Abstract：To remain the consistency of network simulation model and real network, an algorithm to create stochastic simulation network was proposed. Firstly, the new probability connectivity formula was deduced. Then, the convergence degree of the models were discussed. Finally, the new model of the stochastic network simulation were tested and analyzed. The simulation and analysis of the model performances indicate that this model is universal and can be customized. Compared with existing algorithms, the proposed algorithm is well convergent and has linear approach to simulate real network.
