To enhance the invulnerability of WFAN,WFAN was analyzed from the perspective of network topology. On this basis,super wires and super nodes were introduced to improve WFAN invulnerability. Moreover,a novel centrality metric was proposed and on this basis,two layout schemes( i. e.,the layout scheme of super wires and layout scheme of super nodes) were established. Simulation results indicate that through constructing super wires and super nodes around key nodes,the established layout schemes are able to make the centrality distribution of WFAN more uniform,which in turn helps the network avoid significant performance degradation caused by failures of a few key nodes and thus enhance the invulnerability of WFAN with less construction costs.
