A Dynamical-Network Model with Hierarchical Controls for Cognitive Military Satellite Communications

摘要

A modeling framework is developed that enables analysis and design of cognitive radio technologies for military satellite communication networks. The main components of the model are: 1) a multi-tiered queueing network that captures data transmission within the network; 2) access and routing models for primary and cognitive users, abstracted as mixed supervisory and bottom-up controls. A complete set of governing equations for the model are presented, as a starting point for simulation and formal evaluation. Finally, a specific use case is developed, on comparing static and dynamic bandwidth allocation (supervisory control) schemes in the military satellite backbone.
