Abstract Component-based middleware frameworks that support distributed agent societies have proven to be very useful in a variety of domains. Such frameworks must include support for both agents to implement business logic and runtime adaptation to overcome the inherent limitations of unreliable, resource-constrained environments. Regardless of how any particular middleware framework is organized into components, the business logic and adaptation support will inevitably require some crosscutting of the dominant decomposition. In this paper, we discuss a spectrum of dynamic crosscutting techniques in support of runtime adaptation that we have implemented in Cougaar, a component-based service-oriented architecture. We describe these crosscutting techniques and show how they can be used to enhance the flexibility and survivability of agent-based applications.
