Moreover, the synchronization of EAN is studied; the result shows that the stochastic networks are more poorly synchronized than their deterministic counterparts. These models can well mimic some real systems. Firstly, two dimensional random Apollonian networks and two dimensional EAN are maximal planar graphs, which may be helpful for designing printed circuits. Secondly, V-HDRAN can be mapped into the Yule process, which was inspired by observations of the statistics of biological taxa. From this perspective, V-HDRAN can find some applications in biological systems. Thirdly, all networks of this type consist of complete graphs; this particularity of the composing units can provide a comprehensive aspect to understand some real-life systems making up of complete graphs, such as movie actor collaboration networks, scientific collaboration networks and networks of company directors.
