Formalism Challenges of the Cougaar Model Driven Architecture
نویسندگان
چکیده
The Cognitive Agent Architecture (Cougaar) is one of the most sophisticated distributed agent architectures developed today. As part of its research and evolution, Cougaar is being studied for application to large, logistics-based applications for the Department of Defense (DoD). Anticipiting future complex applications of Cougaar, we are investigating the Model Driven Architecture (MDA) approach to understand how effective i t would be for increasing productivity in Cougarbased development efforts. Recognizing the sophistication of the Cougaar development environment and the limitations of transformation technologies for agents, we have systematically developed an approach that combines component assembly in the large and transformation in the small. This paper describes some of the key elements that went into the Cougaar Model Driven Architecture approach and the characteristics that drove the approach.

Model-Driven Architecture for Agent-Based Systems
The Model Driven Architecture (MDA) approach uses a platformindependent model to define system functionality, or requirements, using some specification language. The requirements are then translated to a platform-specific model for implementation. An agent architecture based on the human cognitive model of planning, the Cognitive Agent Architecture (Cougaar) is selected for the implementation p...

The maturation of multi-agent systems permits increasingly sensitive and security related problems to be addressed. In particular, the Cougaar architecture has demonstrated itself to possess significant scalability and survivability features. In this paper, a wireless door-entry security system built using Cougaar is discussed. The key contribution of this paper is to begin a discussion regardi...
متن کاملMulti-Tier Communication Abstractions for Distributed Mult-Agent Systems
Most Multi-Agent System (MAS) architectures use a single communication model for sharing of data, propagation of tasking, and negotiation for services. We describe the Cougaar distributed multi-tiered MAS infrastructure which uses different communication techniques at each tier to gain large-scale parallelization, scalability and asynchronous operation without sacrificing the ability to support...
متن کاملApplying Cougaar to Integrated Critical Infrastructure Modeling and Simulation
Protecting critical infrastructures, such as electrical power grids, has become a significant concern for many nation states in recent years. Increasing attention is being given to the problem of infrastructure modeling, in order to help identify and redress potential vulnerabilities. Understanding critical infrastructure behavior involves modeling not only individual infrastructures, but also ...
