Formalizing Service Publication and Discovery in Grid Computing Systems

Considering the autonomy of resources in the grid environment and based on the service-oriented thought, a resource management system for grid computing can be abstracted to a multi-agent system that consists of service requestor agents, service provider agents and service broker agents. For looking into the interaction characteristics of agents, the formal method is adopted. Firstly, we present an abstract model of agent-based service publication and discovery for resource management in grid computing systems, and specify agent actions with π-calculus in the grid context. Secondly, we define the interaction protocol among agents as processes. Finally, The consistency between agent actions and the interaction protocol is discussed.
