Maintaining QoS for Publish/Subscribe Middleware Via Autonomic Adaptation

Quality of Service (QoS)-enabled Publish/Subscribe (Pub/Sub) middleware provides powerful support for data dissemination. It is hard, however, to maintain specified QoS properties such as reliability and latency in dynamic environments such as disaster relief operations or power grids. For example, managing QoS manually is not feasible in dynamic systems due to slow human response times and the complexity of managing multiple interrelated QoS settings. Autonomic adaptation provides a promising approach to maintaining QoS properties of QoS-enabled pub/sub middleware in dynamic environments.
