Grid computing technologies are increasingly being used to aggregate computing resources that are geographically distributed across different locations. Commercial networks are being used to connect these resources, and thus serve as a fundamental component of grid computing. Since these grid resources are connected over a shared infrastructure, it is essential that we consider their effect dur...

The Smart Grid concept introduces an updated architecture and new elements to the traditional power grid. As a result, existing survivability schemes that have been designed with a centralized architecture in mind are either inefficient or no longer applicable. In this paper, we review several solutions that have been suggested in the literature in order to ensure the proper operation of the po...

Grid-connected battery energy storage systems with fast acting control are a key technology for improving power network stability and increasing the penetration of renewable generation. This paper describes two battery energy storage research facilities connected to the UK electricity grid. Their performance is detailed, along with hardware results, and a number of grid support services are dem...

Fakultät für Mathematik, Informatik und Physik Institute für Informatik Doctor of Philosophy by Muhammad Murtaza Yousaf Grid Computing promises a supercomputing-like performance at low cost, which means that a large number of users should have the opportunity to solve their problems on a widely accessible platform. In order to meet the claimed performance, the Grid research community needs to d...

Wireless sensor networks (WSNs) have been greatly developed and emerged their significance in a wide range of important applications such as acquisition and process information from the physical world. The evolvement of Grid computing has been based on coordination of distributed and shared resources. A Sensor Grid network can integrate these two leading technologies enabling real-time sensor d...

This paper precisely analyzes the wire density and required area in standard layout styles for the hypercube. It shows that the most natural, regular layout of a hypercube of N nodes in the plane, in a N N grid arrangement, uses b2N=3c+ 1 horizontal wiring tracks for each row of nodes. (In the process, we see that the number of tracks per row can be reduced by 1 with a less regular design, as c...

Wireless grid can provide consumers ubiquitous broadband wireless services with convenience, robustness and mobility, which is one of the most promising alternatives of fixed wireless access networks. As the deployment of Wide City has accelerated quickly, this study focuses on the key technologies of wireless grid in ubiquitous broadband wireless services, such as antennas, MAC design, channel...

In terms of the transmission network development case selection, there are deferent emphases for the development department, power dispatching and other departments, and evaluation indexes and methods in case selection of transmission network development are deferent to take, as a result it is difficult for the developing, scheduling and other departments of grid to form an objective, comprehen...

The Internet communication infrastructure (the TCP/IP protocol stack) is designed for broad use; as such, it does not take the specific properties and requirements of Grid applications into account. This one-size-fits-all approach is far from being optimal – general network mechanisms, while useful for the Grid, cannot be as efficient as customized solutions. In this paper, we list properties t...
