Spatial Information Network Modeling and Analysis Based on Cognitive Technology

Aiming at ubiquitous and heterogeneous network model, spatial information network was constructed for the complex space environment, real-time adjustment to configure the network system, dynamicly and intelligently adapting to the environment and guiding future independent decision. There are corresponding theoretical guidance and support mechanisms on the network dynamic sensing and self-healing capabilities. Starting from the mechanism of cognitive technology, the concept of cognitive spatial information network was defined, the role of feedback loops in the cognitive process was elaborated, and the characteristics of the cognitive spatial information network was analyzed. A hierarchical cognitive network design model was proposed. For the initiative aware features of the network, the model uses the energy spectrum sensing method in cognitive radio and qualitatively analyzes the perceived performance of the cognitive spatial information networks. The simulation results show the range of the algorithm applied in space information network.
