In mission critical applications of distributed information systems, autonomous information resources are coordinated to meet the information demands of client specific decision-support views. The current approach to view coordination relies on design-time trade-offs to select a static view coordination policy from a set of available policies. This approach is not robust and does not respond well in a dynamic environment with shared infrastructure, and dynamically changing missions, priorities, preferences, and constraints. This paper introduces, NAVCo, a negotiation-based adaptive view coordination approach that allows view coordination policies to be dynamically negotiated and adapted at run-time in response to dynamically changing conditions.
