Improving the Tracing System in PANGEA Using the TRAMMAS Model

Abstract

This paper presents the integration of the tracing model TRAMMAS in an agent platform called PANGEA. This platform allows to developed multiagent systems modeled as Virtual Organizations. The concepts of roles, organizations and norms are fully supported by the platform assuring flexibility and scalability. Before TRAMMAS, this platform uses a Sniffer Agent to trace the information reducing its scalability as a centralized mechanism. TRAMMAS proposes the use of event tracing in multiagent systems, as an indirect interaction and coordination mechanism to improve the amount and quality of the information that agents can perceive in order to fulfill their goals more efficiently. Moreover, the event tracing system can help reducing the amount of unnecessary information.
