Recently, Cognitive radio and Smart Grid are two areas which have received considerable research impetus. Cognitive radios are fully programmable wireless devices that can sense their environment, and dynamically adapt their transmission waveform, channel access method, spectrum use, and networking protocols. It is widely anticipated that cognitive radio technology will become a general-purpose...

Demanding applications like distributed multi-physics simulations benefit from the combined computational performance and data storage of multiple clusters. A reservation mechanism spanning these clusters ensures the availability of all selected resources. Complex workflows with chronological dependencies are supported. This approach addresses network resources the same way as computation and s...

This paper studies the collective communication in the grid computing environment, which is characterized by the combination of heterogeneous networks as well as uneven, long communication delay. Efficient collective communication requires communication schedule, which in turn requires network information. When the network information is not accurate or network faults occur, the performance of ...

We consider the problem of embedding the n-dimensional cube into a rectangular grid with 2n vertices in such a way as to minimize the congestion, the maximum number of edges along any point of the grid. After presenting a short solution for the cutwidth problem of the n-cube (in which the n-cube is embedded into a path), we show how to extend the results to give an exact solution for the conges...

In the following an approach for the quantitative inclusion of the soft-factor cooperation climate in the enterprise oriented performance analysis is presented. This quantitative analysis is realised by an adapted value benefit analysis in combination with the Repertory Grid methodology. Through this a comprehensive model representing value-adding process related and valueadding-process neutral...

In a basic grid computing system, every computer can access the resources of every other computer belonging to the network. In the ideal grid computing system, every resource is shared, turning a computer network into a powerful supercomputer. It’s a special kind of distributed computing. In distributed computing, different computers within the same network share one or more resources. Cloud co...

The computational Grid concept is gaining great popularity as the best way to deliver access to a wide range of distributed computing and data resources. But, as Grids move from an experimental phase to real production and their deployment in the Internet significantly increases, controlling the security of a Grid application becomes imperative. The most significant Grid security issue is that ...

Highly shared resources over multiple grid platforms make insecurity and privacy abuse major obstacles hindering general-purpose Grid applications. A scalable grid system demands the allocation and release of resources dynamically. A distributed Grid security (GridSec) architecture is introduced to meet these demands. The architecture is built with distributed firewalls, packet filters, securit...

Grid computing is an emerging technology that enables global resource sharing. In Korea, the K*Grid provides an extremely powerful research environment to both industries and academia. As part of the K*Grid project, we have constructed, together with the Korea Institute of Science and Technology Information and a number of domestic universities, a supercomputer Grid test bed which connects seve...
