Nowdays, energy consumption as a critical issue in distributed computing systems with high performance has become so green computing tries to energy consumption, carbon footprint and CO2 emissions in high performance computing systems (HPCs) such as clusters, Grid and Cloud that a large number of parallel. Reducing energy consumption for high end computing can bring various benefits such as red...

CLOUD computing has introduced a major shift in the IT delivery model by offering computing resources for hosting applications as a utility. This helps businesses and organizations to access advanced IT facilities offered by cloud providers without the expensive up-front investments necessary to establish their own infrastructure. In this context, significant research efforts have already been ...

Cloud computing delivers services over the internet based on pay as you use financial model. Cloud providers publish service advertisements in different format (text, files, table and images) on the Internet. On the other hand, cloud consumers spend a lot of time and effort to find the appropriate cloud service using public search engines. Nowadays, cloud service discovery process considers as ...

Cloud computing is a pattern for delivering ubiquitous and on demand computing resources based on pay-as-you-use financial model. Typically, cloud providers advertise cloud service descriptions in various formats on the Internet. On the other hand, cloud consumers use available search engines (Google and Yahoo) to explore cloud service descriptions and find the adequate service. Unfortunately, ...

Cloud computing is becoming one of the major technological changes for business management in the last decade. From internal management to supply chain management, various services can be provided by cloud providers that locate somewhere in the world. However, despite its pervasive impact on business and economy, its understanding on the effect on economy is still in early stage. On the other h...

Cloud Computing is a paradigm in which tasks are assigned to a combination of computing resources, software and services accessed over a network following the pay-as–you-go financial model. It has been also described as on-demand computing. With the continuous increases of cloud service providers, it becomes crucial to develop a simulation tool to reflect the properties of such complex environm...

Cloud computing offers on-demand access to large-scale computing resources in a pay-as-you go manner. Market-based resource allocation mechanisms are gaining popularity among commercial cloud providers to deal with dynamically fluctuating resource demands. For example, the recently introduced Amazon EC2 spot instances allow users to bid for computing resources and thus control the cost vs. reli...

Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...

Recently, fog computing has been introducedto solve the challenges of cloud computing regarding Internet objects. One of the challenges in the field of fog computing is the scheduling of tasks requested by Internet objects. In this study, a review of articles related to task scheduling in fog computing has been done. At first, the research questions and goals will be introduced, an...

There are pressing economic as well as environmental arguments for the overhaul of the current outdated power grid, and its replacement with a Smart Grid that integrates new kinds of green power generating systems, monitors power use, and adapts consumption to match power costs and system load. This paper identifies some of the computing needs for building this smart grid, and examines the curr...
