— The service-oriented architecture has come a long way in solving the problem of reusability of existing software resources. Grid applications today are composed of a large numb...
The Tree-of-Hubs Location Problem is studied. This problem, which combines several aspects of some location, network design and routing problems, is inspired by those transportati...
In this paper, we introduce the combinatorial auction model for resource management in grids. We propose a combinatorial auction-based resource allocation protocol in which a user...
We define a probe to be a single action sequence computed greedily from a given state that either terminates in the goal or fails. We show that by designing these probes carefull...
In this paper, we present the design and implementation of Ovid, a browser for Grid-related information. The key goal of Ovid is to support the seamless navigation of users in the...
