Providing A Method Based On The Combination Of The Tree an‎d Super-Peer Structures For Resource Discovery In The Grid Environment

The grid is a new generation of distributed networks that supply resources required for applications with high processing and memory loads. Given the specific features of the grid environment, including high dynamics and heterogeneity of resources/elements, some challenges are encountered on this computational platform. One of the main services of the grid platform is the discovery of resources. The purpose of the resource discovery service is to identify a list of resources available for assigning tasks. In this paper, using the assignment of prime numbers as the weight of the index tree nodes, and by combining the hierarchical method with a peer-to-peer (P2P) method, a new algorithm has been presented, in which several networks with the hierarchical internal structure are combined by means of the super-peer method. The results of the experiments and their comparison with previous methods indicate the improvement achieved by the proposed method in terms of the number of nodes visited in the searching process and by reducing the processing load induced by the calculation of the weight of the tree edges.
