Cloud computing allows business customers to scale up and down their resource usage based on needs. Many of the touted gains in the cloud model come from resource multiplexing through virtualization technology. In this paper, the authors present a system that uses virtualization technology to allocate data center resources dynamically based on application demands and ...

THE most widely proposed hand-held antenna for mobile satellite communication systems is the Quadrifilar Helix Antenna (QHA). The QHA is preferred to the crossed dipole and the patch for its small structure, insensitivity to ground or hand proximity effects, easily shaped radiation pattern, and wide circularly polarized beam. A method to reduce the axial length ...

Cloud computing provides the ability to utilize scalable, distributed computing environments via the Internet. Over the years, cloud computing has grown from being a promising business concept to a fast growing sector in IT organizations. It has emerged as a promising hosting platform that allows an intelligent usage of a collection of applications, information and ...

In this paper, the authors propose Shortest Best Path Tree-based Decentralization Mechanism (SBPTDM) which reduces the bandwidth consumption by utilizing partial paths. Energy consumption, reliability, security and computation cost are some of the constraints in Wireless Sensor Network (WSN) where security and privacy are the major constraints. To enhance Security in WSN, a mechanism called ...

In the contemporary world it is inevitable to develop front end applications without JavaScript. Many JavaScript programmers simply do code with less concern towards long term maintainability and optimized processing. Though JavaScript offers sundry methods of coding systems to reach the same end, there exist some practices which are pre-requisite to ensure that consequences will ...

As the people know PMOS and NMOS technology having many drawbacks. In this having speed is very slow and circuit complexity is increased and power dissipation is very high and low noise margin. So the designers are looking for new technology. CMOS was developed in 1963 by the researchers to overcome the drawbacks of PMOS ...

The Bit Error Ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. The proposed BER Tester (BERT) integrates fundamental baseband signal processing modules of a typical wireless communication system along with a realistic fading channel simulator and an accurate Gaussian noise generator ...

All the source of data collection and analysis of data provided in various formats (raw data from sensors, imagery, text-based from human reports, etc.) and distributed across heterogeneous data stores. The advance incensing technologies, the acquisition of new sensors that use of mobile devices result in the production of an overwhelming amount of sensed data ...

Cloud computing brought flexibility, scalability, and capital cost savings to the IT industry. In more companies turn to cloud solutions, securing cloud based service becomes increasingly important, because for many organizations, the final barrier to adopting cloud computing is sufficiently secure. The users rely on cloud storage as it is mainly because cloud storage is ...

Cloud computing has emerged as one of the most influential paradigms in the IT industry for last few years. A major feature of the cloud services is that users’ data are usually processed remotely in unknown machines. While enjoying the convenience brought by this new emerging technology; users’ fears of losing control of their own ...
