A policy-driven multi-agent system for OGSA-compliant grid control

The emergence and the development of OGSA compliant grid provide powerful means for the integration and interaction of applications (grid services) within a virtual organization (VO). However, it is still a challenge to control the composition, transaction, and coordination, of grid services, according to the dynamic business requirements of a VO. Based on the policy-based management and autonomous intelligent agents, this paper proposes a framework for OGSA-compliant grid control. In this system, individual agent (task agent) is in charge of composing grid services and taking part in the social interactions within a VO. Several task agents and a management agent (MA) form a VO. The business requirements or user´s preferences are represented as policies, which are used to control the behaviors of agents.
