing resources it is possible to maximise...
Energy consumption is an issue in general in information and communication technologies (ICT), but also cellular communications in particular. Base station sites are the main energy consumers in a mobile network. Their energy consumption significantly contributes to green house gas (CO2) emissions. Hence, service providers are looking for energy saving solutions in their existing and future deployments...
Global warming and climate changing is among the major challenges in the 21st century. In wireless communications, green architecture design is an urgent demand for operators, not only because of the social responsibilities but also their willingness to reduce the network construction and operating cost. Previous literatures tried to tackle deployment cost and energy efficiency in a separated manner...
