Military heterogeneous networks often suffer from node or edge failures due to attacks, which lead to whole network topology segmentation or even paralysis. Therefore, structural invulnerability is the major technical bottleneck that impedes the combat capability of military heterogeneous system. Nodes are mainly considered in current methods, with little attention paid to edges. As such, current methods cannot accurately evaluate the structural invulnerability of military heterogeneous networks. This paper presents a new method of evaluating the survivability of military heterogeneous networks, based on network structure entropy. A model of survivability is proposed based on the network irreversibility which considers not only the nodes but also the edges. The node criticality is calculated by the level flow betweenness. Edge criticality is put forward based on the edge correlation factor and information transmission efficiency. Simulation results show that this invulnerability measure has the characteristics of high sensitivity and high precision, which will provide a theoretical basis for designing and optimizing the structure of the military heterogeneous network.
