Our hands-on validation has revealed that VMware ESXi 3.5 can achieve a significantly higher VM density than Microsoft Hyper-V, allowing users to consolidate more servers on a VMware platform. While VMware’s advantage may not be surprising, given its 10-year history of leadership in this space, the magnitude of the difference is striking: VMware ESXi 3.5 demonstrated at least a 50% (1.5 to 1) d...

In current scenario cloud computing is most widely increasing platform for task execution. Lot of research is going on to cut down the cost and execution time. In this paper, we propose an efficient algorithm to have an effective and fast execution of task assigned by the user. We proposed an effective communication framework between broker and virtual machine for assigning the task and fetchin...

A. D’Atri and D. Saccà (eds.), Information Systems: People, Organizations, Institutions, and Technologies, DOI 10.1007/978-3-7908-2148-2_20, © Springer Physica-Verlag Berlin Heidelberg 20 0 Abstract A transaction is a bilateral exchange between two parties in which goods are delivered in return for payment. In virtual enterprise environments, transactions are the principal means of collaboratio...

Simulation and emulation are commonly used to study the behavior of communication networks, owing to the cost and complexity of exploring new ideas on actual networks. Emulations executing real code have high functional fidelity, but may not have high temporal fidelity because virtual machines usually use their host’s clock. To enhance temporal fidelity, we designed a virtual time system for vi...

An X.25 virtual circuit is opened on demand when a datagram arrives at the network interface for transmission. A virtual circuit is closed after some period of inactivity (the length of the period depends on the cost associated with an open virtual circuit). A virtual circuit may also be closed if the interface runs out of virtual circuits. An algorithm for managing virtual circuits during peak...

virtual water adds a new dimension to crop trades and provides a new way of thinking about water scarcity. a systematic analysis of virtual water flows requires integration of all critical drivers of virtual water flows under a single consistent framework. the aim of this study was to assess virtual water flows related to trades of grain crops (wheat, corn, rice, and coarse cereals) and their i...

In cloud computing, organizations can form the cooperation to share the available resource to reduce the cost. This is referred to as the multi-organization cloud computing environment. In this paper, we address the issues of virtual machine management and cooperation formation in such an environment. First, for the cooperative organizations, the optimization problem is formulated and solved fo...

The design and development of cost effective rehabilitation aids is a challenging task for biomedical research community. The biopotentials such as EEG, EMG, ECG and EOG that are generated from human body help in controlling the external electronic devices. In the recent years, the EOG based assistive devices have gained importance in assisting paralyzed patients, due to their ability to perfor...

Distributed Virtual Environment (DVE) systems model and simulate the activities of thousands of entities interacting in a virtual world over a wide area network. These systems are composed of many servers each of which is responsible to manage multiple clients who want to participate in the virtual world. Each server delivers the information updated from different clients to other client in vir...
