The coordination and scheduling of affiliated tasks to be run at different sites is a challenging problem, specifically in the domain of network performance monitoring. This paper presents a software implementation of the probes coordination protocol (PCP) which provides a solution to this problem. The PCP allows tasks to be executed regularly on a multitude of sites without the need for repeated...
Grid portals are web gateways aiming at providing a pervasive and ubiquitous access in grid to computational resources, tools, instruments, datasets and metadata via standard Web protocols. Moreover, they provide enhanced problem solving capabilities to deal with modern, large scale scientific and engineering problems. Data grid management systems are becoming increasingly important in the context...
In modern manufacturing grid, different security mechanisms of systems bring usage complexities and security risks. Single sign-on (SSO) can enhance the enterprise applications security and improve the overall efficiency. A security infrastructure is proposed by the token based authentication protocol in intranet. It is designed and developed on the technology of Java GSS-API, JAAS, Kerberos and SPNEGO...
In modern Collaborative Manufacturing, different security mechanisms of systems bring usage complexities and security risks. Grid Security Infrastructure (GSI) enables secure authentication and communication over computer networks. It is designed and developed on the technology of Java GSS-API, JAAS, Kerberos. The key technologies such as integrating with application server are specially discussed...
With the availability of high performance networks and the increase in the number of online scientific instruments, remote instrumentation is a topic with much popularity lately, promising better instrument utilization, easier collaboration between distant organizations and diminution of travel-related costs and overhead. At NRC we needed a simple and secure method for researchers to remotely access...
With the progress of researches on the integration of Geographic Information System (GIS) and Remote Sensing (RS), digital earth, and information sharing, to publish RS images on Internet has become a significant research work. This paper presents an efficient algorithm to build image pyramid model for convenient data storage and retrieval and proposes two distributed cutting algorithms under the...
