Researches on the topology optimization and simulation against attacks for MCN based on redundant links

Based on the classical scale-free network model (BA model), this article designs an adjacent network of which key nodes are constructed to be like the structure of rotary interchange, and puts forward a method of the topology optimization for military communication networks by redundant links, and through researches on the arithmetic of the topology optimization. BA model and the method proposed are simulated by MATLAB etc. The results of the simulation show that the method can improve the ability of the scale-free network well to resist against attacks, which has less influence on the network.
