Abstract: The indoor navigation network can guide the indoor evacuation in fire. Thus, we propose a network robustness analyzing solution for 3D indoor navigation, which integrates the topological network features and 3D geometric coordinates. The test result shows that the introduced solution could generate the topological feature and geometric coordinate feature for the given networks, and provides several optimized plans for the damaged navigation networks.
