Section II provides an overview about mobile clouds and the analytical modeling for availability evaluation. The methodology adopted is presented in detail in Section III. Section IV presents the models developed to represent a mobile cloud system. A case study is described in Section V, with the results obtained through model analysis. Section VI concludes the paper, presenting also some possible future works. II. BACKGROUND

Abstract—Mobile cloud computing refers to abstraction of computational power to outside of the mobile device, processed in the “clouds”. This paper provides an availability and energy consumption study using hierarchical heterogeneous modeling. Different scenarios were analyzed considering wireless communication technologies, such as 3G and WiFi. The results shows that the 3G protocol causes a lower availability and is the greater responsible for the discharge of battery, but when is combined with WiFi protocol providing communication redundancy, we have the best results of availability and better results of uninterrupted operation time of battery.

In the last years, the tech industry has showed a special interest in cloud computing and mobile devices. Cloud computing enables the use of computing resources by means of providers that may be in any geographic location, accessible through de Internet, i.e., in the clouds [1]. In parallel with the advance of cloud computing, mobile phones have evolved from

Our goal is to provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on four themes: productivity and growth, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed job creation, resource productivity, cities of the future, and the impact of the Internet. MGI is led by McKinsey & Company directors Richard Dobbs and James Manyika. Yougang Chen, Michael Chui, Susan Lund, and Jaana Remes serve as MGI principals.

That’s because the clouds that interest IT executives today aren’t of the meteorological variety; they are computing clouds. Widespread interest and even unabashed excitement about cloud computing emanates from businesses, government agencies and other organizations seeking more dynamic, resilient and cost-effective IT systems than previous generations of technology allowed. While the term “cloud” may connote an ephemeral quality to the type of computing it describes, the benefits of cloud computing to customers are very tangible. IBM itself— as well as clients around the world—is adopting cloud computing in recognition of its potential to usher in a new era of responsiveness, effectiveness and efficiency in IT service delivery. “Cloud computing represents a key technology in delivering new economics, rapid deployment...

Internet of Things

...by research, that all animals and plants communicate with each other and with ever advancing technologies, it has been possible for humans to communicate effectively with the modern machines as well. Which brings us to the question, can machines communicate with other machines? Can we envisage an environment in which objects, animals or people have communication channels which do not require human-to-human or human-to-computer interaction for interaction? The Internet of Things(IoT) helps create an environment in which machines can interact amongst themselves or with living beings (human, animals and plants), where each entity is provided with unique identifiers and the ability to transfer data over a network without any human-to-human or human-to-machine interaction (Wigmore, 2014). IoT is a generic term and all entities play an active role owing to their connection to the Internet. It provides access to information, media and services, through wired and wireless broadband connections. The IoT feeds from the connections set up between the Consumer, Business and Industrial Internet to help create new services leading to smart, efficient and more intelligent environment. The Internet of Things is not a single technology, rather it’s a conglomerate of different things and providing solution based on integration of information technology (Vermesan and Friess, 2013). Apart from being used in new applications, the IoT also generates large amounts of data which can be...

Future Where Money Is Only Electronic

...activities. From history, computer forms have evolved from time to time. From a poor performance computer that filled the entire room to a bulky computer that sat on the entire table, to now being small compact laptop, tablet, and mobile that fit in a tiny pocket. In today’s environment, credit card is a great example how money went partially electronically. The drawback of using a credit card is that of the credit card receiver (eg. credit card is unusable if there is no device to accept). The future will need computers to miniaturize into a small fingertip size, which enables money to seamlessly transfer from one party to another. Credit card receivers will be small enough to fit into a wallet, just like a credit card, and have the functionalities to control over all financial needs just like using cash/check today. Power: In order to keep mobility and minimal form factor, one needs to consider its on power. In the future, power consumption on certain devices will be low, while power generation will be high in order to ensure usability throughout the day. Tiny solar cell, or kinetic power generation are enough to supply power to the entire device. Vibration and movement from regular activities will supply low energy consumption devices. Idle devices will consume nearly zero power, which could help extend usage for years without recharge. Small but powerful battery...

I understand that failure to attribute material which is obtained from another source may be considered as plagiarism. (Signature of student) Abstract Cloud computing is a breakthrough innovation in information technology industry. It brings new efficiencies and advantages to business. There is much hype about environmental impacts of cloud computing on green issues. Some favour of cloud computing as solution to green issues while others blame cloud computing as burden to environmental problems. Cloud computing, nevertheless, like other technology, is neutral. It can be either cause or solution to environmental issues. There is growing pressure on cloud computing industry to reduce the environmental impacts of their data centres. The current trend focuses on developing green cloud computing. However, the evaluation of solutions to green cloud computing bases on certain standards, metrics and benchmarks, which assess only parts of the environmental issues with cloud computing. This report will concentrate on green issues with cloud computing. Significant positive and negative impacts of cloud computing on the environment issues will be investigated. Next, a classification of green issues with cloud computing also is...

Internet of Things

...| Internet of Things | 2014| Pragya Vaishwanar | Aricent Marketing Research Report | Summary It’s fair to say that more people have heard of the “internet of things” than have experienced it. More objects are becoming embedded with sensors and gaining the ability to communicate. The resulting information networks promise to create new business models, improve business processes, and reduce costs and risks. There is breathless press coverage of the phenomenon—always patiently re-explained by tech pundits as the trend by which all of one’s most mundane possessions will become internet-connected. These are invariably coupled with estimates that the internet of things will be a multi-trillion dollar business. 2014 is really, finally the year that the “internet of things”—that effort to remotely control every object on earth —becomes visible in one’s everyday lives. In a sense the internet of things is already with us. For one thing, anyone with a smartphone has already joined the club. The average smartphone is brimming with sensors—an accelerometer, a compass, GPS, light, sound, altimeter. It’s the prototypical internet-connected listening station, equally adept at monitoring our health, the velocity of our car, the magnitude of earthquakes and countless other things that its creators never envisioned. Yet despite repeated declarations one of the most successful sellers of baubles that help make your home “smart,” Smart-things, has only shipped 10,000 or so units since...
