It is of great importance to control the electromagnetic spectrum and optimize the use of spectrum resource because electromagnetic interferences between different devices may cause vicious influence while combating in formation. Traditional random algorithms for the optimization of spectrum use suffer from painfully slow optimization speed. In this paper, a model of Electro Magnetic Compatibility(EMC) network in the case of formation is developed based on the complex network theory. By maximizing the network performance in terms of both benefit and cost, this paper proposes a rule optimization algorithm of EMC network considering node importance. Both theory analysis and simulation results show that optimization speed is increased by 13.35% and the optimization performance is enhanced. The proposed algorithm not only accelerates the optimization for the use of spectrum resource but also provides a theoretical reference for practical applications.
