Application QOS Based Time-Critical Machine-to-Machine Resource Management in BM/C2 Systems
E. Douglas Jensen · 2004
This paper summarizes a novel paradigm for expressing, enforcing, and formally reasoning about time-criticality of machine-to-machine resource management in battle management (BM) and C2 systems. Such systems are largely dynamic and asynchronous, and have time frames of O(10-1) seconds and higher. Thus they fall into a neglected gap between traditional static periodic “real-time ” systems, and tradi-tional “any time ” scheduling/planning systems (e.g., for logistics). The paradigm uses applica-tion-level QoS metrics (such as track quality, circular error probable, etc.) to derive utility functions for completing tasks, and then uses those utility functions for resource management. This paradigm has been successfully employed in several experimental BM/C2 demonstration systems, and is the topic of on-going research by industry and academia.
