The energy consumption of Cloud computing continues to be an area of significant concern as data center growth continues to increase. This paper reports on an energy efficient interoperable Cloud architecture realized as a Cloud toolbox that focuses on reducing the energy consumption of Cloud applications holistically across all deployments models. The architecture supports energy efficiency at service...
With the rapid growing number of Cloud applications, demands for large-scale data centers have raised to historical high. Cloud data centers allow dynamic and flexible resource provisioning to accommodate time varying computational demands. Recent studies have proposed several allocation policies based mainly on power consumption of servers. Host temperature, however, is rarely considered as a monitoring...
The main usage of cellular networks has changed from voice to data traffic, mostly requested by static users. In this paper, we analyze how a cellular network should be designed to provide such wireless broadband access with maximal energy efficiency (EE). Using stochastic geometry and a detailed power consumption model, we optimize the density of access points (APs), number of antennas and users...
3D-Stacked IC (3D-SIC) based on Through-Silicon-Vias (TSV) is an emerging technology that enables heterogeneous integration and high bandwidth low latency interconnection. In this paper we propose a 3D novel cache architecture that leverages a wide TSV-based data link distributed on the entire memory array to support two orthogonal interfaces: (i) a vertical one, with a large data width, and, (ii)...
With rapid increasing demand of cloud computing technology, energy efficiency has become highly important in cloud computing infrastructures. Cloud computing concept offers low cost and high level of availability. However, it still has some challenging problems, such as resource management and power consumption. In this concept, reducing energy consumption and maximize resource utilization, became...
Several approaches to reduce the power consumption of data enters have been described in the literature, most of which aim to improve energy efficiency by trading off performance for reducing power consumption. However, these approaches do not always provide means for administrators and users to specify how they want to explore such trade-offs. This work provides techniques for assigning jobs to distributed...
Digital revolution led to shift from the industrial age to ICT age. Cloud computing is one of the important innovation of the digital revolution. It is a new paradigm for hosting and delivering services using standard protocols of the Internet. It also provides the capability to utilize scalable, distributed computing environments within the confines of Internet with minimal management effort while...
In wireless ad-hoc network, all nodes work with the predefined limited battery power. It is difficult to select the path from source to destination considering both the parameters i.e. Less energy consumption and shortest path at the same time. This paper proposes a novel strategy that approach tries to account for energy efficient path with the minimum number of hops using a priority to check between...
This paper focuses on techniques or actions that the network operator should consider for the mobile network's evolution towards 5G from a sustainability point of view. To this end, the energy consumption of the Radio Access Network (RAN) is assessed when considering different load conditions (obtained by means of actual daily traffic profiles extracted from the live network) and different yearly...
In cooperative spectrum sensing, clustering of the sensor nodes is vastly employed in order to reduce overall energy expenditure due to reporting while preserving high detection performance. Cluster formation is especially difficult for mobile networks since the clusters immediately become invalid. In the mobile scenario, the cluster forming algorithm should take into account the total energy expenditure,...
Mathematical modeling for energy consumption of MANETs considering the impact of different layers in the protocol stack in addition to that of different network parameters remains unexplored till now even though such modeling is considered as the fastest and the most cost-effective tool for evaluating the performance of a network. Therefore, in this paper, we attempt to develop a mathematical model...
One of the issues in virtual machine consolidation (VMC) in cloud data centers is categorizing different workloads to classify the state of physical servers. In this paper, we propose a new scheme of host's load categorization in energy-performance VMC framework to reduce energy consumption while meeting the quality of service (QoS) requirement. Specifically the under loaded hosts are classified into...
Efficient energy use has become a critical issue for designing and managing of cloud data centers. Virtualization is a key technology for reducing energy cost and improving resource utilization in data centers. One of the challenges faced by virtualized data centers is to decide how to pack VMs on the least number of physical machines. This paper presents a VM management framework which is based on...
Reducing energy consumption has become a key issue for data centres, not only because of economical benefits but also for environmental and marketing reasons. Many approaches tackle this problem from the point of view of different hardware components, such as CPUs, storage and network interface cards (NIC). To this date, few works focused on the energy consumption of network transfers at the software...
Although cloud computing has been transformational to the IT industry, it is built on large data centres that often consume massive amounts of electrical power. Efforts have been made to reduce the energy clouds consume, with certain data centres now approaching a Power Usage Effectiveness (PUE) factor of 1.08. While this is an incredible mark, it also means that the IT infrastructure accounts for...
Energy consumption and total cost of ownership are daunting challenges for Datacenters, because they scale disproportionately with performance. Datacenters running financial analytics may incur extremely high operational costs in order to meet performance and latency requirements of their hosted applications. Recently, ARM-based microservers have emerged as a viable alternative to high-end servers,...
Dynamic churn in overlays is an obvious barrier to gathering collective availability constantly. Despite, a single index was mainly concerned, such as session time or node degree to select most-capable peers in previous works. In this paper, we propose a new utility function in which three metrics, deciding a quality of data dissemination services, are incorporated while considering energy consumption...
The emerging Network Function Virtualization paradigm (NFV) is a disruptive change that creates new business opportunities for vendors and carriers. By exploiting virtualization technologies, it allows the dynamic creation of logically isolated infrastructures over abstracted physical networks. To be able to offer Virtualized Services efficiently, service providers need a new class of Management systems...
Given the rapid progress in wireless devices and the serious demands of higher communication rate, future solutions for wireless networks have to deal with these needs. Proposed solutions must take into account the limited spectrum resource while keeping the energy efficiency. So, a typical processing will realize a balanced trade off: max-throughput/minenergy consumption. In this paper, our contribution...
Most of the on-demand routing protocols in WSNs are designed with the aim to find the best path based on a single routing metric such as minimum hop count, so that the End-to-End (ETE) delay can be minimized. In these protocols, the probability to select the same sensor node(s) all the time is high, resulting in overloaded nodes and increased energy consumption per node. Furthermore, in these protocols,...
