Distributed virtual environments are gaining a lot of attention recently, due to the ever improving popularity of on the internet and social networking sites. As the variety of contingency users of a distributed virtual environment increases the critical issue is coming up, the issue describes as improving amount of work between several web servers how ...

Mobile cloud computing is process to compute the resources between multiple mobile devices. The mobile users demand a certain level of Quality of Services (QoSs) of their device. In this paper, the authors are Identify, Formulate, and address the problem of QoS. The bandwidth sifting alone is not sufficient for maintaining QoS-guaranteed because of verifying ...

Cloud computing is used to utilize the shared resources to a maximum possible extent. These resources are shared by more than one user at a time as per their need. This improves computing power for using various applications at various places with additional advantage of cost saving on storage space and electricity consumption. Virtualization is ...

Web service is working with the web with an object or component to achieve the communication between the distributed applications and between the different platforms through a series of protocols. Web service provides a set of standard types systems, rules, techniques and internet service-oriented applications for communication between the different platforms, different programming languages and ...

With Web technology, data on internet has become increasingly large and complex. No matter users or internet users needs all this data. Also the data which is available on web not all the time useful information or it is knowledgeable. Hence web data mining is necessary to fulfill this demand. Web data mining can extract ...

Multimedia information retrieval is very useful for any application in the daily work. Most of the applications consist of multimedia data that are images, text, audio and video. Multimedia information retrieval system is used to search an image. There are same meanings for different data which is also known as semantic gap. This problem is ...

Wireless Power Transfer (WPT) is the propagation of electrical energy from a power source to an electrical load without the use of interconnecting wires. It is becoming very popular in recent applications. Wireless transmission is useful in cases where interconnecting wires are difficult, hazardous, or non-existent. Wireless power transfer is becoming popular for induction heating, ...

Cognitive Radios (CRs) are the radios that are widely used in the wireless networks. It is a software based air interface network. Due to the air interface, the probability of attacks increases. In cognitive radio network, an attack can be defined as an activity that can cause interference to the primary users or licensed users. ...

To fulfil the increasing demand of compact antennas for various applications such as WLAN, satellite and radar the field of printed microstrip patch antennas have gained researcher’s attention. The difficulty in designing antenna challenges engineers when the size of the antenna reduces and the number of operating frequency band increases. A lot of work has ...

Cloud computing allows customers to expand resource based on the data used, many are multiplexed by virtualization technology. Here the system uses virtualization technique to allocate data used by the users depending on their usage, also asymmetric is also checked of a server. Overall performance of the system is improvised and energy is also saved. ...
