DRN: A CORBA-Based Distributed Resource Navigation System for Data Grid
نویسندگان
چکیده
Data grids are becoming increasingly important for sharing distributed data and information in collaborative environments. This paper presents a CORBA-based Distributed Resource Navigation system consisting of Resource Agents and Navigation Service. The former one is a middleware that provides applications with a uniform set of operations to access heterogeneous distributed storage resources including file systems and database systems, and archival storage systems. The latter one is a metadata navigation service which is utilized by DRN to improve data publishing and lookup efficiency. Experiments show that CORBA-based DRN can provide the essential data virtualization services, and that Navigation service and Resource agent have a good performance with concurrent accesses.

Model Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation
This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...
متن کاملA New Job Scheduling in Data Grid Environment Based on Data and Computational Resource Availability
Data Grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. The heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. Most existing scheduling algorithms in Grids only focus on one kind of Grid jobs which can be data...
متن کاملBuilding Light Weight CORBA Based Middleware for the CAN Bus Systems
The software components of embedded control systems get extremely complex as they are designed into distributed systems consisting of a large number of inexpensive microcontrollers interconnected by low-bandwidth real-time networks such as the controller area network (CAN). While recently emerging middleware technologies such as CORBA and DCOM address the complexity of distributed programming, ...

Recently emerging component-based middleware technologies such as CORBA are widely believed to be a viable solution to the software complexity problem of a distributed embedded computer control system. However, general purpose middleware systems are not immediately applicable to a distributed embedded system since they should run in a platform with severe resource limitations. In this paper, we...

The software components of embedded control systems get extremely complex as they are designed into distributed systems consisting of a large number of inexpensive microcontrollers interconnected by low-bandwidth real-time networks such as the controller area network (CAN). While recently emerging middleware technologies such as CORBA and DCOM can partially deal with such complexity, they canno...
