Context-aware policy-based framework for self-management in delay-tolerant networks: A case study for deep space exploration

Policy-based management allows the deployment of networks offering quality services in environments beyond the reach of real-time human control. A policy-based protocol stack middleware, the context-aware broker, has been developed by the authors to autonomically manage the remote deep space network. In this article example policy rules demonstrate the concept, and prototype results from ns-2.30 show the overall positive cost-benefit impact in an example scenario.
