Smart Grid solutions are being driven by the desire for more efficient energy usage worldwide. Nowadays Smart Grid communications network is a heterogeneous network based on many different standards. This paper describes the suitability of Wi-Fi technology for use in the Smart Grid backhaul.

In this work, the impact of physical/logical network topol-ogy on parallel matrix computation is studied on an Intel Touchstone DELTA mesh and three generations of hyper-cube multiprocessors. These machines are representative of the continued development of distributed-memory message-passing multiprocessors in the current decade. As the processor architecture and the network hardware continue t...

Ad hoc network is an infra structure less network, which is formed by heterogeneous mobile devices like laptops, PDAs, cell phones etc. which have different computational capability, power, hardware and software. These devices can be integrated to form an infrastructure known as grid. In order to effectively share and use these heterogeous resources we visualize a grid overlay on this network. ...

With the development of grid computing, Data Grid, as an important branch of Grid Computing focuses on supporting an efficient management mechanism for controlled sharing and large amounts of distributed data. Data intensive jobs are one major kind of jobs in Data Grid, and their scheduling strategies are regarded as one of the most important research fields. Dynamic replication in data grid ai...

We will present a protocol of fault tolerant grid migration system using network storage. Our proposed grid migration system has capability to recover from fault in autonomic manner. We also implemented a grid migration system using Globus Toolkit4 and the network storage. Performance evaluation will be reported to show effectiveness of the fault recovery.

In data grid, large quantity of data files is produced and data replication is applied to reduce data access time. Efficiently utilizing grid resources becomes important research issue since available resources in grid are limited while large number of workloads and large size of data files are produced. Dynamic replication in data grid aims to reduce data access time and to utilize network and...

Although the net processing power in the network is increasing steadily, it is heterogeneous. Hence the immense compute-power may be underutilized at certain points while it remains inadequate at others. This paper proposes an active network-based framework that views the entire network as a single-entity to effectively utilize the network resources. The single-entity model is enabled by establ...

A wireless sensor network is made up of tiny size sensor nodes having the limited computation capability, bandwidth, power supply and storage. These networks are generally deployed in inaccessible tough terrains and hence network failures either due to physical damage or energy depletion are quite inevitable. Also, in the absence of manual intervention, these networks must operate autonomously ...

The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...
