October 2012 - Technical Report Resource Allocation in Dynamic Environments

Topics: Ultra-Large-Scale Systems

Authors: Jeffrey Hansen, Scott Hissam, B. Craig Meyers, Gabriel Moreno, Daniel Plakosh, Joe Seibel, Lutz Wrage

When warfighting missions are conducted in a dynamic environment, the allocation of resources needed for mission operation can change from moment to moment. This report addresses two challenges of resource allocation in dynamic environments: overstatement of resource needs and unpredictable network availability.

December 2010 - Technical Report Adaptive Flow Control for Enabling Quality of Service in Tactical Ad Hoc Wireless Networks

Topics: Software Architecture

Authors: Jeffrey Hansen, Scott Hissam, B. Craig Meyers, Edwin J. Morris, Daniel Plakosh, Soumya Simanta, Lutz Wrage

The network infrastructure for users such as emergency responders or warfighters is wireless, ad hoc, mobile, and lacking in sufficient bandwidth. This report documents the results from 18 experiments to investigate Adaptive Quality of Service, an approach to enable applications to fulfill their missions despite tactical network infrastructure limitations.
