Vulnerability analysis of air traffic network based on complex network theory

Aiming at the problem of poor communication coverage ability of air traffic network nodes, a vulnerability analysis method for air traffic network based on complex network theories was proposed. A complex multi-layer network model was established using both distribution structure model and transmission channel model for network nodes, and the density of network nodes was optimized and adjusted with the self-adaptive time-varying delay-constraint-error correction method. The fusion degree of distribution density of air traffic network nodes was tracked and controlled, and the information state vector was predicted by taking the node area coverage as constraint condition. The coverage capacity of air traffic network was calculated according to the density function of control nodes, and the optimal deployment of air traffic network nodes was completed with the energy balance control method to realize the vulnerability analysis of air traffic network. The results of simulation test show that the as-proposed method can improve the coverage of air traffic network nodes and enhance the communication coverage ability of network in comparison with traditional methods.
