Cloud computing has emerged as an effective solution in the computing world. When the cloud is used for large amounts of data storage, searching for any required data takes lots of time. A framework is required to distribute the work of searching and fetching from thousands of computers. The data in Hadoop Distributed File System is scattered and needs lots of time to retrieve. MapReduce function...
Virtualization technology enabled hosting of applications and services in an isolated and resource guaranteed virtual machines (VMs). Typically single physical machine (PM) runs multiple virtual machines and application resource demands are changing with time. To achieve this, dynamic resource provisioning of physical machine resources to VMs in virtualized data center is necessary. Data center requires...
Internet in the present scenario has become a gigantic source of information. There has been a tremendous rise in the variety of Internet applications with each application demanding a specific performance criteria to be satisfied. Routers presently use Passive Queue Management (PQM) mechanisms and hence, merely have any control over the queue occupancy. Therefore, there has been an increased interest...
Wireless internet has become popular in recent years due to the tremendous growth in the number of mobile computing devices and high demand for continuous network connectivity regardless of physical locations. In this paper, we investigate the effects of routing protocols on the performance of Transmission Control Protocol (TCP) variants in multi-hop wireless networks. Through simulations we study...
In today's business environment, web applications become more and more complex but they still need to be flexible for changes, easy to maintain and the development life cycle need to be short. A reflective technique seems to be the best way to achieve flexibility of the web applications when adding the personalization features like recommendations, special offers, etc. Most of the algorithms help...
