Optimizing Resource Discovery Technique in the P2P Grid Systems

الملخص EN

Distributed discovery service is a main concept in the scalable and dynamic grid environments.

In this paper, based on the super-peer technique, we propose a new topology for the grid discovery service.

The model is designed in such a way that each super-peer within the cluster has the routing indices (RIs) based on cobweb and uses the hop-count routing index (HRI) to select the best neighbor.

Besides, each super-peer includes a cache table, which stores the query and the query results.

Furthermore, from the point of view of the response time and the number of submitted messages, we compare the new model with an existing method.

An illustrative simulation is also presented to show the efficiency and validation of the new technique.
