There is an increasing demand to introduce adaptive capabilities in Distributed Real-time and Embedded (DRE) systems that execute in open environments where system operational conditions, input workload, and resource availability cannot be characterized accurately a priori. To meet these needs, this paper presents the Hierarchical Distributed Resource-management Architecture (HiDRA), which provides adaptive resource management using control-theoretic techniques that adapt to workload fluctuations and resource availability.
