Modeling and analysis for multilayered complex communication network of satellite navigation system

This study is extended to construct the network model, the node model, and the link model of complex communication network for satellite navigation system (CCN-SNS) based on the hierarchical architecture. Firstly, a method called snapshots was proposed to describe the dynamic topology for CCN-SNS; secondly, another method was put forward to model the different nodes of the CCN-SNS; thirdly, the different links between every two different nodes were modeled. Therefore, based on the OPNET tools, a simulation for the CCN-SNS, which contains the models that proposed earlier used to analyze the navigation accuracy and network transmission performance, was performed.
