Many military environments require the dissemination of data streams from a set of sensors (such as video sensors, acoustic arrays and short-range radars) to a set of missions over a multi-hop wireless network. Network Utility Maximization (NUM) techniques have been extensively investigated, for their ability to achieve close-to optimal bandwidth sharing using purely-distributed control algorithms. In this talk, we will describe some enhancements and modifications to the base NUM framework for supporting some unique requirements for mission-oriented military applications. The first part of the talk describes techniques to adapt NUM-based strategies to scenarios where each mission requires data from multiple sensor streams, and where each sensor’s feed is distributed to different receivers along different routes. The second part of the talk addresses the issues of priorities for quasi-elastic missions, with higher-priority missions being characterized by a minimal utility requirement.

The Colloquium is supported by generous contributions from the Bloomberg, Information Builders, Inc., and Netlogic, Inc.
