Abstract:
Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. The required resources must be accessible for Grid applications on demand, which makes the resource discovery a critical service in Grid environments. In recent years, diverse techniques are provided to index and discover the Grid resources. The response time and message load during the search process highly affect the efficiency of resource discovery. This paper proposes a new technique to forward the queries based on the resource types which are accessible through each branch in hierarchical Grid resource discovery approaches. The proposed technique is simulated in GridSim and the experimental results indicated that it is able to reduce the response time and message load during the search process especially when the Grid environment contains a large number of nodes.
