Research of wireless communication network frequency assignment based on modified genetic algorithm

In combination with the application of genetic algorithm in the field of frequency assignments,a heuristic fre-quency assignment method is proposed in this paper based on the analysis of frequency assignment link in wireless communica-tion. It can assign the channel allocation by modifying the selection mode,and adjusting the crossover and mutation probability adaptively. The simulation results show that this method is scientific and practicable,can prevent local optimization effectively, accelerate the population evolution,reduce the number of iterations,and converge to the optimal solution quickly.
