A Centralized Service Discovery Approach for Agent-based Cloud ComputingSystem

摘要

Agent-Based Cloud computing is emerging as a paradigm in many domains, including service discovery, servicecomposition and service negotiation, etc. It achieves autonomous resource allocation and resource management bydelegating requests to agents. Agents utilized the obsolete acquaintance network and Service Capability Tables (SCTs) torecord and schedule agents for service discovery. These approaches are unable to perform global search under the intermittentand volatile cloud computing environment. In this paper, we propose a robust service discovery approach with localand global service discovery capabilities. We validate the proposed approach in different granularity of agent networkscale. Experimental results demonstrate that our approach outperforms the SCTs based approaches in the aspect of dataavailability consistently.
