Investigation of DHT Based P2P Resource Discovery Algorithms in Grid Environment

Abstract

Grid Resource Discovery can be defined as searching and locating resources across multiple administrative domains. It returns a list of locations which satisfied the requirements and forms a resource service chain to complete the task. An efficient resource discovery mechanism is one of the fundamental requirements for grid computing systems, as it aids in resource management and scheduling of applications. Resource discovery activity involves searching for the appropriate resource types that match the user's application requirements. Various kinds of solutions to grid resource discovery have been suggested, including centralized and hierarchical information server approaches. This paper, focuses on DHT based Structured Peer-toPeer Chord protocol and its variations in recent years. The four recently developed algorithms for quick Grid Resource Discovery using P2P Chord Protocol are concentrated in this paper. The results of the new implementations are tested in NSC-SE simulator and performance analysis is given at the end of this paper.
