The energy consumption of Data Centers (DCs) is a very important figure for the telecommunications operators, not only in terms of cost, but also in terms of operational reliability. A relation between the energy consumption and the weather conditions would indicate that weather forecast models could be used for predicting energy consumption of DCs. A reliable forecast would result in a more ef...

In this study, a hybrid system has been modulate and simulated, this system is composed with three generators, two on renewable energy (solar and wind power) and one on combustible energy (diesel generator). This central distributes energy to a small village in southwest of Algeria named “Timiaouine”, this central has been sized using mathematic parameter and repartition of consumption for 24 h...

pisciculture, especially in countries which are unable to develop their marine resources, is a desired to provide part of their food and protein needs. this study aims at investigating welfare impacts of energy subsidy removal on fish producers in fars province. to achieve the objective, cross-sectional data obtained from fish producers of fars province in 2010 was used. cost, input demand and ...

In this paper we develop and analyze a wireless wave leader election protocol (WWLE) for wireless mobile ad hoc networks, with emphasis on the resulting energy consumption. Within the operating system of the EYES architecture we apply a power model to schedule tasks in order to minimize energy consumption. This model is applied to evaluate the protocol for di erent network topologies, taking in...

1. introduction the concept of sustainable travel and transport is embedded in the broader concept of sustainable development, which relates to maintaining or improving the quality of human life and variety of social opportunities within the natural constraints and limits of the global ecosystem. the organization for economic cooperation and development (2004) defines an environmentally sustain...

Checkpointing is a fault-tolerance mechanism commonly used in High Throughput Computing (HTC) environments to allow the execution of long-running computational tasks on compute resources subject to hardware and software failures and interruptions from resource owners. With increasing scrutiny of the energy consumption of IT infrastructures, it is important to understand the impact of checkpoint...

Cloud computing become more popular in every field of life nowadays. This happened only due to its amazing services that provide to clients in the form of everything-as-aservice(XaaS). Where at one side cloud computing is gaining popularity and another side its faces some issues i.e. security issue, total cost issue, energy consumption issue, performance issue, QoS issue, etc. In above all chal...

Cloud computing is an important paradigm in Information Knowledge field. The main aim of Green Cloud computing is to reduce the energy consumed by physical resources in data center and save energy and also increases the performance of the system. There are several scheduling algorithms such as Adaptive Min-Min Scheduling Algorithm; Multilevel Feedback Queue Scheduling Algorithm etc. are utilize...

Traditionally, researchers have focused on security, complexity, and throughput metrics while designing security protocols for wired networks. Deployment of these security protocols in battery-powered mobile devices has elevated energy consumption into an important design metric. In this paper we study the energy consumption characteristics of secure session negotiation protocols used by IPSec ...
