Trust issue is presently a research hotspot in military information grid. This paper first proposes a SOA-based unified identity authentication scheme, which can transplant the existing account systems into the new one by means of account association, to solve the problem of inter-network identity authentication. Then, this paper develops an asymmetric trust model based on fuzzy logic. This model...
According to the classification principles of educational information in LOM, and the characteristics of grid community and resource distribution in grid, on the basis of a proposed model of grid community based education resource, the brief paper puts forward constructing the concept of Equivalent grid community group, building the mechanism of resources-sharing and information-spreading between...
Buffer analysis is one of the most important GIS functions to take spatial analysis. Based on our experience on EO data parallel processing, we take buffer generation as an example to research how to accelerate the speed and scale of GIS operations. This paper analyzes the procedure of the original sequential algorithm, and then gives out the mechanism of the parallelization. As a result, it will...
The build of educational resources is the basis of e-education. Grid technology realizes the extensive sharing of educational resources. This paper, based on analyzing metadata standards of educational resources, takes LOM as the description of educational resources in grid. In addition, this paper uses grid resource description frame (RDF) to describe LOM formally, and builds a RDF model of LOM focused...
This paper analyzes grid resources organization, elaborates on the fundamental principles of the ant colony algorithm, and proposes a grid resource discovery method based on the ant colony algorithm. We consider users request ontology as ants, take search resource as food, and food source is the node of search target. The process of ants to find food is similar to the process of discovery grid resources.
