Utility-based distributed heterogeneous network management

Typical military networks consist of many types of devices and network links. The objective of this proposal is to develop a theoretical approach for network management in heterogeneous wireless network environments. The technical approach focuses on using distributed utility optimization adapted for wireless networks. Particular challenges imposed by wireless networks are: user mobility and dynamic topology, channel interference and varying link capacities over time. Three classes of traffic have been selected to be studied under these network conditions: video, voice and tracking. Leveraging our prior work in military concept of operations research, this work will introduce role-based utility functions based on mission requirements. We will combine (previously separate) adaptations of system decomposition techniques to wireless networks and non-concave (and role-based) utility functions and develop a unified network management structure. Using a proprietary modeling, simulation and optimization tool, the proposed approach will be evaluated for feasibility and to determine metrics of performance. Key to the evaluation task is the use of real-world scenarios and mission requirements for approach validation under practical conditions. There is a clear path to the usefulness and commercialization of any resulting technology through Drakontas' expertise in law enforcement communication networks arena. BENEFIT: 1. Unified network management structure for heterogeneous wireless networks 2. Mission requirements-based approach to utility optimization 3. Modeling, simulation and optimization of networks using real-world scenario characteristics
