SEMANTIC TECHNOLOGY AND SUPER-PEER ARCHITECTURE FOR INTERNET BASED DISTRIBUTED SYSTEM RESOURCE DISCOVERY

Resource/service discovery is a very vital issue in Internet based distributed systems such as Grid and Cloud computing. In this paper we address the RD issue in intergrid. We design a service discovery framework by integrating semantic technology, peer-to-peer network and intelligent agents. The framework has two main components which are service description, and service registration and discovery models. The earlier consists of a set of ontologies that are used as a data model for service description and services to accomplish the description process. The service registration is based super-peer architecture to organize the nodes and on ontology to manage the node organization. In addition to that, we introduce intelligent agents to automate the discovery process. We evaluate the framework via simulation experiments, and the result confirms the effectiveness of the framework in satisfying the required RD features (interoperability, scalability, decentralization and dynamism).
